Giant epidermoid cyst on the forefoot.

BACKGROUND

Epidermoid cysts are the most common cysts of the skin, usually appearing in the hairy regions. However, epidermoid cysts on the non-hair-bearing areas, such as the palms and the soles, are rare and seldom reach a size of more than 5 cm in diameter.

OBJECTIVE

To present a patient with an epidermoid cyst of unusual location and size.

METHODS

A 23-year-old woman with a painless tumorlike mass on her right forefoot was examined and the mass was excised.

RESULTS

The 6.5 cm x 5.5 cm x 5.5 cm mass was totally excised. Histologic diagnosis was reported as an epidermoid cyst.

CONCLUSION

An original case regarding an unusual location and size of an epidermoid cyst is presented.
