Solitary trichoepithelioma
Solitary Trichoepithelioma (pronunciation: so-lit-er-ee tri-ko-ep-i-thee-lee-o-ma) is a rare, benign skin tumor that originates from the hair follicle.
Etymology
The term "Trichoepithelioma" is derived from the Greek words "trichos" meaning hair, "epithelion" meaning epithelium, and "oma" meaning tumor.
Definition
A Solitary Trichoepithelioma is a noncancerous tumor that typically appears as a small, solitary, skin-colored papule on the face. It is derived from the outer root sheath of the hair follicle.
Symptoms
The primary symptom of a solitary trichoepithelioma is the presence of a small, firm, skin-colored or pink papule. The papule is typically less than 1 cm in diameter and is most commonly found on the face, particularly the nose and cheeks.
Diagnosis
Diagnosis of solitary trichoepithelioma is typically made through a biopsy of the lesion. Histologically, it is characterized by nests of basaloid cells, horn cysts, and a stroma resembling the fibrous root sheath of a hair follicle.
Treatment
Treatment options for solitary trichoepithelioma include surgical excision, laser therapy, and cryotherapy. However, as the condition is benign, treatment is often not necessary unless the lesion is causing discomfort or cosmetic concern.
