Abstract:
Panniculitis is a rarely reported manifestation of juvenile dermatomyositis. The 3 previously reported cases of juvenile dermatomyositis and panniculitis were attributed to flare of underlying disease, rather than infection, and were treated with increased immunosuppression. Here we describe a patient with juvenile dermatomyositis who developed panniculitis secondary to Staphylococcus aureus. Patients with juvenile dermatomyositis and panniculitis should have extensive testing for infectious etiologies before increasing their immunosuppressive regimens.
Insights
Panniculitis in juvenile dermatomyositis is rare. A case suggests Staphylococcus aureus infection, not disease flare, necessitating infection testing before immunosuppression.
Area of Science:
- Pediatric Rheumatology
- Dermatology
- Infectious Diseases
Background:
- Juvenile dermatomyositis (JDM) is a rare autoimmune disease causing muscle inflammation and skin rashes.
- Panniculitis, inflammation of subcutaneous fat, is an uncommon presentation of JDM.
Observation:
- Previously reported JDM-associated panniculitis cases were linked to disease flares and treated with immunosuppression.
- This study details a patient with JDM who developed panniculitis due to Staphylococcus aureus infection.
Findings:
- The patient's panniculitis was a secondary infection, not a manifestation of JDM flare.
- Prompt identification of infectious etiology is crucial for appropriate management.
Implications:
- Patients with JDM and panniculitis require thorough infectious workup before escalating immunosuppressive therapy.
- This case highlights the importance of considering infection in JDM patients presenting with panniculitis.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
