Objective: We report a case of diffuse large B-cell urethral lymphoma initial presenting with non-healing urethra ulcer.
Case report: A 68-year-old woman presented with a non-healing urethral ulcer accompanied with vulvar pruritus, which failed to medical treatment. Her medical history was unremarkable, lacking fever, weight loss or unexplained fatigue. There were no enlarged lymph nodes or palpable liver or spleen upon physical examination. Pelvic examination revealed an ulcerative lesion arising from the posterior wall of the urethral meatus. Cystourethroscopy showed no bladder involvement. Surgical excision of the urethral ulcer was done and immunohistochemical report showed a diffuse large B-cell lymphoma. Bone marrow needle biopsy and computed tomography were done and the diagnosis of primary diffuse large B-cell urethral lymphoma stage IEA was made. She underwent six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab and was free of disease for 51 months.
Conclusion: This report of urethral lymphoma was presented as a non-healing ulcer initially, which was totally different previous reports, presenting with bleeding, either vaginal or urinary, urinary frequency, dysuria, urine retention and self-perceived mass, suggesting that unhealed ulcer on the perineal area should be promptly evaluated and avoidance of unnecessary delayed therapy for possible curable disease.
