Trichofolliculoma is an uncommon small benign tumour originating from the hair follicle tissue. It typically presents as a small, solitary flesh-coloured or whitish nodule that occurs most often on the face around the nose region. Sometimes the lesion(s) have a central pore or black dot from which exudes sebaceous-like fluid (sebum), and is known as pore of Winer. In some cases a tuft of white hair may be growing from the central pore.
Apart from its physical appearance, trichofolliculoma shows no other signs or symptoms.
Trichofolliculoma is sometimes called folliculoma.
A small biopsy (when a tiny piece of skin is removed under local anaesthetic) is the only definitive diagnosis for trichofolliculoma. The histology of trichofolliculoma will differentiate it from other benign follicular tumours that have similar clinical presentations, these include dilated pore of Winer, pilar sheath acanthoma, and trichoepithelioma.
Trichofolliculoma is a benign follicular tumour that requires no treatment. Occasionally they may be excised for cosmetic reasons or if they occur in functionally sensitive areas. Treatment options include curettage and electrodesiccation or surgical excision.
