What other diseases/conditions are associated with "cox negative fibers on muscle biopsy" besides mitochondrial diseases?
A doctor has provided 1 answer
Complex issues. Best: look them up yourself. E.g. https://www.google.com/search?q=muscle+biopsy+COX+negative+fibers, https://scholar.google.com/scholar?q=muscle+biopsy+COX+negative+fibers & http://emedicine.medscape.com/article/1847877-overview would be good places to begin.

My muscle biopsy has mild neurogenic-type changes, striated muscle fibers with excess fiber size variation, few angulated atrophic fibers, and scattered pyknotic nuclear clumps. They are doing histochemical analysis now will this give me a diagnosis?
