Micrographs of trichoblastoma

Trichoblastoma is a rare, benign skin tumor that originates from the hair follicles. It is considered a type of follicular neoplasm and is often found on the scalp and face.

Presentation[edit]

Trichoblastomas typically present as solitary, slow-growing nodules. They are usually skin-colored or slightly pigmented and can vary in size. These tumors are most commonly diagnosed in adults, although they can occur at any age.

Histopathology[edit]

Under the microscope, trichoblastomas are characterized by nests of basaloid cells that resemble the germinal matrix of the hair follicle. The tumor cells are often arranged in a trabecular or ribbon-like pattern. The stroma surrounding the tumor nests is typically fibrous and may contain mucin.

Differential Diagnosis[edit]

Trichoblastoma must be differentiated from other basaloid tumors such as basal cell carcinoma and trichoepithelioma. Unlike basal cell carcinoma, trichoblastomas do not exhibit peripheral palisading or stromal retraction.

Treatment[edit]

The primary treatment for trichoblastoma is surgical excision. Complete removal is usually curative, and recurrence is rare. Due to their benign nature, trichoblastomas do not metastasize.

Related Conditions[edit]

Trichoblastomas are part of a spectrum of follicular tumors that include trichoepithelioma and pilomatricoma. These tumors share a common origin from the hair follicle but differ in their clinical and histological features.
