Summary
Idiopathic plantar hidradenitis is a rare cause of tender foot nodules in children, often mimicking other conditions. Dermatopathology confirms the diagnosis, distinguishing it from similar pediatric plantar lesions.
Area of Science:
- Dermatology
- Pediatric Pathology
- Vaccine Adverse Events
Background:
- Plantar nodules in children present diagnostic challenges due to similar morphologies across various conditions.
- Dermatopathology is crucial for definitive diagnosis of pediatric plantar lesions.
- Idiopathic plantar hidradenitis is a recently described entity.
Observation:
- A 12-year-old experienced tender, red plantar nodules post-hepatitis B vaccination.
- Clinical differential diagnoses included juvenile plantar erythema nodosum, insect bites, urticaria, and plantar hidradenitis.
- Lesions resolved spontaneously within 10 days without recurrence.
Findings:
- Skin biopsy revealed dense neutrophilic infiltrate and abscess formation around eccrine glands.
- Histopathological findings confirmed idiopathic plantar hidradenitis.
- The case highlights the importance of biopsy in diagnosing plantar hidradenitis.
Implications:
- This case expands the understanding of idiopathic plantar hidradenitis in pediatric patients.
- Accurate diagnosis is essential for appropriate management and to differentiate from other plantar conditions.
- Further research into vaccine-associated plantar hidradenitis may be warranted.
