What causes Trichoblastoma?

Trichoblastoma is a rare benign tumor that arises from the germ cells of the hair follicle. The characteristic clinical presentation is a solitary, asymptomatic nodule on the face or scalp. Trichoblastoma may occur sporadically, in association with a hereditary disease, or within a nevus sebaceus.

What is a Trichoepithelioma?

Trichoepithelioma is a rare benign skin lesion that originates from hair follicles. Trichoepitheliomas are mostly seen in the scalp, nose, forehead, and upper lip. These skin lesions originate from benign proliferation of epithelial-mesenchymal origin cells.

How do you get rid of Trichoblastoma?

Occasionally true trichoblastomas may be excised for cosmetic reasons or if they occur in functionally sensitive areas. Treatment options include curettage and electrodesiccation or surgical excision.

Where does trichoadenoma occur in the human body?

How big are the nodules in a trichoadenoma?

They are usually solitary nodules ranging from 0.5 to 1.5cm in size. On histology, trichoadenomas consist of multiple keratin-filled horn cysts, lined with stratified squamous epithelium intermingled with solid islands or strands of basaloid or infundibular cells lying within a sclerotic stroma in the dermis.

Is it necessary to remove a trichoadenoma tumor?

The treatment of Trichoadenoma may involve the following: In a majority of cases, removal of the tumor is not necessary, unless it causes bothersome signs and symptoms such as cosmetic issues.

Can a trichoadenoma be mistaken for basal cell carcinoma?

Trichoadenomas can present on the eyelids and can be mistaken for basal cell carcinoma. Rarely, trichoadenomas are combined with intradermal melanocytic nevi, and can be seen together with pigmented lesions, as was seen in one case. Only one case of trichoadenoma arising from a nevus sebaceous has been reported.
