Dermatomyositis with Calcinosis Cutis Universalis.

Area of Science:

• Pediatric Rheumatology
• Dermatology
• Medical Case Study

Background:

• Dermatomyositis is a rare idiopathic inflammatory myopathy affecting children.
• Calcinosis cutis universalis is a significant complication characterized by widespread calcium deposition.
• This case highlights the challenges in managing complex pediatric autoimmune conditions.

Observation:

• An eleven-year-old girl presented with classic dermatomyositis signs: heliotrope rash and Gottron's papules.
• Extensive subcutaneous calcifications were noted over the shoulders, pelvic girdle, and proximal extremities.
• Muscle wasting and contractures indicated significant disease burden.

Findings:

• Diagnosis was confirmed through biochemical assays, histopathology, and electromyography.
• The patient exhibited severe manifestations of both dermatomyositis and calcinosis cutis universalis.
• Histopathological examination revealed characteristic inflammatory and calcific changes.

Implications:

• Early and aggressive treatment is crucial for managing severe pediatric dermatomyositis.
• High-dose corticosteroid therapy, alongside supportive measures, can lead to functional improvement.
• This case underscores the importance of multidisciplinary care for children with rare autoimmune diseases and their complications.
