Pigmented squamous cell carcinoma rarely occurs on the skin. This rare forehead cancer can mimic melanoma or basal cell carcinoma, necessitating careful diagnosis.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Pigmented squamous cell carcinoma (PSCC) is uncommon on the skin, with most cases reported in oral and ocular mucosae.
  • Distinguishing PSCC from other pigmented skin lesions is clinically challenging.

Observation:

  • A case of PSCC on the forehead is presented.
  • The lesion's pigmented nature can lead to diagnostic confusion.

Findings:

  • PSCC can be mistaken for pigmented basal cell carcinoma.
  • It may also be confused with melanoma, particularly those with pseudoepitheliomatous hyperplasia.

Implications:

  • PSCC should be considered in the differential diagnosis of atypical pigmented skin lesions.
