This report details a rare case of multiple trichoepitheliomas, a benign skin tumor, co-occurring with epidermal cysts. The extensive lesions presented uniquely, mimicking other skin conditions.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Trichoepitheliomas are benign adnexal neoplasms originating from follicular structures.
  • Multiple trichoepitheliomas can be associated with genetic syndromes, though this case appears sporadic.
  • Epidermal cysts are common benign skin cysts, but their association with extensive trichoepitheliomas is less frequent.

Observation:

  • A patient presented with florid and widespread trichoepithelioma lesions.
  • Large nodulo-cystic trichoepitheliomas were observed on the facial region.
  • A novel presentation of trichoepithelioma, resembling hidradenitis suppurativa, was noted near the gluteal cleft.

Findings:

  • The case highlights the diverse clinical manifestations of trichoepitheliomas.

Related Experiment Videos

  • The association of multiple trichoepitheliomas with epidermal cysts was confirmed.
  • A simulated hidradenitis suppurativa variant of trichoepithelioma represents a new clinical observation.

    • Implications:

    • This case expands the differential diagnosis for facial nodulo-cystic lesions.
    • Understanding atypical presentations of trichoepithelioma is crucial for accurate diagnosis and management.
    • Further research may elucidate the pathogenesis of this extensive trichoepithelioma variant.
