Trichofolliculoma is a rare hair follicle hamartoma, which is often regarded as a hair follicle tumor. Mostly, it presents as a papule or nodule, involving the skin of the face and scalp area. A central, dilated keratin plugged ostium with vellus hair(s) is often present. We report a 19-year-old woman with typical clinical and histopathological findings of trichofolliculoma.
Folliculosebaceous cystic hamartoma (FSCH) is a rare cutaneous hamartoma characterized by follicular, sebaceous, and mesenchymal elements. Folliculosebaceous cystic hamartoma is probably not as rare as previously thought and its inclusion in the differential diagnosis of asymptomatic skin colored papules or nodules is warranted, especially if it is present in the head and neck region.
