Lingual thyroid carcinoma with nodal metastasis

OBJECTIVES: To discuss treatment options and surgical management of lingual thyroid carcinoma with cervical metastasis. STUDY DESIGN: Lingual thyroid is relatively uncommon, and carcinoma of the lingual thyroid is extremely rare, with only 40 cases reported. We report a new case of a young female who presented with a cervical neck mass found to represent metastatic papillary thyroid carcinoma. Further workup revealed the patient's only thyroid tissue was located at the tongue base and was the site of the primary tumor. Management of lingual thyroid carcinoma and review of the literature is discussed. METHODS: A case report and review of the literature of lingual thyroid carcinoma. RESULTS: A young female presented with a left neck mass diagnosed as metastatic papillary thyroid carcinoma. Review of the computed tomography scan of the neck revealed a tongue base mass, absence of an othotopic thyroid gland and bilateral cervical lymphandenopathy. Bilateral selective neck dissections with removal of the tongue base lesion confirmed the diagnosis of lingual thyroid carcinoma with multiple left cervical nodal metastases. CONCLUSIONS: A case of lingual papillary thyroid carcinoma with cervical metastasis is reported. Treatment is best managed with surgical excision of all thyroid tissue followed by radioactive iodine ablation. Surgical approaches to the tongue base need to be considered based on the size of the lingual primary tumor and the need to address lymph node metastases gland. This is the first reported case in the literature of lingual papillary thyroid carcinoma presenting with cervical nodal metastasis in a female with absence of an orthotopic thyroid gland. This is also the first report to show that papillary and not follicular cell carcinoma is the predominating histopathology in lingual thyroid carcinoma.     

Positron emission tomography in the evaluation of synchronous lung lesions in patients with untreated head and neck cancer

BACKGROUND: Positron emission tomography (PET) with the glucose analogue fludeoxyglucose F 18 uses the increased glucose uptake that is observed in neoplastic cells. It can differentiate between benign and malignant pulmonary lesions in patients with lung tumors. Applications of PET in extracranial head and neck neoplasms have included evaluating patients with unknown primary lesions, detecting primary and recurrent head and neck tumors, monitoring response to radiotherapy, and evaluating the N0 neck in oral cavity carcinomas. Its role in determining the presence of synchronous lung lesions has not been defined. PATIENTS AND METHODS: A retrospective review of 115 patients who underwent PET between October 1994 and October 1996 was performed to evaluate extracranial head and neck neoplasms. Fifty-nine (51%) previously untreated patients with squamous cell carcinoma of the upper aerodigestive tract were analyzed. RESULTS: Fifteen patients (25%) had PET scans that were positive for synchronous lung lesions. Five patients had a disease process that did not warrant further investigation; they did not have pathological confirmation of their lung lesions. Of these, 3 died of disease within 2 months of the diagnosis of primary head and neck squamous cell carcinoma, 1 was unavailable for follow-up, and 1 had lung lesions that were considered metastatic and no pathological confirmation of lung lesions was obtained. The remaining 10 patients with positive PET scan findings were investigated further: 8 patients had biopsy-confirmed lung lesions; 5 patients had positive findings on chest x-ray films; 8 had positive findings on computed tomographic scans; and 3 had positive findings on bronchoscopy. The results of 2 PET scans were false-positive. The PET scans were important in altering treatment in 3 patients; of these, 3 had negative findings on chest x-ray films, 2 had positive findings on computed tomographic scans, and 1 had positive findings on bronchoscopy. CONCLUSIONS: The overall sensitivity, positive predictive value, and accuracy of PET were 100%, 80%, and 80%, respectively. The overall accuracy of radiography of the chest, computed tomography of the chest, and bronchoscopy was 70%, 90%, and 50%, respectively. The accuracy of PET over bronchoscopy was statistically significant (P<.05). PET appears to be a promising imaging modality for the detection of synchronous lung lesions in patients with negative findings on chest x-ray films.     

Incidence of occult thyroid carcinoma metastases in lateral cervical cysts

PURPOSE: To establish the incidence of thyroid carcinoma metastasis in adult patients presenting with apparently benign cervical cysts. The authors report their experience with four cases of papillary thyroid carcinoma who present with a lateral cervical cystic mass and no palpable disease in the thyroid gland. MATERIALS AND METHODS: A retrospective review of patients undergoing surgery for solitary cervical cysts in our clinic from 1994 to 2002 was performed. Patients with a clinically obvious primary malignancy, age less than 16 years were excluded from the study. RESULTS: Thirty-seven patients were identified. A diagnosis of benign cervical cyst was shown by histological examination of the resected specimen in 32 patients (86.4%), with a mean age of 34 years (range, 16-59 years). A diagnosis of squamous cell carcinoma metastasis arising from an occult tonsillary primary was confirmed histologically in one patient (2.7%). Papillary thyroid carcinoma metastasis was confirmed by histological examination of the resected specimen in 4 patients (10.8 %), with a mean age of 29 years (range, 18-37 years). Diagnostic studies performed included ultrasound, computed tomography scan, fine-needle aspiration (FNA), and excisional biopsy. FNA was found to be helpful in only one of the 3 cases with papillary thyroid carcinoma metastasis. Final histopathological examination exhibited primary focus in the thyroid gland in all 4 patients, with a mean size of 0.5 cm (range, 0.3-0.8 cm). CONCLUSION: Our data indicate that nearly 1 out of every 10 lateral cervical cysts in young adult patients represents lymphatic metastases from occult thyroid carcinoma. An excisional biopsy for definitive diagnosis should be undertaken without prolonged delay, even if FNA does not reveal malignancy.     

Diagnostic sensitivity of 18fluorodeoxyglucose positron emission tomography for detecting synchronous multiple primary cancers in head and neck cancer patients

We assessed the sensitivity of positron emission tomography (PET) for detecting synchronous multiple primary cancers, particularly synchronous esophageal cancers in head and neck cancer patients. We retrospectively reviewed 230 head and neck cancer patients. All the patients routinely underwent the following examinations: urinalysis, occult blood, tumor marker detection [squamous cell carcinoma (SCC), cytokeratin fragment (CYFRA), and carcinoembryonic antigen (CEA)], esophagogastroduodenoscopy, colonoscopy (when CEA was high or occult blood was positive), abdominal ultrasonography, plain chest computed tomography (CT), and PET. Bronchoscopy was performed when CT revealed lung shadow of central region. Synchronous multiple primary cancers were detected in 42 (18.2%) patients. The diagnostic sensitivity of PET for synchronous primary cancers was as follows: esophagus, 7.6% (1/13); stomach, 25.0% (2/8); lung, 66.7% (4/6); head and neck, 75.0% (3/4); colon, 0% (0/1); kidney, 0% (0/1); and subcutaneous, 100% (1/1). The sensitivity of PET for detecting synchronous esophageal cancers is low because these are early-stage cancers (almost stage 0–I). Therefore, it is necessary to perform esophagogastroduodenoscopy for detecting synchronous esophageal cancers. PET is an important additional tool for detecting synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous head and neck cancer and lung cancer is high. But PET has the limitation of sensitivity for synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous esophageal cancer is very low.     

Positron emission tomography in the management of unknown primary head and neck carcinoma

OBJECTIVE: To assess the role of positron emission tomography (PET) in the management of unknown primary carcinoma of the head and neck region. DESIGN AND SETTING: Prospective case series at an academic medical center. PATIENTS: Twenty-six patients with an open excisional biopsy or a fine-needle aspiration biopsy finding that confirmed squamous cell carcinoma of the cervical lymph nodes and no visible primary tumor (as determined by results of a comprehensive physical examination and computed tomography and/or magnetic resonance imaging) underwent PET. The standard evaluation consisted of a comprehensive head and neck examination that included fiberoptic laryngoscopy/nasopharyngoscopy, computed tomography and/or magnetic resonance imaging, and PET followed by panendoscopy with selected biopsies and tonsillectomy. MAIN OUTCOME MEASURES: Sensitivity, specificity, and positive and negative predictive values of PET to detect an occult primary tumor. RESULTS: The PET detected 8 occult primary tumors in 26 patients (detection rate, 30.8%). Four occult primary tumors (2 at the base of the tongue and 2 in the tonsil) were detected during routine panendoscopy with negative PET findings. The sensitivity of PET was 66.0%, with a specificity of 92.9%. The positive predictive value was 88.8%, and the negative predictive value was 76.5%. CONCLUSIONS: Positron emission tomography can be a valuable tool to identify a subset of patients with an occult primary tumor in the head and neck region. In addition, it can be used to screen for primary tumors below the clavicle. Early identification of the primary tumor may allow for more accurate tumor staging and targeted radiotherapy to minimize adverse effects and complications. A normal PET finding, however, does not eliminate the need for a careful panendoscopy with directed biopsies and tonsillectomy.     

Follicular adenoma in a juxtathyroidal thyroglossal duct cyst with papillary carcinoma in the adjacent thyroid gland

This patient presented with a neck mass diagnosed as a papillary thyroid carcinoma by fine-needle aspiration. Preoperative computed tomography revealed a papillary carcinoma within a juxtathyroidal thyroglossal duct cyst. After surgery, the initial diagnosis was papillary thyroid carcinoma. After correlation with the computed tomography, the diagnosis was revised to a papillary thyroid carcinoma plus a follicular adenoma in a juxtathyroidal thyroglossal duct cyst. This case demonstrates the need for close clinical and radiographic correlation in such a complex case.     

Thyroid tuberculosis diagnosed as papillary thyroid carcinoma with fever of unknown origin

Thyroid tuberculosis is a rare disease, very few cases have been reported. It is difficult to diagnose because of no typical characteristics. We report on a patient who underwent surgery for suspected thyroid carcinoma, but who was then diagnosed with thyroid tuberculosis. The patient was a woman in her 70s. She had been diagnosed with chronic renal failure and had been on peritoneal dialysis. She complained of fever and a painful left anterior neck swelling. Computed tomography showed thyroid tumor with cervical lymph node swelling, ultrasound-guided fine needle aspiration cytology was suspected for papillary thyroid carcinoma. We performed surgery to confirm the diagnosis and determine treatment. Procedures for thyroid carcinoma were followed, including left lobectomy of the thyroid gland, central lymph node dissection and right cervical lymph node resection. Pathological examination found no malignant findings in the thyroid tissue but did find a granulation layer even in the right cervical lymph node. Tuberculosis-specific IFN-γ assay was positive, we diagnosed thyroid and cervical lymph node tuberculosis. Postoperatively, the neck pain and fever improved, she was treated as an outpatient with antituberculosis drugs therapy. Thyroid tuberculosis must be considered in patients with immunocompromised, such as this patient, who was on peritoneal dialysis.     

The role of positron emission tomography/computed tomography in the management of recurrent papillary thyroid carcinoma

OBJECTIVES/HYPOTHESIS: The aim of the study was to evaluate the role of combined positron emission tomography/computed tomography (PET/CT) fusion imaging in the detection and management of recurrent papillary thyroid cancer. STUDY DESIGN: A retrospective analysis of 33 patients with suspected recurrent papillary thyroid carcinoma who had undergone PET/CT was performed. PET/CT was compared with standard imaging techniques in each patient to determine whether PET/CT contributed to the therapeutic management plan. Histopathological findings were correlated to PET/CT in patients who underwent surgery. METHODS: The senior author reviewed the charts of 33 patients with recurrent papillary thyroid carcinoma to determine the impact PET/CT had on management. PET/CT was compared with conventional imaging results. In surgical patients, PET/CT was compared with histopathological findings to determine its sensitivity, specificity, accuracy, positive predictive value, and negative predictive value. RESULTS: In 67% of the cases (22 of 33), PET/CT supplied additional information that altered or confirmed the management plan. Twenty of 33 patients underwent surgery with 36 sites assessed by histopathological analysis. PET/CT correlated with histopathological findings in 25 of 36 distinct anatomical sites, with an accuracy of 70%. The sensitivity of PET/CT in identifying recurrence was found to be 66%, with a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 27%. CONCLUSION: Combined PET/CT fusion scanning was most useful in the detection and management of recurrent papillary thyroid cancer in patients who had average thyroglobulin levels greater than 10 ng/mL and when the tumor no longer concentrated radioactive iodine. In 100% of the cases in which PET/CT localized a region suspicious for malignancy, histopathological analysis confirmed the results. When PET/CT is positive, it is a powerful tool for predicting exact locations of recurrent papillary thyroid cancer, thus making it a reliable guide for surgical planning. PET/CT is a supplement to conventional imaging and fine-needle aspiration in the workup of recurrent papillary thyroid cancer. A negative finding on PET/CT is not sufficiently reliable to preclude further investigation and treatment.     

Large cell neuroendocrine carcinoma of the parotid gland: case report and literature review

A 74-year-old male presented with a large polinodular mass in the neck. Fine needle aspiration cytology (FNAC) showed an undifferentiated large cell carcinoma. Computed tomography (CT) showed a large parotid mass with multiple satelite nodules. The remaining radiological studies were normal. Radical parotidectomy was performed. The tumor was a large cell carcinoma with neuroendocrine features and positive immunostain for neuroendocrine markers. The patient received postoperative radiotherapy and was free of tumor eight months later. Only four cases of large cell neuroendocrine carcinoma (LCNEC) of the salivary gland have been communicated. All of them have involved the parotid gland. This tumor presents in elderly patients as a large infiltrating parotid mass. Fine needle aspiration cytology serves to recognize the carcinoma, but it fails in recognizing the neuroendocrine features of the tumor. The histopathological features of this tumor are the same as in other organs. Chromogranin and synaptophysin are useful immunohistochemical markers. A primary location of the tumor in another organ, specially the lung, should be ruled out. Surgery is the main treatment modality and can be complemented with postoperative radiotherapy. The prognosis seems to be poor. More studies are needed to better define the therapeutical alternatives and prognostic factors of these rare tumors.

Transoral videolaryngoscopic surgery for papillary carcinoma arising in lingual thyroid

Carcinoma arising in lingual thyroid is an extremely rare entity accounting for only 1% of all reported ectopic thyroids. Here, we report a case of carcinoma arising in lingual thyroid, which has been successfully managed by transoral resection and bilateral neck dissections.A lingual mass 4-cm in diameter with calcification was incidentally detected by computed tomography at medical check-up. No thyroid tissue was observed in normal position. Ultrasound examination showed bilateral multiple lymphadenopathies. Fine needle aspiration biopsy from lymph node in his right neck was diagnosed as Class III and thyroglobulin level of the specimen was 459 ng/ml. Due to the difficulty in performing FNA of the lingual masses, right neck dissection was performed in advance for diagnostic purpose. Pathological examination showed existence of large and small follicular thyroid tissues in several lymph nodes, suggesting lymph node metastasis from thyroid carcinoma. Two months after the initial surgery, video-assisted transoral resection of lingual thyroid with simultaneous left neck dissection was performed. Postoperative course was uneventful. Papillary carcinoma was found in the lingual thyroid and thyroid tissues were also found in left cervical lymph nodes.Video-assisted transoral resection was useful for the treatment of thyroid cancer arising in lingual thyroid.     

CT-scan prediction of thyroid cartilage invasion for early laryngeal squamous cell carcinoma

Treatment choice for laryngeal cancer may be influenced by the diagnosis of thyroid cartilage invasion on preoperative computed tomography (CT). Our objective was to determine the predictive value of CT for thyroid cartilage invasion in early- to mid-stage laryngeal cancer. Retrospective study (1992–2008) of laryngeal squamous cell carcinoma treated with open partial laryngectomy and resection of at least part of the thyroid cartilage. Previous laser surgery, radiation therapy, chemotherapy and second primaries were excluded. CT prediction of thyroid cartilage invasion was determined by specialized radiologists. Tumor characteristics and pathologic thyroid cartilage invasion were compared to the radiologic assessment. 236 patients were treated by vertical (20 %), supracricoid (67 %) or supraglottic partial laryngectomy (13 %) for tumors staged cT1 (26 %), cT2 (55 %), and cT3 (19 %). The thyroid cartilage was invaded on pathology in 19 cases (8 %). CT’s sensitivity was 10.5 %, specificity 94 %, positive predictive value 13 %, and negative predictive value 92 %. CT correctly predicted thyroid cartilage invasion in only two cases for an overall accuracy of 87 %. Among the false-positive CT’s, tumors involving the anterior commissure were significantly over-represented (61.5 % vs. 27 %, p = .004). Tumors with decreased vocal fold (VF) mobility were significantly over-represented in the group of false-negatives (41 vs. 13 %, p = .0035). Preoperative CT was not effective in predicting thyroid cartilage invasion in these early- to mid-stage lesions, overestimating cartilage invasion for AC lesions and underestimating invasion for lesions with decreased VF mobility.     

Hashimoto's thyroiditis and carcinoma of the thyroid: Optimal management

Several authors have noted a high incidence of thyroid carcinoma in patients with Hashimoto's thyroiditis (HT), and some have even considered HT a premalignant condition. The authors evaluated all patients with surgically proven HT at Beth Israel Medical Center in New York from 1985 through 1990. Of these 48 patients, 8 (17%) had thyroid carcinoma in addition to HT. No statistically significant difference between patients with and without concurrent carcinoma was noted in the percentage of patients with a dominant mass, irregular thyromegaly, compressive symptoms, suspicious fine needle aspiration biopsies (FNABs), or a cold nodule on thyroid scintigraphy. However, patients with neither a positive FNAB nor a cold nodule were much less likely to have carcinoma than patients with one or both of these tests positive (0% vs. 26%, P±.05). A management scheme for patients with HT is proposed to adequately and efficiently evaluate and treat patients for concurrent thyroid carcinoma.     

Cerebellar and pulmonary metastases from papillary thyroid carcinoma. Report of a case

We are reporting the clinical case of a male who was diagnosed as papillary thyroid carcinoma with cervical, cerebellar and lung metastases. Although in theory it was a well differentiated tumour and slow progression with a good prognosis, there was a very aggressive spread in our patient up to his death. We decided not to operate him and send him to the Oncology Service for chemotherapy that was unsuccessful. The intracranial metastases due to papillary thyroid carcinoma are very uncommon (about 1%) on the contrary of cervical ones, but their behaviour is more aggressive and frequently associated to other metastases on bone or lung.     

Clinical study on papillary thyroid carcinoma presenting with lymph node metastasi

Papillary thyroid carcinoma (PTC) may metastasize to cervical lymph nodes. It is, however, uncommon for a palpable neck node alone to lead to the diagnosis of this disease when it is not apparent at presentation. Standard treatment for such cases has not yet been established. We retrospectively analyzed clinical courses in 8 patients with thyroid papillary carcinoma presenting with palpable lymph node metastasis at Hokkaido University Hospital between 1990 and 2003. Three had high thyrogloblin in cervical cystic lesions, leading to the diagnosis of PTC with lymph node metastasis. In 4, PTC was diagnosed by pathological examination of cervical lymph nodes initially diagnosed as lateral cervical cysts. Preoperative examination did not indicate PTC within the gland in any case. All 8 were alive at the last visit after follow-up from 23 to 150 months (mean: 78 months). Total thyroidectomy was done on 4 and thyroid lobectomy on 3. Pathological examination of resected thyroid glands confirmed multifocal papillary carcinoma from 4 mm to 15 mm in diameter. Six underwent unilateral neck dissection and 1 chose bilateral dissection. The other patient received no additional surgery on either the thyroid or neck after the single enlarged lymph node initially diagnosed as a lateral cervical cyst was resected. Postoperative radioiodine treatment was done in 2 undergoing total thyroidectomy. Recurrence in the cervical area were observed in 1 whose neck dissection was insufficient. Based on these observations, we concluded that patients who undergo thyroid lobectomy and adequate neck dissection may enjoy longer survival than those treated with total thyroidectomy without sacrificing thyroid and parathyroid function. We therefore propose a prospective study on the effectiveness of thyroid lobectomy with neck dissection including positive nodes in patients with occult PTC presenting with lymph node metastasis.     

Metastatic disease of bronchial carcinoma in a thyroid nodule: a case report

Metastatic spread of solid tumors to the thyroid is a rare finding in patients with thyroid nodules. The most frequent sites of the primary tumor include the kidney, breast and lung. Work up of patients with a cold thyroid nodule and a history of cancer should therefore rule out other metastasizing cancer or recurrence of the previous tumor using fine-needle aspiration of the thyroid mass. We report the case of a 64-year-old male with metastatic spread of a bronchial carcinoma to the thyroid and the management of this case.     

Pre-operative embolisation of the thyroid artery in a patient with a large papillary carcinoma of the thyroid

Objective: To demonstrate the usefulness of pre-operative selective embolisation of the thyroid arteries in an unusual case with a large, vascular thyroid tumour. Case report: A 29-year-old man presented with a large papillary carcinoma of the thyroid (weighing approximately 300?g on palpation) with extension to the mediastinum and compression of the trachea. A computed tomography scan of the neck and thorax revealed a large tumour the solid part of which was enhanced after contrast medium application, indicating a substantial vascular supply. Pre-operative selective embolisation of both superior thyroid arteries and one inferior thyroid artery, using gelatin sponge particles, was performed 4 days before surgery, under conventional angiography. After selective embolisation of these thyroid arteries, the patient experienced mild anterior neck pain and mild fever. This procedure allowed a significant reduction in blood perfusion to the tumour, which facilitated its surgical removal without blood transfusion. Conclusion: Pre-operative selective embolisation of both superior thyroid arteries and one inferior thyroid artery may be an effective, minimally invasive procedure for patients with a large, vascular thyroid tumour.     

A rare case of hyperfunctioning papillary carcinoma of the thyroid gland

We report a rare case of hyperfunctioning papillary carcinoma of the thyroid. A 32-year-old man was referred to our hospital for the treatment of a painless mass in the left neck, which had been detected on routine physical check-up. Cervical ultrasonography and computed tomography showed a solid tumor with calcification in the left lobe of the thyroid gland. Serum examinations demonstrated hyperthyroidism with a high level of thyroglobulin. Fine needle aspiration biopsy revealed a cytological diagnosis of class II. Tc-99m scintigraphy showed a hot nodule in the left lobe, which implied that the tumor was a hyperfunctioning thyroid tumor. Left lobectomy of the thyroid gland was performed to treat the hyperfunctioning tumor. Postoperative pathological examinations revealed a follicular variant papillary carcinoma. Postoperative thyroid function became within the normal range. Although hyperfunctioning thyroid carcinomas are rare, it is important to correctly diagnose them and to perform appropriate surgical interventions.     

Preoperative cytology with molecular analysis to help guide surgery for pediatric thyroid nodules

Objectives

To discuss the use of molecular mutation analysis in the surgical management of pediatric thyroid nodules.

Methods

This study is a case series with retrospective chart review performed at a tertiary children's hospital. Pediatric patients who presented to the Children's Hospital of Pittsburgh of UPMC with a thyroid nodule and had subsequent fine needle aspiration with positive molecular mutation between November 2009 and February 2012 were identified and charts were reviewed. Patient demographics, presenting signs, lab results, pathologic findings, and surgical outcomes were collected.

Results

5 pediatric patients with positive molecular mutation studies on preoperative FNA were identified. FNA results were categorized as follows: suspicious for follicular neoplasm (n = 2), suspicious for malignant cells (n = 1), and positive for malignant cells (n = 2). The following molecular mutations were identified: BRAF (V600E) (n = 2), PAX8/PPARγ (n = 1), HRAS (n = 1), and RET/PTC (n = 1). A total thyroidectomy was performed on each patient. In all cases the final pathology was positive for malignancy (papillary thyroid carcinoma (PTC), n = 3; follicular variant of PTC, n = 2). Three of five patients had transient postsurgical hypocalcemia. There were no other postoperative complications.

Conclusions

This series provides evidence that preoperative FNA with reflex molecular testing in pediatric thyroid nodules can help guide surgical decision making, reduce the need for repeat surgeries, and diminish the risk of complications from a staged procedure.
