CONTEXT Lymphoepithelial cyst of the pancreas is a rare benign lesion that should be managed conservatively. Similarity has been described between lymphoepithelial cyst and a branchial cyst of the neck. CASE REPORT We report a 58-year-old man presenting with left sided abdominal pain initially thought to be renal colic. CT of the abdomen revealed a 3.5 cm lesion in the pancreatic tail. A lapa...

CONTEXT Lymphoepithelial cysts are rare benign lesions of the pancreas. Endoscopic ultrasound guided fine needle aspiration (FNA) has reportedly been helpful in reaching a diagnosis of lymphoepithelial cyst. In cases where it may be difficult to obtain a diagnosis using FNA a histological sample may be obtained using EUS guided Trucut biopsy. CASE REPORTS We describe two cases of lymphoepithe...

Lymphoepithelial cysts of the pancreas are extremely rare, benign, nonneoplastic cysts that may simulate pseudocysts or cystic neoplasm of the pancreas. Endosonographic and cytologic features of pancreatic lymphoepithelial cysts are poorly characterized because of their rarity. However, appropriate prospective diagnosis of pancreatic lymphoepithelial cysts using endoscopic ultrasound-guided fin...

BACKGROUND Lymphoepithelial cyst of the pancreas is a rare lesion of undetermined pathogenesis that had been documented almost exclusively in males. The literature on this entity is limited to reports of single or a small number of cases. METHODS The case we described herein was compared with a total of 36 cases reported elsewhere. RESULTS The 37 cases of lymphoepithelial cyst of the pancre...

lymphoepithelial cyst of oral cavity is a rare cystic lesion that presents as an asymptomatic submucosal mass and is usually discovered during routine dental examinations. the site most commonly affected is floor of the mouth and tonsillar involvement seems to be very rare. multiple lymphoepithelial cysts have been reported in parotid of hiv positive patients however in oral cavity they usually...

CONTEXT Lymphoepithelial cysts with sebaceous glands of the pancreas are extremely rare, with only 7 cases, including this case, published in English literature. CASE REPORT We herein present the case of a 67-year-old Asian man who underwent a resection of a lymphoepithelial cyst of the pancreas during the follow up care for lung cancer. Fourteen years previously he underwent a right lower lo...

A rare case of lymphoepithelial cyst formed in the piriform sinus of the hypopharynx is reported. Histopathological examination revealed a lymphoepithelial cyst. It was removed by laryngomicrosurgical technique using a side-opened direct laryngoscope. Because this cyst was wide-based on the antero-medial region in the right piriform sinus of the hypopharynx, the mucous membrane around the cyst ...

CONTEXT Lymphoepithelial cysts of the pancreas are a rare disease of true pancreatic cysts, the cause of which is unknown. The differential diagnosis is broad and includes many benign and malignant cystic lesions of the pancreas and surrounding organs. A combination of imaging modalities and fine needle aspiration might narrow the differential diagnosis. However, the final diagnosis can only be...

The oral lymphoepithelial cyst is an uncommon lesion in children with rather distinct clinical features. This case report describes the pertinent characteristics of this entity, involving the floor of the mouth in a 4 year-old boy. (Pediatr Dent 22:422-423, 2000) The oral lymphoepithelial cyst (LEC) is an uncommon developmental lesion that is frequently an incidental finding during a routine de...
