Histological abnormalities in muscle from patients with certain types of fibrositis

Lancet. 1986 Apr 5;1(8484):755-7. doi: 10.1016/s0140-6736(86)91779-4.


In muscle biopsy specimens from fibrositis patients and healthy subjects no differences in electrical charges on the contractile proteins were detected with a microelectrode technique. However, microscopical examination of fibrositis muscle showed muscle fibres connected by a network of reticular or elastic fibres which are absent in normal muscle and which may be the cause of the disorder.
