Cranial fasciitis

Abstract

A 26-year-old man presented with an 18-month history of a subcutaneous mass on his forehead that occurred shortly after being struck by a blunt object. Histopathologic examination showed a proliferation of bland spindle cells and a collagenous stroma that was consistent with cranial fasciitis. Cranial fasciitis, which is a variant of nodular fasciitis, is a benign fibroblastic neoplasm that overlies the skull and often is associated with trauma. Although its rapid onset may give the clinical impression of a malignant condition, cranial fasciitis typically is cured by simple excision without further sequelae.
