Benign acute childhood myositis (BACM) is a rare transient clinical condition that mainly affects preschool and school age children, preceded by a viral illness, with an excellent prognosis and no functional sequelae. Objective: To describe the clinical and laboratory features of BACM. Study design: Retrospective cross-sectional study. Study setting: Department of Pediatrics, KVG Medical College and Hospital. Methodology: Nineteen children of benign acute childhood myositis were seen during September 2016- January 2017. Inclusion criteria: Children presenting with preceding history of fever, cough, cold, headache/myalgia followed by acute onset of pain in both legs and difficulty in walking and unable to bear weight. Exclusion criteria: Children with neuromuscular disorders, children with altered sensorium, recent intramuscular injection, history of vigorous exercise and history of trauma. Results: Out of nineteen children, the mean age of presentation was 7.5 years, predominantly affecting males 68%(n=13) with male: female ratio of 2.1:1. Leucopenia was seen in 32%(n=6) with neutropenia in 26%(n=5) with reactive lymphocytes in all patients (100%). Creatinine phosphokinase was elevated in all children with mean of 1892U/L. Dengue serology was negative in all patients. Mean duration of time of clinical recovery from the onset of pain was 3.32days (3.32+0.48 days) with mean duration of hospital stay of 4.5days. There was no significant association noted between CPK levels and duration of clinical recovery(p=0.087). The outcome of therapy was mainly supportive with complete clinical recovery. Conclusion: BACM is a benign entity with a characteristic clinical presentation that can be managed with supportive treatment, avoiding unnecessary diagnostic investigations.
