A 62-year old man presented with a 12-month history of a skin lesion on his forehead. It had stopped growing three months ago. The lesion was asymptomatic. There was no other relevant history.
The lesion was a skin-coloured 5 mm papule with a tuft of hair growing from the centre.
What is the diagnosis?
The diagnosis is a trichofolliculoma
This is a rare appendageal tumour, best regarded as a hamartoma of the pilosebaceous follicle, which results in several hairs being formed within the follicular opening and all protruding onto the epidermal surface from a pilosebaceous orifice.
Trichofolliculoma shows a predilection for the head and neck, particularly the face. Occasionally, tumours present in the vulva or other unusual sites including the upper extremities, external ear, penis and scrotum. Clinically, lesions can be recognised as small raised nodules with two or three hairs protruding together in a small tuft.
Lesions are benign.
