[Teutschländer disease. A rare benign differential diagnosis in proliferating space-occupying lesions of soft tissues].

Tumoral calcinosis is a very rare benign soft tissue calcification. It occurs in all age-groups and prefers the shoulder, hip and elbow region as localisation. In most cases, local pain is the leading symptom. The aetiology remains unclear, so far, however, a certain connection to an imbalance of the calcium-/phosphate homeostasis is proposed. The adequate therapy is the complete surgical removal. Our presented case describes an extended occurrence at an unusual localisation and discusses characteristic signs in contrast of the differential diagnoses.
