Benign lymphoepithelial cyst (BLC), also called as branchial cyst, is a rare lesion usually occurs in the parotid gland or sometime lateral cervical area. Most likely the etiology could be due to the process of lymphocyte‐induced cystic ductular dilatation and the final diagnosis can be made postoperatively by histopathological examination (HPE), but here in this article we try to give some clinical characteristics which can be helpful to arrive at a diagnosis. 55‐year‐old male reported to our department 1 year ago, with a soft, nontender, gradually increasing, sessile localized swelling involving the right parotid gland since 3 to 4 months of size 3.5 cm × 3.5 cm × 2 cm at the time of presentation with normal Stensen’s duct and facial nerve function. Biochemistry indicated high protein content of aspirated fluid. Cyst enucleation was done with nonincidental healing. HPE of excisional tissue revealed it to be BLC.
