Mitochondrial disease with myopathy

ABSTRACT

Mitochondrial disease with myopathy is a rare progressive disease which affects more than one system of the body. It can be diagnosed only by muscle biopsy showing ragged red fiber cells [RRFs] that requires special [trichrome] staining, often not available in routine histopathology laboratories. There is no specific treatment or cure for the condition. A case, confirmed by biopsy, is reported in a 42-year-old Qatari female suffering from previously undiagnosed chronic progressive weakness and possibly related hyperthyroidism
