(LEC) of the pancreas is rare true pancreatic cyst.
Cystic lesions were mucocele/retention cyst in 7 cases, lymphoepithelial cyst
in 1, ranula (1) and keratin cyst in 1.

Moreover, differential diagnosis should be made of smears with noncancerous and cancerous lesions containing lymphocytic cells, namely chronic inflammation of the salivary gland, reactive inflammation of lymph nodes, lymphoepithelial cyst
, lateral cyst of the neck, Warthin's tumor and malignant lymphoma.
and epidermoid cyst of the accessory spleen in the pancreas.
1, 2) LEL has been variably designated as Sjogren-like syndrome, benign lymphoepithelial lesion, cystic lymphoepithelial lesion, HIV salivary gland disease and lymphoepithelial cyst
The most common lesion is the benign lymphoepithelial cyst
Less common branchial cleft anomalies include a first BCC, or a parotid lymphoepithelial cyst
, arising from a tract extending from the external auditory canal through the parotid to the submandibular triangle (Figure 5).
is a rare benign cystic lesion of the pancreas.
Aspirates of lymphoepithelial cyst
reveal squamous cells, keratinous materials, lymphocytes, histiocytes, and cholesterol crystals.
In our series of cystic lesions, the combination of thick extracellular material (which in retrospect most likely represented keratinous debris) and gastrointestinal contamination led to the false impression of mucus-producing cystic neoplasm with an aspirate from a lymphoepithelial cyst
The combination of cystic lesion with a predominant lymphoid component arising in a background of lymphocytic thyroiditis can be mistaken for a benign lymphoepithelial cyst
