Abstract:
Eleven years after an arthroscopic procedure, a benign tumor of the knee located beneath the scar where the outflow canula was placed was excised. Histomorphological evaluation determined the diagnosis of an epidermoid cyst. This is the first case reported in the literature of an epidermoid cyst occurring after an arthroscopic operation. The previous epidermoid cysts reported were found after trauma or after dermal grafting for epithelium implantation.
