A rare, aggressive sebaceous carcinoma of the cheek, unrelated to prior radiation, was diagnosed in an elderly man. This case highlights the aggressive nature and discusses treatment strategies for these uncommon skin cancers.

Area of Science:

  • Dermatopathology
  • Oncology
  • Head and Neck Surgery

Background:

  • Sebaceous carcinoma is a rare malignant neoplasm arising from sebaceous glands.
  • Extraocular sebaceous carcinomas are uncommon, particularly in patients without a history of radiation therapy.
  • These tumors can exhibit aggressive behavior and pose diagnostic challenges.

Observation:

  • A 79-year-old male presented with a large, ulcerated cheek tumor.
  • Histological examination revealed features consistent with sebaceous carcinoma, lacking squamous or basal differentiation.
  • Immunohistochemical analysis showed positive Sudan staining, expression of suprabasal keratins, and negativity for carcinoembryonic antigen, vimentin, and S100 protein.

Findings:

  • The tumor was identified as a true sebaceous carcinoma.

  • The absence of prior irradiation and the aggressive clinical presentation were notable.
  • Specific immunohistochemical markers supported the diagnosis of sebaceous carcinoma.

    • Implications:

    • This case underscores the importance of considering sebaceous carcinoma in the differential diagnosis of ulcerated facial tumors, even without a history of radiation.
    • The aggressive nature of these tumors necessitates prompt diagnosis and appropriate management.
    • Further discussion on optimal treatment regimens for extraocular sebaceous carcinoma is warranted.
