Malignant mixed tumor of the larynx: a case report

Malignant mixed tumour (MMT), which is a salivary gland tumour, is the malignant form of pleomorphic adenoma. Although the tumour can also originate from the minor salivary glands throughout the submucosa in the head and neck region, laryngeal involvement is quite rare. An additional case of laryngeal MMT presented in a forty-five year old man, and the diagnostic, immunohistochemical (S-100, actin, vimentin, epithelial membrane antigen) and therapeutic procedures were presented.     

Laser excision of a typical carcinoid tumor of the larynx: a case report

Neuroendocrine carcinomas of the larynx include a range of rare tumors which have variable biologic behavior, affecting treatment and prognosis. Among these, typical carcinoid tumors are the least common type. Prognosis of typical carcinoid tumor is better than atypical carcinoid tumor and small cell carcinoma of the larynx. Conservation surgery is the preferred treatment modality. Transoral CO2 laser surgery can be a good alternative for appropriate cases because of the functional results and less morbidity. In this article, a 71-year-old female presented with complaints of feeling a mass during swallowing. Fiberoptic examination of the larynx revealed a mass located on the right aryepiglottic fold and biopsy revealed the tumor as a typical carcinoid tumor. We describe CO2 laser excision of a typical carcinoid tumor of the larynx in this case report.     

Typical carcinoid tumor of the larynx occurring with otalgia: a case report

Neuroendocrine neoplasms of the larynx comprise a rare group of tumors that have a controversial history with regard to their classification. The World Health Organization categorizes these tumors as typical carcinoids, atypical carcinoids, small-cell neuroendocrine carcinomas, and paragangliomas. Atypical carcinoids and small-cell neuroendocrine carcinomas are the more common. Only 13 cases of typical carcinoid have been reported. Local excision is sufficient for typical carcinoids and paragangliomas, but atypical carcinoids require neck dissection because of their tendency to metastasize. Small-cell neuroendocrine carcinomas are not cured by local excision, and these patients have the worst prognosis (5-year survival: 5%); their treatment is limited to chemo- and radiotherapy. Because of these variations in tumor behavior and treatment, it is essential that otolaryngologists and pathologists to be able to correctly identify the specific type of tumor in order to optimize patient treatment and survival. We report a case of typical carcinoid and review the pertinent literature on this subject.     

Schwannoma of the larynx: a case report

Neurogenic tumors of the larynx are rare. We report a case of supraglottic schwannoma in a 59-year-old woman. We excised the tumor via a lateral thyrotomy approach.     

Neurilemmoma of the larynx: a case report

Neuromas or Schwannomas are extremely rare among tumors of the larynx. They are Schwann cell tumors that can be difficult to distinguish from neurofibromas. They present usually as supraglottic masses, since they may arise from the internal branch of the superior laryngeal nerve. Nuclear magnetic resonance imaging is the best diagnostic technique, conferring a high degree of suspicion. We present an exceptional case of a laryngeal neuroma, with a very long evolution, a large tumor volume, dyspnea and vocal cord fixation, with complete resolution through an external approach following surgical removal. The difficulties encountered with its pathological and clinical diagnosis are discussed as well as a review of the literature.     

Giant cell tumor of the larynx: a case report and review of the literature

Giant cell tumors are benign tumors commonly found in the long bones. Rarely, they may occur in the larynx, and patients with such tumors may present with hoarseness and anterior neck swelling. Since Wessely reported the first case of laryngeal giant cell tumor in 1940, 30 cases have been identified. Herein, we present a case of a 31-year-old man with giant cell tumor of the larynx successfully treated via the hemilaryngectomy approach.

True carcinosarcoma of the larynx: a case report

A case of true carcinosarcoma of the larynx occurring in a 55-year-old male is reported. The two components of this very rare tumour are pleomorphic rhabdomyosarcoma and squamous cell carcinoma. A review of the literature has revealed only two authentic cases of true carcinosarcomas.     

Angiomyolipoma of the larynx: case report

The authors present the report of the first ever case of angiomyolipoma arising in the larynx. The tumor was found in a 61-year-old man and was resected through laryngofissure. Histopathologic examination of the tumor revealed numerous smooth muscle cells, mature adipose tissue and numerous thin and large irregular vessels. Both histological and immunohistochemical findings were typical for tumors of the mucocutaneous angiomyolipoma group.     

Schwannoma of the larynx: case report

Neurogenous tumours of the larynx are extremely uncommon. We present a rare case of schwannoma of the larynx. Clinical findings are presented together with computed tomography (CT) and magnetic resonance images. The tumour was located in the right aryepiglottic fold of the larynx. CT showed a well defined and hypodense mass extending from the right aryepiglottic fold to the right vocal cord. The patient underwent an excision of the mass through a lateral thyrotomy and the tumour was completely removed. The diagnosis and treatment of this tumour are discussed.

Glandular hamartoma of the larynx: report of a case

Glandular hamartoma is an extremely rare congenital malformation of the larynx. Presenting symptoms result from airways obstruction and may include slowly rising respiratory distress, stridor, changes in voice, eating and activity levels. Management consists in local mass excision with a good functional result and prognosis. Recurrences are usually associated with incomplete removal. We present a 3-month-old infant with a history of stridor and respiratory distress caused by a firm 0.4cm wide and 1.4cm long mass arising in the supraglottic region and detected with endoscopic approach. The lesion was excised endoscopically with an uneventful postoperative course and an excellent long-term prognosis. Histopathologically the lesion consisted of mature tissues with abnormal growth and disorganized architecture, chiefly composed of mature glandular structures, smooth muscular fibers, mature fat, surrounded by fibrous stroma and covered by typical squamous epithelium. The aim of our report is to underline how this condition must be considered by physicians, paediatricians and anaesthetists as an important cause of airway obstruction.

Adult giant hemangioma of the larynx: a case report

We report a giant hemangioma that extended from the mesopharynx to the larynx in an adult.

The patient was a 39-year-old woman who had demonstrated an asymptomatic pharyngeal hemangioma since she was 1 year-old.

She developed vertigo and consulted a hospital at the age of 39. During screening by head MRI for the diagnosis of the vertigo, hemangioma of the laryngopharynx was detected. She was referred to Osaka National Hospital for further examination. Her subjective symptoms were dyspnoea in the lower left lateral-position.

On observation by nasopharyngolaryngovideoscope, a giant hemangioma was diagnosed in the left mesopharynx expanding into the larynx. On MRI study, hemangioma widely extended to the right posterior wall at the mesopharynx level.

Since we were concerned about risk of choking if the hemangioma of the larynx were left untreated, we recommended surgery. Under the general anesthesia, hemangioma of the larynx was light-coagulated by KTP laser through tracheotomy.

The postoperative-course has been good and at 9 months postoperatively, there was no progression of hemangioma.
