[An exceptional mimicker of ovarian tumors: cancer in a pelvic horseshoe kidney].

Abstract

BACKGROUND:

although the horseshoe kidney is a frequent congenital abnormality, the likelihood of it 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, firm, and fixed. On pelvic examination the mass was easily palpated through the vaginal fornix. 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 confirmed. 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.
