Feminizing adrenocortical tumors: Literature review.
Feminizing adrenal tumors (FAT) are extremely rare tumors prevailing in males. Clinical manifestations are gynecomastia and/or other hypogonadism features in adults. They are rarer in pediatric population and their main manifestation is peripheral sexual precocity. In women genital bleeding, uterus hypertrophy, high blood pressure and/or abdomen mass may be the only manifestations. On the biological point, estrogen overproduction with or without increase in other adrenal hormones are the main abnormalities. Radiological examination usually shows the tumor, describes its limits and its eventual metastases. Adrenal and endocrine origins are confirmed by biochemical assessments and histology, but that one is unable to distinguish between benign and malignant tumors, except if metastases are already present. Immunostaining using anti-aromatase antibodies is the only tool that distinguishes FAT from other adrenocortical tumors. Abdominal surgery is the best and the first line treatment. For large tumors (≥10 cm), an open access is preferred to coeliosurgery, but for the small ones, or when the surgeon is experienced, endoscopic surgery seems to give excellent results. Surgery can be preceded by adrenolytic agents such as ortho paraprime dichloro diphenyl dichloroethane (Mitotane), ketoconazole or by aromatase inhibitors, but till now there is not any controlled study to compare the benefit of different drugs. New anti-estrogens can be used too, but their results need to be confirmed in malignant tumors resistant to classical chemotherapy and to conventional radiotherapy. Targeted therapy can be used too, as in other adrenocortical tumors, but the results need to be confirmed.
