Pigmented Spindle Cell Nevus of the Palpebral Conjunctiva

ABSTRACT

PURPOSE: Pigmented spindle cell tumor of the palpebral conjunctiva is very rare, and most of the tumors arise at extremities or trunk. To our best knowledge, no case has been repoted in Korea so far. We report one case of pigmented spindle cell nevus with literature review. METHODS: A 21 years-old male patient complaining of mass on the left upper palpebral conjunctiva underwent excisional biopsy with minimal touch technique. RESULTS: On histopathologic examination, the mass consisted of small, regular and spindle cells with pigmentation. And HMB-45 and CD-34 stains were negative, while S-100 stain was weakly positive. CONCLUSIONS: We report one case of pigmented spindle cell nevus as the first case in Korea.
