Initial presentation of renal cell carcinoma as a vaginal mass with excessive bleeding.

Introduction: Renal cancer is the seventh most common cancer in men and the tenth most common cancer in women. Renal cell carcinoma accounts for 3% of all adult malignancies and 85% of all primary renal tumours. It metastasizes most often to the lungs, liver, bones, and brain and very rarely to the vagina.

Case report: We present a case of a 60-year-old patient, in whom the renal cell carcinoma manifested for the first time as an intense bleeding, soft tumour formation with dimensions 4/6 cm originating in the vagina.

Discussion: Renal cell carcinoma metastasizes in about 30% of cases. Metastasizing can be lymphatic, hematogenous, transcoelomic, or by direct invasion. Most commonly it affects the lungs, bones, adrenal glands, liver, lymph nodes, and brain. Much less often, it metastasizes to the thyroid, orbit, nasal structures, vagina, gallbladder, pancreas, sublingual tissues, and soft tissues of distal extremities. Metastases can be synchronous and metachronous. The described cases in the literature of renal cell carcinoma manifested with vaginal metastases are isolated.

Conclusions: We present an extremely rare case of renal cell carcinoma manifested by profuse genital bleeding from a vaginal metastasis. In such cases, especially if the vaginal lesion does not appear as the primary vaginal carcinoma, we must consider the possibility of metastasis from renal carcinoma.
