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.
