Аннотация
INTRODUCTION: Mixed tumor in the same lymph nodes is extremely rare and no previous reports have described mixed tumor comprising urothelial carcinoma and malignant lymphoma.
CASE PRESENTATION: A 71-year-old woman visited a local clinic with a main complaint of hematuria. Imaging revealed right hydronephrosis and a mid-ureter tumor shadow. Positron emission tomography-computed tomography showed high uptake of fluorodeoxyglucose in para-aortic lymph nodes. Abdominal para-aortic lymph node biopsy was performed. Pathology showed urothelial carcinoma and malignant lymphoma in the same lymph nodes, where a mixed tumor was diagnosed.
CONCLUSION: We encountered a case of mixed tumor of urothelial carcinoma and Hodgkin lymphoma, which metastasized to the same tissues.
