[Intra-osseous epidermoid cyst].

In contrast to epidermoid cysts under the skin of the palm and the fingers, intraosseous epidermoid cysts are very rare. They present in the terminal phalanges of the fingers and are posttraumatic in nature. Their clinical and X-ray presentation is similar to enchondroma and pathological fractures do occur. When operating, one must remove the capsule to prevent recurrence. Bone grafting is usually not necessary after adequate curettage. Two typical cases are presented.
