Differently sized subcutaneously localized painless tumor masses.

Some authors question the autonomy of the clinical picture. A fibroblastic/myofibroblastic differentiation can be found in various cutaneous sarcomas. A close histogenetic relationship between fibrosarcoma, malignant fibrous histiocytoma and myofibroblastic sarcoma is assumed.
