RESUMEN
An increased number of patients with syphilis was recently reported in Japan and the United States. Syphilitic orchitis, a late complication of syphilis, is a rare disease that presents as testicular swelling. In most cases, a diagnostic orchiectomy is performed because of the possibility of testicular cancer. We report a case treated conservatively with antibiotics considering the possibility of syphilitic orchitis based on the blood test results and describe long-term changes observed in the imaging findings.
RESUMEN
Introduction: Small-cell carcinoma of the urinary bladder has a poor prognosis, and no standard treatment has been established. We encountered a case of a patient with metastasis in which complete response and long-term survival were obtained by treating the primary lesion with a combination of irinotecan, carboplatin chemotherapy, and radiation therapy. Case presentation: An 83-year-old man was diagnosed with a bladder tumor with liver metastasis. Small-cell carcinoma was diagnosed via transurethral resection. Second-line chemotherapy with irinotecan and carboplatin and irradiation of the primary lesion were significantly effective. The imaging evaluation showed a complete response. The therapeutic effect was maintained for 1 year, even after the discontinuation of chemotherapy. Conclusion: Irinotecan and carboplatin should be considered for the treatment of small-cell carcinoma of the bladder. Irradiation of the primary lesion may also be useful if the extent of metastasis is low.
