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.
A 28-year-old male presented with a large conjunctival lobulated, nonpulsatile, red vascular lesion involving a large part of the temporal quadrant of the left globe. There was no proptosis or globe displacement, but the left eye abduction was limited. T2-weighted magnetic resonance imaging scan of the brain and orbit revealed an extensive contrast-enhancing lobulated lesion in the left half of the face involving the upper lip, cheek, oral cavity, extraconal space of left orbit, and nasal cavity. He underwent surgical excision of the conjunctival lesion with amniotic membrane reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
