Epidermoid Inclusion Cysts of the Hand

ABSTRACT: Epidermoid inclusion cysts occur second only to ganglions in terms of  tumefaction presentations in the hand. This review describes 60 such lesions and reviews the  clinical presentation, diagnosis, and treatment. The epidermoid inclusion cyst probably arises  from some traumatic event that drives epithelial cells into the subcutaneous tissues where they s urvive, grow,and produce keratin.
