A 18-year-old femalepatient presented with a left conjunctival mass, which had been enlarging for 1 month. The tumor was located at the corner of the conjunctiva of the left eye. The size of the tumor was 1 mm in width and 1.5 mm in height, and tenderness and redness were not observed. There was no history of trauma, but bilateral upper lid blepharoplasty was performed 2 months prior to her visit. Excision of a conjunctival mass was performed and there was no evidence of involvement of the sclera or peripheral conjunctiva around the mass. We performed immunohistochemistry and PCR for human herpes virus 8 (HHV8). Immunohistochemistry was positive for S-100 and negative for smooth muscleactin and HHV8. The mass was myofibroblastic in nature and the histopathological features and clinical findings of this case were diagnosed as nodular fasciitis with the features as described above. There was no recurrence for 4 months after removal of the mass.
