[Fibromatosis colli--a benign tumor of the neck in diagnosis and therapy].

Fibromatosis colli is a benign tumor of infancy, and although prognosis is usually good, it is the most frequent cause of congenital torticollis. The clinical picture, sonography, or, if required, CT scans, permit a clear diagnosis. Invasive diagnostic and therapeutic measures should be avoided and restricted to those cases, where a malignancy is suspected with good reason or where local complications due to bulk shifts and compression are anticipated. Even after the usually spontaneous remission of the tumor torticollis may develop later on so that accompanying exercise therapy should be provided from infancy to school age.
