Abstract
-
Trichilemmal cyst is known to be a kind of keratinous cyst with lining cells showing trichilemmal keratinization. About 90% of trichilemmal cysts occur on the scalp. They are only rarely found on the face, neck and trunk. A 25-year-old man had a skin-colored nontender nodule on his left leg. Clinically, we were considered epidermal cyst. However, histopathologic examination showed that there was abrupt keratinization without granular layer, which was compatible with those of trichilemmal cyst.
