ABSTRACT

Background: although the horseshoe kidney is a frequent congenital abnormality, the likelihood of being the cause of a malignant tumor that looks like an ovarian neoplasm has not been reported.
Clinical case: a 53-year-old female came to the hospital with a pelvic tumor. The patient had a history of a simple hysterectomy due to uterine myomatosis. At abdominal physical examination we identified a rounded hypogastric tumor, 20 cm diameter, fi rm, and fi xed. On pelvic examination the mass was easily palpated through the vaginal fornix. With the diagnosis of a probable ovarian neoplasm, caused by a residual ovary syndrome was made, therefore she was admitted to the gynecology service. Computed tomography scans showed a tumor located in the right side of a deformed pelvic kidney. Hence, the gynecology service sent the patient to the surgical oncology department where the assumption was confi rmed. The analysis of the RX studies showed a possible neoplasm from a pelvic horseshoe kidney. The patient underwent an exploratory abdominal surgery, and a 19 cm tumor was excised. The pathology department reported a chromophobe cell carcinoma.
Conclusions: tumors in the pelvic horseshoe kidney may simulate an ovarian neoplasms in females.
