Abstract

Trichilemmal cyst is a benign tumor that originates from the external root sheath. It usually occurs on the scalp, but rarely on the face, neck and trunk. A 41-year-old man presented with a skin-colored non-tender subcutaneous nodule on his abdomen. The histopathologic findings of the lesion showed a well demarcated cystic mass with trichilemmal keratinization in the dermis. It was diagnosed as a trichilemmal cyst and then it was totally excised. We report here on a case of trichilemmal cyst on the abdomen, which is known to be an unusual site for this type of lesion.
