Benign lymphoepithelial cyst

AbstractBenign 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. It occurs due to
the process of lymphocyte-induced cystic ductular dilatation and is always diagnosed
postoperatively by histopathological examination. The cyst is usually lined by squamous
epithelium surrounded by lymphoid stroma. Although unusual, two cases diagnosed within
two months are reported here. Both patients were male but the locations of the lesions were
different. One lesion was within cervical lymph node and the other was near the parotid gland.
Both the lesions were surgically excised and diagnosed histopathologically as benign
lymphoepithelial cyst. Its frequent association with HIV infected patients since last two decades
has made it a significant lesion now-a-days. In this regard along with reported two cases brief
literature reviews including origin, diagnosis and treatment are discussed.
Key words: Benign lymphoepithelial cyst; parotid; lymph node; HIV infected patients.
