Crohn's disease and multilocular cystic renal neoplasm of low malignant potential: An unusual association
نویسندگان
چکیده
Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract. Patients with this disease have an increased risk for both intestinal and various extra-intestinal malignancies. This risk is mainly attributed to chronic inflammation and druginduced immunosuppression. Various extra-intestinal malignancies, such as lymphoproliferative disorders and non-melanoma skin cancers occur more frequently in IBD patients compared to the general population, mainly in those using immunosuppression. The association between IBD and renal cell carcinoma (RCC) was reported in a cohort study including 180 patients.1 However, the association with multilocular cystic renal neoplasm (MCRN) of low malignant potential has not been described previously. We report the observation of a patient with a crohn disease and incidental MCRN of low malignant potential.

Cystic renal neoplasms and renal epithelial stromal tumors are diagnostically challenging and represent some novel tumor entities. In this article, clinical and pathologic features of established and novel entities are discussed. Predominantly cystic renal tumors include cystic nephroma/mixed epithelial and stromal tumor, synovial sarcoma, and multilocular cystic renal cell carcinoma. These ent...
متن کاملNo tumor-free waiting period after treatment of multilocular cystic renal cell carcinoma: a new case and review of the literature.
Most pretransplant malignancies require a tumor-free waiting period before transplantation. End-stage renal disease (ESRD) patients have an increased risk of renal cell carcinoma (RCC), which is mostly detected from routine screening during pre-kidney transplant evaluation. RCC must be quiescent prior to kidney transplantation. However, the tumor-free waiting period for RCC varies depending on ...
