Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Seborrheic keratosis is a common benign skin tumor.
  • Traumatic lesions can sometimes mimic other dermatological conditions.

Observation:

  • A 72-year-old female presented with a 1-year history of a 2 x 1.5 cm purple verrucous lesion.
  • The patient reported a history of repetitive trauma to the affected area.

Findings:

  • Clinical diagnosis suggested traumatic seborrheic keratosis.
  • Histological examination confirmed the lesion as a clear cell acanthoma.

Implications:

  • This case highlights the importance of histological examination for accurate diagnosis.
  • Clear cell acanthoma should be considered in the differential diagnosis of verrucous lesions, especially after trauma.
