Ophthalmological examination revealed a pea-sized mass in the palpebral conjunctiva of the left lower eyelid. Ulcerative keratitis and blepharospasm were detected due to the irritation caused by the mass. Fluorescein staining was positive and the Schirmer tear test result was 13 mm/min. No other masses were detected in other parts of the patient’s body, and its general condition was good. The mass was removed surgically and was interpreted as histiocytic sarcoma. During a three-year, post-operative follow-up period, no recurrence of the mass was observed.eninfo:eu-repo/semantics/openAccessHistiocytic SarcomaArticle93313613710.21825/vdt.91528Q4N/A
