Concurrent bilateral testicular hamartomas and serous borderline tumors in a patient with complete androgen insensitivity syndrome: a case report and review of the literature

We report a case of complete androgen insensitivity syndrome (CAIS) accompanied by serous borderline tumors in a 75-year-old patient. Müllerian epithelial tumors are extremely rare condition in CAIS patients with only a few case reports. We report a case of late-diagnosed testicular feminization with hamartomas, and the first report of serous tumor with borderline malignant potential in such cases.
