| Definitions |
A small benign fibrovascular tumor of the dermal part of the hair disk. Trichodiscoma is rather simple in appearance and consists of a dome-shaped fibrous tumor with a prominent vascular component that fills the papillary dermis under an atrophic epidermis. As in a normal hair disk, a hair follicle may be present at one edge of the papular lesion. In contrast to trichodiscoma, fibrofolliculoma shows a keratin-plugged and often distorted hair follicle in the center of the lesion. A mantle of mucoid or fibrous stroma surrounds this central follicle; thin epithelial strands emerge from the central follicle and may form a netlike pattern. |
