I ntroduction:Inflammatory Myopathies are a group of acquired diseases in which most important finding is subacute progressing symmetrical proximal muscle weakness and fatigue with mononuclear cells infiltration in the muscle tissue along with degeneration and regeneration of muscle fibers and elevation of the muscle enzymes. In nonspecific myositis, the important point is the prominent infiltration of the macrophages rather than lymphocytes in the muscle tissue, and intact fibers with infiltration are less common. Materials and Methods: In this retrospective and descriptive study, files and pathological slides of patients with myositis, hospitalized in the neurologic ward of Ghaem hospital or outpatients visited the neuropathology center from 1996 to 2006, were again evaluated. This study was approved by the local ethics. Results:Overall, 39 patients with inflammatory myopathy diagnosis admitted during this period, of which were 56.4 males and 43.6 females. The average age of the women and men was 31 and 35.5 years respectively. Dysphagia was see in 33.3, tenderness and muscle pain in 41, Reynoud�s phenomen in 7.6, elevated muscle enzymes in 82, lung involvement in 5.1, heart involvement in 5.1, positive ANA in 5.1 and elevated ESR in 53.8 of the patients. Thirty-nine patients were evaluated in the neuropathology ward and amoung this group 36 cases had nonspecific myositis and 3 patients had polymyositis. Conclusion:In this study it is shown that polymyositis is a rare disease, and the presence of inflammation in muscle biopsy, elevated muscle enzymes and weakness of girdle muscles are not necessary for the polymyositis diagnosis confirmation. However, most of these cases are nonspecific myositis which will not respond to corticosteroid therapy.
