Trichilemmal Cyst of the Bulbar Conjunctiva: A Rare Presentation
A 55-year-old female from South India of Dravidian race presented with a history of gradually progressive, painless swelling in the left bulbar conjunctiva adjacent to the nasal limbus of 3 years duration. It was not associated with redness, discharge or blurring of vision. There was no history of trauma or history of any surgery performed in the past. There was no significant family history. On clinical examination, there was a nodular mass adjacent to the nasal limbus of left eye measuring 5 mm × 5 mm, fixed to the underlying tissue, non-tender, lying within the pterygium [Figures and ]. The transillumination test was negative. Examination of the rest of the anterior and posterior segment was unremarkable. The right eye was unremarkable. A fold of subconjunctival tissue extending from the swelling to the caruncle was observed during wide excision biopsy of the lesion. The specimen was sent for histopathological examination.\nHistopathology indicated the presence of sebaceous material.\nMicroscopic examination showed a cyst lined by stratified squamous epithelium with the absence of granular cell layer, focal basal cell hyperplasia, and flakes of keratin within the cyst [Figures –]. A diagnosis of a conjunctival trichilemmal cyst was made based on the histopathological findings.
