    Area of Science:

    • Dermatopathology
    • Surgical Pathology

    Background:

    • Trichoadenoma is a rare benign skin appendage tumor.
    • Distinguishing trichoadenoma from other adnexal tumors is crucial for accurate diagnosis.

    Observation:

    • A 50-year-old male presented with a year-long asymptomatic nodule on the left pre-auricular region.
    • Clinical diagnosis suggested an epidermoid cyst.

    Findings:

    • Histological examination revealed an intradermal lesion with keratinous cysts and solid epithelial nests.
    • The lesion lacked features of basaloid tumors or hair follicle differentiation, supporting trichoadenoma diagnosis.
    • Absence of inflammation and clear separation from the epidermis were noted.

    Implications:

  • This case highlights the importance of histological evaluation for rare skin tumors.
  • Understanding trichoadenoma's distinct features aids in differential diagnosis and patient management.
  • Further research into trichoadenoma's nosological autonomy is warranted.
