Sebaceous lymphadenoma is a rare, benign tumor that originates from the sebaceous gland. It is also known as a lymphadenoma sebaceum. This tumor is typically found in the salivary gland, particularly the parotid gland.

Symptoms

The primary symptom of a sebaceous lymphadenoma is a slow-growing, painless mass. This mass is typically located in the parotid gland, but can also occur in other salivary glands. The mass is usually less than 3 cm in diameter.

Diagnosis

The diagnosis of sebaceous lymphadenoma is typically made through a combination of physical examination, imaging studies, and biopsy. Imaging studies such as ultrasound, computed tomography (CT) scan, and magnetic resonance imaging (MRI) can help to determine the size and location of the tumor. A biopsy, in which a small sample of tissue is removed and examined under a microscope, is usually necessary to confirm the diagnosis.

Treatment

The treatment for sebaceous lymphadenoma is usually surgical removal of the tumor. In some cases, radiation therapy may also be used. The prognosis for individuals with sebaceous lymphadenoma is generally good, as this tumor is benign and does not typically spread to other parts of the body.
