Abstract：
Cytological examination of urine sediment is a helpful diagnostic tool for identifying renal involvement by hematological malignancies. We present the case of a 47-year-old man who was diagnosed with extranodal B-lymphoblastic lymphomas after presenting with gross hematuria as his first symptom. The presence of lymphoma cells in the urine led to a diagnosis confirmed through an immunophenotypic study using cell block sections of urine centrifuge sediment and core needle biopsy histology of the right renal pelvis mass. This case highlights the usefulness of a urine cytological study in diagnosing lymphoma involvement in the genitourinary tract. Furthermore, this paper reviews relevant literature on diagnosing lymphoma involvement from urine sediment.
摘要：
尿沉渣的细胞学检查是确定血液恶性肿瘤肾脏受累的有用诊断工具。我们介绍了一名47岁男子的病例，该男子在以肉眼血尿为首发症状后被诊断为结外B淋巴母细胞淋巴瘤。尿液中淋巴瘤细胞的存在导致通过使用尿液离心机沉淀物的细胞块切片和右肾盂肿块的核心针活检组织学进行的免疫表型研究证实了诊断。此病例强调了尿液细胞学研究在诊断泌尿生殖道淋巴瘤受累中的有用性。此外，本文综述了从尿沉渣诊断淋巴瘤受累的相关文献。
