Background: Benign acute childhood myositis (BACM) is a rare, transient, and self-limited inflammatory condition of the skeletal muscle that usually occurs after a viral infection. The present study was conducted to assess benign acute childhood myositis in a tertiary care centre. Materials & Methods: 40 children with benign acute myositis of both genderswas included. Parameters such as clinical features, laboratory investigations, number of hospitalization and median length of stay was recorded. Results: Out of 40 patients, males were 22 and females were 18.BACM was single in 35 and recurrent in 5. Clinical featureswas fever in 34, gait abnormality in 25 and muscle pain in 37. White cell count showed neutrophils was 2045/μL and lymphocytes was 1906/μL. Viral studies showed influenza A in 11, influenza B in 6, adenovirus in 2, coxsackievirus in 4, echovirus in 3 and mycoplasma in 2 patients. Hospitalization was seen in 34 and median length of stay was 4.5days. Creatine kinase was 1480IU/L. The difference was significant (P< 0.05). Conclusion: Most of the patientshad single type of benign acute childhood myositis. Common clinical featureswas fever, gait abnormality and muscle pain.
