Urinary tract bleeding from a urethral caruncle mimicking genital tract bleeding

A 69-year-old Japanese woman with a post-hysterectomy status came to our primary care clinic. She presented with vaginal bleeding for the past 3 days which had developed after defecation. There was a palpable mass measuring approximately 2 cm on pelvic exam; however, heavy bleeding prevented in-depth observation. CT and MRI scans revealed that the mass was inside the urethral meatus and not in the vagina. She underwent surgical resection of the urethral tumour, and the pathological report showed no malignancy. A final diagnosis of urethral caruncle was made. Vaginal bleeding is commonly encountered in the primary care practice and is usually attributed to gynaecological diseases. However, patients and physicians may falsely regard urinary or gastrointestinal tract bleeding as one involving the genital tract. We present a case wherein vaginal bleeding was initially considered but was later identified to be due to a urethral caruncle.
