Medical Care

The treatment of the trichoepithelioma lesion is primarily surgical. A Brazilian study of several types of cutaneous tumors reported only a partial response for trichoepithelioma to 5% imiquimod cream.[25]

Surgical Care

Solitary lesions can be excised. In the case of multiple tumors, this surgical approach may not be feasible.

Split-thickness skin grafting, dermabrasion, and laser surgery have been proposed, but the results of these procedures vary.[26, 27]

Management of either form (ie, solitary, multiple/hereditary) by superficial biopsy is usually adequate.

Recurrence of solitary trichoepithelioma is uncommon. When the multiple facial lesions are surgically flattened by dermabrasion or laser therapy, they tend to regrow into elevated papules or nodules. This regrowth may occur rapidly within months, or it may take several years. Some patients find a prolonged cosmetic improvement to be worthwhile even if repeated procedures are necessary.

Characteristic clinical morphologic features. Notice the numerous, small papules, predominantly close to the midline.
Image of glass slide showing a nodular, very well-circumscribed proliferation.
Well-circumscribed, superficial lesion composed of clusters of basaloid cells within a fibrous stroma. This arrangement of epithelial cells and stroma is described as organoid.
The cystic spaces contain keratin. Notice the lack of mitotic figures or apoptotic bodies.
Papillary-mesenchymal bodies are structures associated with hair follicle differentiation. They are characterized by an aggregate of spindle, stromal cells, closely apposed to a hair bulb (arrow; darkly staining, basaloid epithelial cells).
Because trichoepitheliomas recapitulate follicular differentiation, they may contain cells commonly seen in hair follicles such as melanocytes. This image illustrates both melanocytes (black arrow) and dermal melanophages (white arrow).
Immunohistochemical studies detect expression of CD34 by many of the dendritic cells that surround the tumor aggregates (anti-CD34, diaminobenzidine, and hematoxylin).
Desmoplastic variant. Notice that many of the aggregates of basaloid cells are small, resembling a syringoma; however, they contain keratin instead of eccrine secretion. Also notice the characteristic markedly fibrous stroma.
High-powered view of desmoplastic trichoepithelioma. Notice the cluster of squamous cells surrounding a small cystic area containing keratin. Intervening stroma is markedly fibrous.
The malignant counterpart, trichilemmal carcinoma, typically shows areas with infiltrative growth and necrosis.
Trichilemmal carcinoma cells have large, lightly stained cytoplasm with large, pleomorphic nuclei. As a sign of follicular differentiation, some cells may display the characteristic cytoplasmic, red, trichohyalin granules (arrows).
