A Rare Case of Tropical Myositis

Pyomyositis is a primary infection of skeletal muscles usually caused by staphylococcus aureus. This infectious disease is endemic in tropical areas and sporadic in temperate climates. It mainly affects immunocompromised patients like patients with AIDS, leukemia, and diabetes mellitus, etc. The incidence of pyomyositis is increasing worldwide with rise in prevalence of patients infected with HIV virus. The disease is neglected initially due to nonspecific clinical features. Further evolution of disease is usually associated with fever, septic shock and inflammatory involvement of large muscles of the lower extremity. The diagnosis of the responsible agent is established by blood culture and surgical or radio-guided puncture. Treatment includes antibiotics and surgical drainage. Our case showed such a typical presentation of myositis without any pus formation, which responded to standard treatment. We would like to report such a rare case at our institute.
