Area of Science:

  • Dermatology
  • Pediatric Dermatology
  • Histopathology

Background:

  • Localized hyperhidrosis presents a diagnostic challenge, particularly in pediatric cases.
  • Understanding the etiology of focal sweating is crucial for appropriate management.

Observation:

  • A 7-year-old girl presented with localized hyperhidrosis affecting her left forearm.
  • Clinical examination revealed excessive sweating confined to a specific area.

Findings:

  • Histopathological examination of a biopsy specimen confirmed the presence of an eccrine nevus.
  • The eccrine nevus is identified as the likely cause of the localized hyperhidrosis.

Implications:

  • This case expands the differential diagnosis for focal sweating disorders in children.
  • Eccrine nevi should be considered in the evaluation of pediatric localized hyperhidrosis.
  • Further research into the relationship between eccrine nevi and hyperhidrosis is warranted.
