What Is a Sebaceous Adenoma?
This disease, also called sebaceous gland epithelioma, is an independent disease. Some people think that it is a variant of sebaceous adenoma, or a state between sebaceous adenoma and basal cell carcinoma. Some people think it is the base of differentiation to sebaceous glands Synonym for cell carcinoma. It is more common in women and appears as isolated pimples, nodules, tumors on the scalp or face, yellow to orange.

Clinical manifestations of sebaceous adenoma
- This disease is rare. Occurred in women over 60 years old, also occurred shortly after birth.
- Tumors are more common on the face and scalp. They are a papule, nodule, or tumor with a diameter of 1 to 3 mm, yellow to orange, or flesh, and occasionally several. Sebaceous adenomas can also occur in skin lesions of seborrheic keratosis or sebaceous nevus, and may also be a manifestation of Torre-Muir syndrome (Miao-Thor syndrome). No local recurrence or metastasis has been reported.
Sebaceous adenoma diagnosis
- Clinically, isolated pimples, nodules, or tumors on the face or scalp, yellow to orange or flesh-colored, and some of them occur on skin lesions of seborrheic keratosis or sebaceous nevus. Histopathology is an unclear, irregularly growing cell mass that is solid or glandular, can be connected to the epidermis, has no envelope, and is similar to basal cell carcinoma, but a part of its cells clearly differentiates into sebaceous glands, most of which are not Differentiated cells. These cell masses are arranged in a fence-like pattern around the germinal cells (ie, basal cells) similar to the sebaceous glands, which are not easily distinguished from basal cell tumors.
Differential diagnosis of sebaceous adenoma
- This disease needs to be distinguished from sebaceous adenomas, basal cell carcinomas that differentiate into sebaceous glands, highly differentiated sebaceous adenocarcinomas, and hairy cell tumors that differentiate into sebaceous glands.
