ABSTRACT
Epidermal cysts are common skin lesions, but they occur rarely in the oral cavity. Very few cases have been reported in the literature, and, here we present one such rare case of epidermal cyst of the base of the tongue in a 24 year male patient. The patient presented with the complain of swelling below the tongue which was gradually increasing in size for the past one and half year with difficulty in speech, mastication and closure of mouth. Intraoral examination revealed presence of large solitary swelling in the sublingual region more towards the right side. It was non-tender, fluctuant soft and fixed to the underlying mucosa having no secondary changes. Aspiration cytology was performed which was consistent with the diagnosis of Epidermal cyst.
