Lymphoepithelial cyst. Lymphoepithelial cysts of the salivary glands. The cyst may be covered by squamous epithelium. An extensive The head and neck sites are the salivary The cytology of the AIDS-related lymphoepithelial cyst is the same, but you must be aware of the presence of high virus content Lymphoepithelial cyst of the pancreas (LECP) is an exceedingly rare The cytologic The cytology The cytology of the AIDS-related lymphoepithelial cyst is the same, but you must be aware of the presence of high virus content of the fluid in these cases (large amount of infectious viral particles). Fine needle aspiration of cyst fluid using this modality (EUS-FNA) has provided a means of further characterizing a lesion in an effort to determine best management. Lymphoepithelial cysts are rare pancreatic lesions of undetermined pathogenesis. Benign lymphoepithelial cyst, also known, as branchial cyst is an infrequent lesion usually occurs in the parotid gland or the lateral cervical area including lymph nodes. Lymphoepithelial cyst (LEC) of the pancreas is a rare, non-neoplastic lesion composed of keratinizing squamous epithelial cells and lymphoid tissue [].Prospective diagnosis of LEC remains challenging due to paucity of data in the literature, its non-specific imaging, and the presence of cytologic features that overlap with other cystic pancreatic lesions. Abstract. Sporadic lymphoepithelial cyst may result from cystic dilation of ducts within intraparotid or periparotid lymph node or branchial cleft remnants. HIV They occur predominantly in men in the 5th and 6th Modern Pathology, 15(5), 492501. Histologic and cytologic features Fourteen cases of surgically excised lymphoepithelial cysts (13 from the parotid gland and 1 from the Lymphoepithelial cyst of the pancreas is exceedingly rare, and only Lymphoepithelial cysts (LECs) are extremely rare, non-neoplastic cysts of the pancreas that have a mature squamous cell lining and subepithelial lymphoid stroma (Adsay et al. The oral lymphoepithelial cyst (LEC) is a rare, soft-tissue, developmental cyst, initially presented by Gold in 1962 as a branchial cleft cyst. Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and KEY WORDS: Lyphoepithelial cyst, sub-mandibular gland, benign neck lesion malignant transformation Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. Pancreatic lymphoepithelial cysts are rare, benign, non-neoplastic unilocular or multilocular cystic lesions. (2002). The fine-needle aspiration cytology (FNAC) features that have been reported for HIV-associated BLL include squamous Btow KW. EUS-FNA-based cytology has shown in a meta-analysis 6 a sensitivity Parotid lymphoepithelial cysts in human immunodeficiency virus: a review - Volume 127 Issue 11 However, cyst fluid chemical and cytologic features in less common types of pancreatic cysts have not been reported. This is the first case report of lymphoepithelial cyst from India. 4.

(FNA) cytology or core biopsy) coupled with biochemical/tumor marker studies are increasingly being used to increase the diagnostic accuracy [13, 14, 15]. Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and of PCL. Lymphoepithelial cysts (LECs) of the pancreas are benign lesions with no malignant potential. Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. Lymphoepithelial cysts of the pancreas: An EUS case series. They are also called Branchial cyst. The cytologic features of LECs have been described only in a handful of case reports and may overlap with both benign and malignant pancreatic tumors. Lymphoepithelial cysts (LECs) of the pancreas are rare, benign pancreatic cysts comprising approximately 0.5% of all pancreatic cysts. Benign lymphoepithelial cyst (BLC), also known as branchial cyst, is an infrequent lesion usually occurs in the parotid gland or the lateral cervical area including but pus can also be there if the cyst is infected. Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and radiographically. A case of LECP clinically and radiographically mimicking a pseudocyst in a 44yrold man is described and preoperative fineneedle aspiration cytology was instrumental in correctly identifying the lesion as a benign true cyst, thus permitting appropriate surgical management by local resection. Lymphoepithelial cysts of the salivary glands. Histologic and cytologic features Fourteen cases of surgically excised lymphoepithelial cysts (13 from the parotid gland and 1 from the submandibular gland) were reviewed for diagnostic histologic features. They showed squamous epithelium-lined cysts within lymph nodes. The literature on this entity is limited to case reports or small series. Results: Eighty Case description: The cervical lymphoepithelial or branchial cleft cyst usually presents as a unilateral, soft-tissue fluctuant swelling that typically appears in the lateral aspect of the The cytologic features of LECs have been described only in a handful of case reports and may overlap with both benign and malignant pancreatic tumors. Cyst fluid cytology and chemical features in a case of lymphoepithelial cyst of the pancreas: A rare and difficult preoperative diagnosis. The imaging (EUS) with fine-needle aspiration (FNA) cytopathology may help diagnose LECs,[5] but cyst cytology may be difficult to interpret due to contamination of the aspirate by intestinal tissue with mucinous and glandular epithelium. 328-330.

Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and radiographically. The cytologic features of LECs have been described only in a handful of case reports and may overlap with both benign and malignant pancreatic tumors. Lymphoepithelial cysts of the pancreas: A report of 12 cases and a review of the literature. Epidermoid cysts in intrapancreatic accessory spleens would be difficult to distinguish from LECs based on cyst fluid cytology alone but on surgical would show red Adsay, N. V., et al. They are also called Branchial cyst. We describe a case of 66 year male, incidentally diagnosed as lymphoepithelial cyst of pancreas that was managed by enucleation. Lymphoepithelial cysts (LECs) of the pancreas are rare, benign pancreatic cysts comprising approximately 0.5% of all pancreatic cysts. Nasr J, Sanders M, Fasanella K, et al. The cyst may be covered by squamous epithelium. Lymphoepithelial cysts (LEC) of the pancreas are rare benign lesions that can be misdiagnosed as pancreatic masses or cystic neoplasms. Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and radiographically. Diagn Cytopathol, 21 (1999), pp. Lymphoepithelial cyst is seen as a well-defined, low attenuation mass, attached to the pancreas and not associated with pancreatic duct dilatation. Lymphoepithelial cysts are uncommon benign oral cavity cysts Essential features Oral lymphoepithelial cysts are most common in the lateral tongue and floor of mouth There is a heterogeneous population of lymphatic cells in the background of homogeneous cystic fluid. Abstract and Figures. Comparative study of the effect of antiretroviral therapy on benign lymphoepithelial cyst of parotid glands and ranulas in HIV-positive patients. Lymphoepithelial cysts (LECs) are rare non-neoplastic lesions that can appear as a complex cyst or a mass in the pancreas.
