Trichofolliculoma

Trichofolliculoma is a rare, benign tumor that originates from the hair follicle. It is characterized by a central, dilated hair follicle surrounded by smaller, radiating follicles. Trichofolliculoma is typically found on the face, particularly the nose, and is more common in adults than in children.

Signs and Symptoms

Trichofolliculoma presents as a small, solitary, skin-colored or pink papule with a central hair. The lesion is usually less than 1 cm in diameter and is often mistaken for a mole or skin tag.

Causes

The exact cause of trichofolliculoma is unknown. However, it is believed to be related to hair follicle stem cells.

Diagnosis

The diagnosis of trichofolliculoma is made by biopsy of the lesion. Under the microscope, the characteristic finding is a large, central hair follicle surrounded by smaller, radiating follicles.

Treatment

Treatment of trichofolliculoma is usually not necessary, as the lesion is benign and does not cause symptoms. However, if the lesion is bothersome or cosmetically unacceptable, it can be removed by surgical excision.
