Pigmented terminal hair cysts within an intradermal melanocytic naevus.

The combination of melanocytic naevi and cysts of adnexal or epithelial origin has been described previously. Herein we describe a case of intradermal melanocytic naevus containing pigmented terminal hair cysts, a rare variant of epithelial cysts. Our observation suggests that pigmented follicular cysts and combined cystic-melanocytic lesions may be attributed to follicular occlusion.
