Here, we report a case of retroperitoneal ganglioneuroma with multifocal bone involvement in a middle-aged woman. A 43-year-old female was incidentally diagnosed with a retroperitoneal tumor on abdominal ultrasonography. Contrast-enhanced computed tomography revealed a retroperitoneal tumor that was 11 cm in diameter above her left kidney and multiple bone lesions. Fluorodeoxyglucose positron emission tomography (FDG-PET) showed a slightly high FDG uptake (standardized uptake value (SUV) max, 3.7) in the retroperitoneal mass and mild accumulation in the L1 vertebral body, zygoma, acetabulum, and calcaneus. Biopsies were performed for the retroperitoneal and lumbar spine tumors, both of which were diagnosed as ganglioneuromas. Total surgical resection is the standard treatment of this condition ; however, for this patient, it was difficult to remove all the tumors, and the ganglioneuromas generally followed a benign course. Therefore, a watchful waiting approach was chosen and no tumor growth was observed three years after her first visit to our hospital.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 2","pages":"43-48"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-two years after the surgery, computed tomography (CT) showed a retroperitoneal mass 3 cm in diameter. Positron emission tomography (PET) -CT revealed high FDG uptake in both the right testis and retroperitoneal mass. Regarding serum tumor markers, α fetoprotein (AFP) was slightly elevated to 12.5 ng/ml. He underwent right radical orchiectomy, and pathological examination revealed pure seminoma. After surgery, the serum AFP level remained high (12. 9 ng/ml), and we initially considered this nonseminoma patient to have a good prognosis according to International Germ Cell Consensus Classification. During three cycles of a combination regimen including bleomycin, etoposide, and cisplatin (BEP), we performed adjustment of immunosuppressive therapy, treatment for Cytomegalovirus infection (valganciclovir hydrochloride), and that for other adverse events associated with systemic chemotherapy. The chemotherapy schedule was delayed, and bleomycin (third course, day 15) was skipped due to adverse effects. After 3 cycles of BEP, the retroperitoneal lymph node metastasis shrunk from 3.0 to 1.5 cm in diameter. In contrast to the good radiological response, the serum AFP level gradually increased during the treatment to 102.6 ng/ml. Therefore, we did not consider the AFP elevation to have derived from residual cancer, and decided to perform close follow-up. During the 3-year follow-up, AFP decreased to around 20 ng/ml, and PET-CT did not show any uptake in the retroperitoneal mass or other sites.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 1","pages":"9-15"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143123825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some patients require withdrawal or dose reduction due to cutaneous symptoms associated with EV treatment. Currently, the only reported associations of EV with cutaneous symptoms are pre-treatment performance status (PS) and body weight. However, no report has focused on the association between hematological factors and cutaneous symptoms. We retrospectively examined the occurrence of cutaneous symptoms and associated factors in patients who had been treated with EV for UC at Nagasaki University Hospital between February 2022 and June 2023. We evaluated the six patients with bladder cancer and three cases of upper urinary tract cancer. The median age was 73 [57-85] years. Seven patients had cutaneous reactions with EV treatment, and the median date of onset of the cutaneous symptoms was seven　[4 -28] days. PS was better inthe group with skinsymptoms compared with the group without (median : 1.0 vs 3.0), and in those with a higher incidence of eosinophilia or cutaneous symptoms on the previous regimen (71. 4% vs 0%). We suggested that the presence of eosinophilia or cutaneous symptoms at the time of pre-EV regimen administration may be a predictor of the appearance of cutaneous symptoms at the time of EV treatment. The limitation is that it is a single-center, small-case series, which does not allow for a rigorous statistical study.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"70 11","pages":"361-366"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142878228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography (CT) revealed right testicular swelling, multiple lung metastases, and small intestinal wall thickening. The patient's β-human chorionic gonadotropin, alpha-fetoprotein, lactate dehydrogenase, and hemoglobin levels were 103.3 ng/ml, 20.8 ng/ml, 300 U/l, and 11.3 g/dl, respectively. He underwent high orchidectomy after being diagnosed with a testicular tumor and multiple lung metastases. Histopathological examination revealed a mixed germ cell tumor (60% choriocarcinoma, 20% seminoma, 10% embryonal carcinoma, 10% mature teratoma, and 1% yolk sac tumor). As the patient exhibited active gastrointestinal hemorrhage requiring frequent blood transfusions, gastrointestinal endoscopy was performed to investigate its cause. When upper and lower gastrointestinal endoscopies revealed no bleeding, the patient was referred to our hospital for further examination and treatment. A small bowel endoscopy revealed a hemorrhagic jejunal mass. Because endoscopic hemostasis was challenging, we partially resected the small intestine. Pathological findings in the resected lesion were consistent with small intestinal metastasis of the testicular tumor. The tumor markers turned negative after four cycles of BEP and four cycles of TIP chemotherapy. He then underwent resection of the remaining lung tumor, and no residual tumor or recurrence was detected one year later.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"70 11","pages":"379-386"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142878295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
