Generalized hypertrophic myopathy associated with chorioretinal dystrophy and struma lymphomatosa--a case report.

A case is reported of a girl suffering from generalized hypertrophic myopathy and chorioretinal dystrophy since early infancy. A muscle biopsy taken at age seven revealed a general enlargement of the muscle fibers with a concomitant extensive degeneration of myofibrils. At age fourteen, the patient developed a struma lymphomatosa (Hashimoto). This report is the first describing an association of these three diseases.
