Trabecular carcinoma

Trabecular Carcinoma is a rare type of skin cancer that primarily affects the sebaceous glands. It is also known as Sebaceous Carcinoma and is characterized by the abnormal growth of cells in the sebaceous glands, which are responsible for producing sebum, an oily substance that helps to keep the skin and hair moisturized.

Etiology

The exact cause of trabecular carcinoma is unknown. However, it is believed to be associated with a history of radiation therapy, immunosuppression, and Muir-Torre syndrome, a rare genetic disorder characterized by the presence of sebaceous gland tumors and internal malignancies.

Clinical Presentation

Trabecular carcinoma typically presents as a hard, painless nodule on the skin, often on the eyelid. The tumor may be yellowish in color and may bleed or ulcerate. In some cases, the tumor may cause loss of eyelashes or distortion of the normal eyelid margin.

Diagnosis

Diagnosis of trabecular carcinoma is typically made through a biopsy of the affected tissue. The biopsy sample is examined under a microscope to look for the presence of cancer cells. Immunohistochemistry may also be used to confirm the diagnosis.

Treatment

Treatment for trabecular carcinoma typically involves surgical removal of the tumor. In some cases, radiation therapy or chemotherapy may also be used. The prognosis for individuals with trabecular carcinoma is generally good, especially if the cancer is detected and treated early.
