Abstract
Nodular fasciitis is a benign, idiopathic condition that can simulate both benign and malignant neoplasms. In adults, it generally occurs in the subcutaneous or superficial fascia of the trunk or upper extremities; occurrence in the periorbital region is far less common. We describe a case of a 16-year-old male with a 4-month history of a nodular, non-tender, progressively enlarging mass of the superotemporal periorbita. Histopathologic analysis of the excisional biopsy demonstrated nodular fasciitis, confirmed by molecular cytogenetic analysis that showed rearrangement of USP6.
