Conjunctival Trichodiscoma of the Lower Eyelid.

Trichodiscomas are benign tumors of the skin which develop around a hair follicle. They usually present on the face, neck, or trunk region. The authors report a rare case of a 63-year-old man who presented with a tumor on the left lower eyelid that was histologically proven to be a trichodiscoma of conjunctival origin.Trichodiscomas are benign tumors of the skin appendage which develop around a hair follicle. Although conjunctival hair follicles are rudimentary and do not give rise to hair, rarely a benign proliferation of these cells can result in trichodiscoma of the conjunctiva.
