We describe a case of limb girdle muscular dystrophy with associated
myasthenia gravis. This association has not been previously noted in the
literature. The unusual feature of the case was that symptoms coexisted for
several years before a correct diagnosis was made. The diagnosis was based
on the clinical picture and the results of the muscle biopsy and
electrophysiologic testing. This case serves to illustrate the fact that a
separate problem should be considered when the clinical picture is not
compatible with the underlying diagnosis.
