CONTEXT Lymphoepithelial cyst of the pancreas is a rare benign lesion which often presents as an incidental radiological finding, but may cause symptoms, such as abdominal pain and nausea. It can occur at any location in the pancreas. The differential diagnosis includes primary splenic cysts, pseudocysts, mucinous cystic neoplasms of the pancreas, left adrenal cysts, duplication cysts and retro...

A case of amyloid goiter in a 73-year-old man with systemic amyloidosis complicating long lasting rheumatoid arthritis is reported. The thyroid gland was massively infiltrated with amyloid and contained foci of fat tissue and epithelial solid cell nests. Incidentally, a cyst lined by squamous epithelium, with small amount of lymphocytes in the subepithelial stroma was found. This cyst fulfilled...

Lymphoepithelial cyst (LEC) of the pancreas is an extremely rare, benign pancreatic cystic lesion that is difficult to differentiate preoperatively from other cystic pancreatic lesions. LEC may have malignant potential. Here, we describe a case of LEC of the pancreas - initially suspected to be a mucinous cyst neoplasm - in an elderly man presenting with abdominal pain, who went on to have a di...

We report a case of lymphoepithelial cyst of the pancreas with non-specific elevation of CA 19.9 and CEA. Pre-operative diagnosis by conventional means proved elusive, and only surgical resection and histopathology revealed the diagnosis. The origin and diagnosis are discussed by literature review.

Thyroglossal duct cysts (TDCs) are cervical cysts occurring in approximately 7% of the population, mainly during childhood. The cyst usually presents itself as a painless, asymptomatic midline swelling below the hyoid bone. Differential diagnosis involves branchial cleft cyst, lymphoepithelial cyst, thyroid gland lesions, ranula and lymphadenopathy (of various etiologies). Sonogram (ultrasound)...
