후경부 섬유종 1예

Abstract

Nuchal fibromas are rare, benign fibrous proliferations characterized by hypocellular dense collagen in the dermis and the subcutaneous fat layer. Nuchal fibromas usually develop in the posterior neck as a solitary, soft tissue mass. Herein, we report a case of a nuchal fibroma presenting on the posterior neck of a 60-year-old male. An excisional biopsy was done and showed haphazardly-arranged, dense collagen infiltration throughout the dermis and the subcutaneous fat layer. Moreover, fat lobules, adnexas and nerve fibers were entrapped by collagen bundle infiltrations. Dermatologists should include nuchal fibrma in the differential diagnosis of patients with a posterior neck mass.
