Juvenile Dermatomyositis: A Case Report and Review of Literature

Area of Science:

• Pediatric Rheumatology
• Dermatology
• Immunology

Background:

• Juvenile dermatomyositis (JDM) is a rare autoimmune disease affecting children.
• It primarily targets the skin and musculoskeletal system, leading to characteristic rashes and muscle weakness.
• Histological findings include lymphocytic vascular inflammation and endothelial swelling.

Observation:

• A 10-year-old girl of Indian origin presented with symptoms consistent with JDM.
• Clinical manifestations included characteristic skin findings and proximal muscle weakness.
• Histopathological examination confirmed the diagnosis.

Findings:

• The patient exhibited classical clinical signs such as Gottron papules and heliotrope rash.
• Symmetric proximal muscle weakness was a key feature.
• Biopsy revealed lymphocytic vascular inflammation and endothelial swelling, confirming JDM.

Implications:

• This case underscores the importance of recognizing classical JDM presentations in pediatric patients.
• Early diagnosis and management are crucial for improving outcomes in JDM.
• Understanding the ethnic background may offer insights into disease prevalence and presentation.
