Adrenal carcinoma are a rare form of adrenal tumor compared with adrenal adenocarcinoma.

These tumors usually develop unilaterally in epithelial cells of the adrenal (as opposed to glandular cells with adenocarciomas) and frequently lead to the development of hyperadrenocorticism.

Diagnosis usually requires ultrasonographic, CT or MRI imaging to confirm. A definitive diagnosis requires laparoscopic or laparotomy assisted biopsy of the adrenal gland and histological confirmation.

Treatment is usually curative with unilateral adrenal carcinomas, although metastasis does occur in advanced cases.
