Fibroma of the medial canthal area: a case report.
A 47-year-old women presented with a mass on the right medial canthal area for 10 years. On examination, an 18 × 12-mm sized, hard, unmovable subcutaneous mass was palpated. The tear meniscus was high, but the lacrimal outflow system was patent when irrigated. The mass was surgically excised. It was well-demarcated with a whitish pearl-like appearance and located between the orbicularis muscle and the anterior lacrimal crest. A silicone tube was intubated simultaneously. The microscopic examination of the specimen revealed dense collagen with scattered fibroblasts without mitosis or atypism, and stained positively for vimentin and negatively for S-100 and CD 34. Based on these findings, the lesion was diagnosed as a fibroma. No sign of recurrence was observed over 6 months of follow up. Although rare, fibroma should be included in the differential diagnosis of medial canthal tumors. Complete surgical excision offers a curative method of management.
