Abstract

Simultaneous occurrence of non-Hodgkin’s lymphoma (NHL) and solid carcinomas, such as colon, lung, and breast cancers, is relatively rare. We report a case of coincidental detection of diffuse large B-cell lymphoma (DLBCL) in the inner inguinal lymph node of a patient with uterine endometrial cancer FIGO stage IA. The patient was a 69-year-old woman and she visited a primary care doctor presenting with increased vaginal discharge. She was diagnosed as having uterine endometrial carcinoma. Laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection were performed. The final pathologic examination revealed uterine endometrial carcinoma (endometrioid carcinoma grade 1) and DLBCL was detected in the inner inguinal lymph node. No other malignant lymphoma legions were detected by positron emission tomography-computed tomography (PET-CT). She was diagnosed as having uterine endometrial carcinoma FIGO stage IA (pT1apN0pM0) and malignant lymphoma stage I according to the Ann Arbor clinical staging system. She was treated with six cycles of chemotherapy comprising rituximab, cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) for the malignant lymphoma. The patient remains in complete remission 8 months after completing chemotherapy.
