| Summary: | Conjunctival nevi are benign, heterogenous tumors that uncommonly arise from the lacrimal caruncle and plica semilunaris. We present a case of a patient diagnosed and managed for an unusual, pigmented nevus of the left caruncle involving the plica. An 84-year-old woman presented with a rapidly growing, pigmented lesion in her left nasal canthus. Examination demonstrated a raised, dark, pigmented area arising from the left caruncle and seeming to involve the plica semilunaris without scleral extension. The lesion was completely excised for histopathology, which confirmed the diagnosis of a compound nevus with pigment incontinence. Given the unfavorable anatomical position and prognostic significance in the case of malignancy, pigmented caruncular lesions should be thoroughly investigated with a low threshold for surgical removal.
