We report the rare case of a male patient (age 42) who presented with more than 11 trichilemmal cysts (TC) and a proliferating trichilemmal cyst (PTC) on his head. The PTC was a large keratinized protuberant lesion of an open cyst with a continual wall to the epidermis, and no such PTC case has yet been reported in Japan. We suppose that the PTC developed from the TC after one of the cysts had ruptured due to an injury.
