[Prominent conjunctival tumor].

The case of a 57-year-old woman with a rapidly growing unpigmented conjunctival tumor is presented. Despite the clinical appearance the histology surprisingly confirmed a malignant melanoma of the conjunctiva. Various phenotypes and the rareness of this disease complicate a clinical diagnosis. Therapeutically, a complete excision of the tumor including a safety margin, adjuvant topical chemotherapy and closely monitored follow-up are crucial.
