Trichoepithelioma

Trichoepitheliomas are hamartomas with pilosebaceous differentiation.
Clinically, these small, skin-colored papules can resemble milia, syringomas, or other benign skin tumors, in addition to nodular basal cell carcinomas. Diagnosis is made by histology.

Treatment:

• Surgical excision is the treatment of choice for solitary lesions.
• Histologic review is imperative to rule out basal cell carcinoma.
