Desmoplastic trichoepithelioma is a rare benign skin tumor. This case highlights its characteristic clinical and histopathological features in a young adult male.

Area of Science:

  • Dermatopathology
  • Oncology

Background:

  • Desmoplastic trichoepithelioma (DT) is a rare benign adnexal neoplasm.
  • DT typically presents as a solitary facial papule or nodule.

Observation:

  • A 20-year-old male presented with a 4-year history of a solitary, 8 mm nodule on the left temple.
  • The lesion exhibited normal overlying skin, a central depression, and elevated borders.

Findings:

  • Histopathology revealed nests and strands of basaloid cells within a dense fibrous stroma.
  • Numerous horn cysts were observed amidst the neoplastic cells, consistent with DT.

Implications:

  • Accurate clinical and histopathological diagnosis is crucial for differentiating DT from other skin neoplasms.
