Summary and Conclusions: Medical literature concerning neoplastic change within a pilonidal sinus is reviewed briefly and a case of epidermoid carcinoma involving a pilonidal sinus is presented. Diagnosis, pathology and treatment are discussed.

Epidermoid carcinoma occurs rarely in pilonidal disease and usually it is a complication of a long-standing, draining sinus. The lesion generally grows slowly, may extend locally or into the regional lymph nodes, and there may be generalized metastasis. If diagnosed early, wide excision and primary skin grafting of the invaded area may be performed, with a reasonably good chance of a desirable result.
