A rare vulvar keratoacanthoma, a benign skin tumor, was successfully treated with wide local excision. This case highlights the importance of correlating clinical findings with histology for accurate diagnosis, especially given its similarity to squamous cell carcinoma.

Area of Science:

  • Dermatology
  • Oncology

Background:

  • Keratoacanthomas are benign skin tumors originating from follicular epithelium.
  • Vulvar involvement is exceptionally rare, with only one prior reported case.
  • Distinguishing keratoacanthomas from squamous cell carcinoma is crucial due to clinical and histological similarities.

Observation:

  • A 54-year-old woman presented with a 1 cm, nonulcerated vulvar lesion on the labium majus.
  • The lesion had been present for approximately one month without induration or hyperkeratosis.
  • The patient underwent wide local excision for the vulvar lesion.

Findings:

  • The clinical-pathologic diagnosis confirmed the lesion as a keratoacanthoma.
  • Post-excision, the patient remained disease-free for a two-year follow-up period.

  • This case adds to the limited literature on vulvar keratoacanthomas.

    • Implications:

    • Accurate diagnosis of vulvar keratoacanthoma requires correlating clinical presentation with histological findings.
    • Dermatopathology consultation is recommended for challenging cases.
    • Prompt surgical management can lead to favorable outcomes for vulvar keratoacanthomas.
