NEUROGENIC MUSCULAR ATROPHY SIMULATING FACIOSCAPULOHUMERAL MUSCULAR DYSTROPHY - WITH PARTICULAR REFERENCE TO HETEROGENEITY OF KUGELBERG-WELANDER DISEASE

Two cases of Kugelberg-Welander (K-W) disease of unusual clinical presentation are described. One was a 25-year-old man with a pattern of neurogenic muscular atrophy simulating facioscapulohumeral muscular dystrophy, the other was a 24-year-old man with neurogenic muscular atrophy simulating scapulohumeral muscular dystrophy. These cases differ in certain clinical respects from the classical form of K-W disease which simulates limb-girdle muscular dystrophy. K-W disease can possibly be divided into several subgroups from the clinical and genetic aspects, by an analogy with the various forms of muscular dystrophy; i.e. the disease is considered to be clinically and genetically heterogeneous. © 1969.
