RESUMO
INTRODUCTION: Juvenile dermatomyositis (JDM), a rare multisystemic autoimmune disease of unknown cause, leads to chronic inflammation of both striated and smooth muscles. SARS - Co V2 virus infection in children generally remain asymptomatic. However, in some children it leads to a detailed immunological response named as multisystem inflammatory syndrome in children (MIS-C). Post recovery, occasionally, children are susceptible to other autoimmune disorders. CASE PRESENTATION: Our case post MIS-C developed JDM. 8-year-old malnourished child developed proximal myopathy of both upper and lower limbs post recovery from COVID 19. His disease severity increased within a short span of time and he went on to develop contractures and deformity of both upper and lower limbs. He developed an uncommon complication of JDM in form of highgrade non-Hodgkin's lymphoma. CONCLUSION: This case highlights the importance of long-term complications of COVID-19 in children which would gradually evolve in the next few years.
