Abstract

PURPOSE
To report a case of medial canthal tendon fibroma, a rarely observed tumor at the eye or ocular adnexa. CASE SUMMARY: A 47-year-old female visited our clinic with a two-year history of a hard mass in the medial canthal region. On examination, a 7 x 5 mm2 sized, hard and unmovable subcutaneous mass was palpated. The mass was slowly enlarging and the patient had no symptoms including tearing or pain. To confirm the diagnosis, a total excision of the mass was performed under local anesthesia. The tumor was a well-demarcated, 7 x 5 x 2 mm3 sized, white oval mass. The histopathologic examination of the specimen revealed dense collagen bundles with scattered fibroblasts. Based on these findings, the lesion was diagnosed as a fibroma. Although rare, fibromas should be included in the differential diagnosis of medial canthal tumors.
