Area of Science:

  • Dermatopathology
  • Oncology

Background:

  • Superficial epithelioma with sebaceous differentiation (SESD) is a rare, benign skin neoplasm described in 1980.
  • SESD is characterized by distinct histological features, differentiating it from other sebaceous tumors.

Observation:

  • A 38-year-old Japanese woman presented with a small, yellow, flat-topped plaque on her right upper eyelid.
  • Histological examination revealed a superficial dermal tumor with epidermal attachments, exhibiting plate-like proliferation.
  • Tumor cells showed basaloid features with sebocytes and well-differentiated sebaceous lobules, forming cystic spaces.

Findings:

  • The case presented aligns with the original description of SESD by Rothko, Farmer, and Zeligman.
  • Histological findings include multilobular structure, superficial dermal location, and specific cellular differentiation.
  • The presence of cystic spaces within sebaceous lobules is a notable feature.

Implications:

  • This report expands the geographic documentation of SESD.
  • Accurate histological diagnosis is crucial for differentiating SESD from other tumors with sebaceous differentiation.
  • Understanding SESD's characteristics aids in clinical management and prognosis.
