[focal myositis]

This case report describes focal myositis , a rare inflammatory pseudotumorous disease previously not mentioned in the surgical literature . Most often a single muscle of the upper or lower extremity is affected . Usually the diagnostic process and treatment require a long time . We present a useful diagnostic cascade and a surgical therapy , which allows the histological differentiation between malignant and inflammatory disease . Even after partial resection of the tumor , the prognosis of focal myositis is excellent .
