Abstract

Dermatomyofibroma represents a recently-described, relatively rare, distinct cutaneous mesenchymal neoplasm, which shows a myofibroblastic line of differentiation. It presents as a solitary, slow-growing, nodular or plaque-like lesion, and commonly occurs on the shoulder and axilla area of young female patients. Histopathologically, the tumor is a non-encapsulated, plaque-like lesion, composed of fascicles of monomorphic spindle cells predominantly oriented parallel to the skin surface. We report a 21-year-old female with a solitary nodule on the shoulder, which showed histological and immunohistochemical features diagnostic of dermatomyofibroma.
