Calcinosis of the flexor and extensor tendons in dermatomyositis--case report

Area of Science:

• Pediatric Rheumatology
• Hand Surgery
• Dermatology

Background:

• Dermatomyositis is an idiopathic inflammatory myopathy.
• Calcinosis, the deposition of calcium in soft tissues, can be a complication of dermatomyositis.
• Flexion contractures in pediatric patients can lead to significant functional impairment.

Observation:

• A young female child presented with dermatomyositis.
• She developed a flexion contracture in her dominant hand.
• This contracture was secondary to extensive calcinosis affecting the flexor tendons.

Findings:

• Surgical intervention, specifically flexor tenosynovectomy, was performed.
• The procedure involved the careful removal of calcium deposits.
• Post-operative assessment indicated improved range of motion and function of the affected hand.

Implications:

• This case highlights a potential surgical approach for managing calcinosis-induced contractures in pediatric dermatomyositis.
• Flexor tenosynovectomy can be an effective treatment to restore hand function.
• Early intervention may prevent long-term disability associated with such complications.
