Trichoblastoma is a small benign hair follicle tumour originating from follicular germinative cells. It is thought to be a variant of trichoepithelioma. It typically presents as a solitary mass of small skin-coloured to brown or blue-black papules or nodules, usually 1-2 cm in diameter.

2023年3月4日 · Trichoblastomas and trichoepitheliomas are benign hair-germ tumors that most commonly arise on the face and scalp of adults. They may mimic basal cell carcinoma, among other cutaneous adnexal tumors, clinically and warrant histopathologic evaluation.

Trichoblastomas are a skin condition characterized by benign neoplasms of the follicular germinative cells known as trichoblasts. [1]: 673. Trichoblastic fibroma is a term used to describe small nodular trichoblastomas that contain a conspicuous fibrocytic component, sometimes constituting over 50% of the lesion. [2]

2023年1月24日 · Trichoblastoma: Well circumscribed, predominantly dermal tumor nodule which may extend to subcutis Predominantly basaloid epithelial cells in nests with peripheral palisading

2019年3月13日 · Trichoblastomas are typically found on the face and scalp and range in size from 5mm to 8cm. They are generally nonulcerated skin-colored to brown papules or nodules. Very rarely, pigmented trichoblastomas have been reported.

Trichoblastoma is a rare, slow-growing, benign cutaneous tumor derived from follicular germinative cells. Trichoblastoma commonly appears as an asymptomatic, symmetrical, well-circumscribed, skin-colored to brown or blue-black papule or nodule.

Trichoblastomas are typically benign skin neoplasms that arise from follicular germinative cells. They manifest primarily on the scalp, face, and neck, regions abundantly populated with hair follicles. The tumour's benign nature signifies a favourable prognosis, yet its resemblance to malignant basal cell carcinoma poses diagnostic challenges.

Trichoblastoma, also known as trichoepithelioma, is an uncommon skin tumour. Trichoepithelioma is considered a superficial version of trichoblastoma; the World Health Organization lumps the two entities together.

Trichoblastoma (TB) is a rare biphasic benign adnexal neoplasm originating from follicular germ cells but clinically, it can simulate basal cell carcinoma (BCC), making the diagnosis more difficult. There are several variants of Trichoblastoma and a ...

Trichoblastoma is a rare, benign skin tumor of rudimentary hair follicles that typically appears as a solitary, skin-colored papule on the scalp or face. It may develop in isolation or arise within a sebaceous nevus. When multiple, it may be associated with Brooke-Spiegler syndrome.
