title: [Proliferative myositis].
abstract: A 86-year-old female patient is reported with myositis proliferans according to the criteria described by Enzinger and Dulcey (1967). This disease, first described by Kern (1960), impressed as a painful, firm and immovable tumor of almost 3 cm in size situated at the upper lip of our patient. Myositis proliferans can simulate a sarcoma, histologically and clinically; therefore, this disease shall be introduced to the dermatologic literature avoiding unnecessary invasive treatment. There is a relationship to fasciitis nodularis; a clinical and histological differentiation is possible as in our patient.
