Abstract
Inflammatory myopathies (IM) or myositis are a heterogeneous group of muscle diseases of rare occurrence. Such diseases are characterized by inflammation of the different components of muscle tissue, which can occur either in isolation or, more commonly, as part of a systemic disorder. Immune-mediated necrotizing myopathies (IMNM) are a type of autoimmune myopathy characterized by proximal muscle weakness, myofiber necrosis with minimal inflammatory cell infiltrate on muscle biopsy and infrequent extramuscular involvement.
Even though there are clinical and histopathological similarities. The spectrum of inflammatory myopathies is considerably variable. Therefore, the performance of complementary studies is essential for the proper identification of the IM subtype to contribute accurately on treatment so determine the better prognosis).
The present article shows the case of a young 29 years old, with no personal and family history background of autoimmune disease and no relevant pathological back-ground. The patient consulted the medical ward of the Institution with pain, functional impairment of upper and lower extremities, muscle weakness mainly located in the pectoral girdle area and, although to a lesser degree, in the pelvic girdle area.
