Trichoepithelioma

Trichoepithelioma is a neoplasm of the adnexa of the skin. Its appearance is similar to basal cell carcinoma.

Contents

One form has been mapped to chromosome 9p21.

Types

Trichoepitheliomas may be divided into the following types:

  • Multiple familial trichoepithelioma
  • Solitary trichoepithelioma
  • Desmoplastic trichoepithelioma

    • Pathology

    Trichoepitheliomas consisted of nests of basaloid cells. They lack the myxoid stroma and artefactual clefting seen in basal cell carcinoma. Mitoses are uncommon when compared to basal cell carcinoma.
