Ultraviolet (UV) radiation can cause multiple keratoacanthomas, a rare skin condition. This case highlights an unusual adverse effect of UV therapy, even in patients with psoriasis.

Area of Science:

  • Dermatology
  • Oncology

Background:

  • Ultraviolet (UV) radiation is a known risk factor for skin cancer.
  • Keratoacanthoma is a skin neoplasm that can mimic squamous cell carcinoma but typically resolves spontaneously.
  • Multiple keratoacanthomas are rare.

Observation:

  • A patient with psoriasis developed multiple keratoacanthomas after receiving UVB phototherapy.
  • The lesions presented as hyperkeratotic papules.
  • Many of these lesions resolved spontaneously.

Findings:

  • The observed lesions exhibited the characteristic histology of keratoacanthoma.
  • UV radiation is implicated as the likely cause of these multiple lesions.

Implications:

  • Clinicians should be aware of keratoacanthoma development as a potential adverse effect of UV therapy.
  • This case underscores the oncogenic potential of UV radiation.
