Trichoblastic carcinoma of the scalp with rippled pattern.

Trichoblastic carcinoma (TC) is a rare type of malignancy which is derived from the hair follicles. In this paper, we report a case with TC on the scalp characterized with rippled pattern. There have been reports of rippled pattern in trichoblastomas, sebaceomas, and basal cell carcinomas. To the best of our knowledge, this is the first case in the literature to report a rippled pattern in TCs.
