MERRF syndrome presenting with multiple symmetric lipomatosis in a Japanese patient.

Myoclonic epilepsy with ragged red fibers (MERRF), also called Fukuhara's disease, is sometimes accompanied by the rare symptom of multiple symmetric lipomatosis (MSL). MSL associated with MERRF has been reported mainly in Caucasians; such cases have not been reported in Japanese patients. We report the case of a 59-year-old Japanese woman with MERRF syndrome associated with A-->G substitution at nucleotide 8,344 of mtDNA. This case suggests that differences in lifestyle and gene polymorphism among races may be related to the prevalence of MSL due to mitochondrial abnormality, and that mitochondrial abnormalities should be considered as a cause of MSL even in Japanese patients.
