| Popis: | Nudular fasciitis is an uncommon benign proliferative lesion in the head and neck, and is extremely rare in the auricle. A case of nodular fasciitis arising in the auricle of 53-year-old man is reported by immunohistochemical and electron microscopical studies. Initially, he had noticed a' small painless nodule on the posterior side of right auricle, and it grew up rapidly in size over 2 months. A biopsy revealed nodular fasciitis. This lesion was resected totally with the auricular cartilage. Histological examination revealed proliferation of spindle-shaped cells and immunohistochemical-positive staining was observed with actin, and focally positive staining was seen with vimentin. Electron microscopically some tumor cells contained dilated rough endoplasmic reticulum and myofilament-like bundles in cytoplasm. |
