Ectopic tooth in maxillary sinus compressing the nasolacrimal canal: A case report

Rationale:Ectopic tooth is tooth erupting out of normal anatomical position. Ectopic tooth can occur in different positions, such as maxillary sinus and nasal cavity. In this article, we present a rare case of an ectopic tooth with a dentigerous cyst in the maxillary sinus compressing the nasolacrimal canal.Patient concerns:An 8-year-old girl presented with a 2-month history of spontaneous lacrimation in her right eye. When she wept, more tear shed from her right eye than that from the left one. Computed tomographic (CT) imaging showed a huge low-density image containing a tooth in the maxillary sinus in her right maxilla; the right nasolacrimal canal vanished due to the compression of the ectopic tooth.Diagnoses:Ectopic tooth with dentigerous cyst of right maxilla, and obstruction of nasolacrimal ductInterventions:The patient underwent nasal endoscopic maxillary sinus cystectomy.Outcomes:The patient recovered well after cystectomy and has been symptom-free.Lessons:The unique finding is that this is the first report about ectopic tooth compressing the nasolacrimal canal and inducing spontaneous lacrimation. Treatment: aspect: surgery under endoscope is a minimally invasive approach to ectopic tooth.     

Malignant prolactinoma: case report and review of the literature

Pituitary carcinomas are extremely rare. In general, the initial clinical, biochemical, and histological characteristics are of minimal utility in distinguishing benign adenomas from pituitary carcinomas. We describe a 63-year-old woman with a macroprolactinoma, who presented with diplopia and blurred vision. This unusual initial presentation and the subsequent aggressive clinical course, with diffuse local and distant intramedullary metastases, prompted us in retrospect to make a detailed analysis of the therapeutic interventions and histology. In addition, we reviewed all available literature on published cases of malignant prolactinoma and detailed their epidemiological, clinical, and histopathological characteristics. In brief, it is postulated that pituitary carcinomas arise from the transformation of initially large, but benign, adenomas. Unusual and/or atypical clinical manifestations appear to occur more frequently. In vivo, the development of dopamine agonist resistance in invasive macroprolactinoma is indicative of malignancy and should prompt the clinician to perform a biopsy of the tumor. For pituitary tumors that exhibit high mitotic activity, increased Ki-67 and/or p53 immunoreactivity, it may be useful to denote these tumors as 'atypical' prolactinomas to raise the possibility of future malignant development.

Ectopic gastric pancreatic cancer: report of a case

It is very rare for ectopic pancreas to become cancerous. We herein report on a case of ectopic pancreatic cancer developed in the stomach. A neoplastic lesion was detected in the pyloric part in an upper GIS of a 76-year-old female, requiring biopsy, but because it was classified as Group I, it was observed temporarily. Following blood collection after approximately 2 years, the CA19-9 increased from 177.5 to 279.5, so a GIS was again performed. Although the pyloric part of the stomach became more stenosed than before, it was still considered Group I disease based on biopsy findings. When EUS was performed, the tumor appeared as a submucosal tumor, and was thus suspected as GIST. In an abdominal CT, a neoplastic lesion with a clear boundary was observed in the pylorus, as was an enlarged lymph node in the hepatoduodenal ligament. Therefore malignancy could not be ruled out, and a gastrectomy on the pylorus side, lymph node dissection (D2), and cholecystectomy were performed. The tumor was a submucosal tumor covered by a coherent mucosa. According to histopathological findings, it was diagnosed as ectopic pancreatic cancer developed in the ectopic pancreas (Heinrich type II), consisting of acinar tissue and capillary tubes. Thus ectopic pancreas should be considered in the differential diagnosis of gastric submucosal tumors. Regarding surgery for ectopic pancreas, it is considered necessary to establish a treatment policy by making an immediate pathological diagnosis with sufficient consideration of the possibility of malignancy.     

Septic complications to sphenoidal sinus infection.

Sphenoid sinusitis is an uncommon infection, but an early diagnosis and appropriate treatment is important because of its serious complications. We report 4 patients (28, 28, 37 and 28 years old) admitted to a department of infectious diseases with meningitis, sepsis and orbital cellulitis as complications of acute sphenoidal cavity infection. The cases illustrate the value of computed tomography (CT) scan of the sphenoid sinus in the evaluation of patients with clinical features suspicious of sphenoid sinusitis.

Ectopic enterobiasis: a case report and review.

Enterobius vermicularis ('pinworm') is rarely found outside the gastro-intestinal tract. We describe a case of extra-intestinal pinworm abscess associated with an inguinal hernia in an adult. A brief review of the literature is given and possible mechanisms of tissue invasion are discussed.     

Ectopic pancreas presenting with intractable diarrhea: case report

Ectopic pancreas is an uncommon congenital anomaly, which is usually found incidentally in clinical practice. It presents with nonspecific gastrointestinal symptoms like epigastric pain and dyspepsia and rarely with the clinical findings of obstructive jaundice or intestinal obstruction, or it may mimic gastrointestinal system cancer. Herein, we describe a case of ectopic pancreas in the duodenum, which was the cause of the intractable diarrhea. In our patient, upper gastrointestinal endoscopy and endoscopic ultrasonography revealed a 1.5 cm submucosal lesion, which was umbilicated centrally with a normal in appearance overlying mucosa. Endoscopic biopsy of the lesion was normal. Pathological examination of the lesion after surgical excision was compatible with ectopic pancreas. After total excision of the lesion, the clinical findings of the patient normalized. Ectopic pancreas presenting with diarrhea has not been reported previously in the literature.     

Ectopic thyroid mass in the right ventricle: A case report

Ectopic thyroid is a rare congenital embryonic anomaly. Ectopic thyroid tissue can be located anywhere during its descent, but it is found primarily at the base of the tongue and in the mediastinum. It is very rarely found in the heart. Here, we report a rare case of cardiac ectopic thyroid tissue in a 53‐year‐old woman who presented with chest pain. Echocardiography revealed an intracardiac mass that was removed successfully. Histopathology confirmed that the mass was thyroid tissue without malignancy.

Aspergillosis of the maxillary sinus: review and case report

A case of non-invasive aspergillosis affecting the maxillary sinus is presented. Reference is made to its possible aetiology (spores introduced to the antrum at the time of a root canal overfilling with a zinc oxide paste). A review is presented and the management of the case is described.     

Ectopic lingual thyroid tissue and acquired hypothyroidism: case report

Ectopic thyroid tissue with thyroid gland in its normal location is an extremely rare phenomenon. We present a case of a 38-year-old woman who was referred to our hospital with symptoms of hypothyroidism. Thyroid hormone measurement revealed clinical hypothyroidism with elevated anti-thyroid antibodies, neck ultrasonography showed a small tissue with the characteristic of Hashimoto thyroiditis, while the scintigraphy demonstrated only a lingual thyroid. Treatment consisted in L-thyroxine replacement to the euthyroid state. We reviewed the literature with respect to the embryological background and the clinical management of such cases.     

异位甲状旁腺癌肺转移一例报告

原发性甲状旁腺功能亢进症（primary perparathyroidism，PHPT）在我国尚无明确的发病率统计，不过，近年来随着诊断技术水平的提高，发病例数有逐步增多的趋势。本例甲状旁腺病变较为特殊，现结合有关文献资料，报告如下。     

Ectopic intrathyroidal thymoma: a case report and review.

Ectopic intrathyroidal thymomas are an exceedingly rare clinical entity that can be challenging to diagnose. This report describes a 39-year-old Japanese woman who presented with prominent left-sided thyroid enlargement that was thought to be a dominant thyroid nodule by ultrasound. Two fine-needle aspiration biopsies showed an atypical lymphoid proliferation that was suspicious for although not diagnostic of a low-grade lymphoma. A diagnosis of ectopic intrathyroidal thymoma was made only after appropriate histopathologic assessment of the surgical specimen.     

Ectopic variceal bleeding after hepatobiliary surgery: A case report

Rationale:Jejunal varices are rare in portal hypertension and are often difficult to diagnose and treat. Herein, we present a case of gastrointestinal bleeding due to jejunal varices after hepatobiliary surgery.Patient concerns:A 69-year-old man presented with recurrent massive gastrointestinal bleeding. He underwent partial right hepatectomy and cholangiojejunostomy 2 years prior to the first onset of bleeding. Two sessions of endoscopic vessel ligation for esophageal varices were performed afterwards, and hematemesis resolved completely, but massive melena still recurred during the following 5 years.Diagnosis:The patient was diagnosed with jejunal varices caused by portal venous stenosis after hepatobiliary surgery.Intervention:Portal venous angioplasty using balloon dilation and stent implantation was performed.Outcomes:After the intervention procedure, the patient did not experience any onset of gastrointestinal bleeding during follow-up.Lessons:Hepatopancreatobiliary could lead to the formation of jejunal varices. The combined use of capsule endoscopy, contrast-enhanced computed tomography, and sometimes portal venography is a promising strategy to search for jejunal varices. Transcatheter angioplasty appears to be a safe and effective method for treatment of jejunal varices in certain appropriate cases.
