Symmetrical muscle contractures in tumorous sarcoidosis: report of a case.

A 25-year-old woman had symmetrical contractures of the gastrocnemii with a large firm swelling in both medial heads. The contractures insidiously increased over the previous six months. Roentgenograms of the chest showed hilar lymphadenopathy but investigations were otherwise negative. Biopsy showed this to be tumorous sarcoidosis. Both tendoachilles were lengthened. Spontaneous regression of the abnormal muscle masses subsequently occurred without further treatment. Tumorous sarcoidosis is a rare entity, and there have been very few previous reports of muscle contractures having occurred associated with sarcoidosis.
