Is Trichoblastoma malignant?
While basal cell carcinoma rarely metastasizes, it is locally invasive [9]. In contrast, trichoblastoma rarely undergoes a malignant transformation into trichoblastic carcinoma, which is a locally invasive and metastatic tumor [1].
What is Trichilemmal carcinoma?
Trichilemmal carcinoma (TC) is a rare malignant tumor that develops from the external root sheath of the hair follicle. It usually is found in the skin that occurs on the sun-exposed areas of the body [1].
How do you get rid of Trichoblastoma?
Complete excision is the best surgical option for patients with trichoblastomas for several reasons. Trichoblastoma is commonly a solitary lesion and basal cell carcinoma is an important differential diagnosis that needs to be ruled out. In addition, all adnexal tumors can extend deep into the dermis.
How do you get rid of trichoepithelioma?
All in all, as a benign tumor, trichoepithelioma can be managed safely with surgical removal. Alternatives include dermal abrasion and laser surgery, curettage although these options may be associated with an increased rate of recurrence.
Is sebaceous adenoma malignant?
A sebaceous adenoma is a small bump on a gland in your skin (sebaceous gland). It’s a harmless, benign tumor in a hair follicle.
What causes trichoblastic carcinoma to develop?
The tumour arises from follicular germinative cells and develops dermal or subcutaneous fat invasion. In the very few reported cases of trichoblastic carcinoma, the primary trichoblastoma lesion had been a painless mass slowly growing over a period of years.
Can a trichoblastoma grow on the eyelid?
The eyelid is an unusual location for a trichoblastoma, but this location has been reported in the literature. It is important to keep in mind that, rarely, long-standing trichoblastomas can transform into malignant trichoblastic carcinoma.
What is the incidence of trichoblastomas?
While the exact incidence is unknown, trichoblastomas are rare benign tumors. They may occur at any age and do not have specific predilection to either females or males. There is no race predominance reported. Patients with nevus sebaceous are at risk of developing trichoblastomas.
What is the best surgical treatment for trichoblastoma?
Complete excision is the best surgical option for patients with trichoblastomas for several reasons. Trichoblastoma is commonly a solitary lesion and basal cell carcinoma is an important differential diagnosis that needs to be ruled out.
