A 33-year-old man presented with lymphoedema and obstructive nephropathy and was first diagnosed as retroperitoneal fibrosis (RF) with consistent clinical picture and radiographic findings. Further CT-guided biopsy was performed and non-Hodgkin lymphoma was diagnosed based on pathological results. RF is usually diagnosed through clinical presentation and imaging studies. However, our case proved that biopsy should be considered to exclude malignancy, even with typical presentations of RF. Follow-up after six courses of R-CHOP (rituximab, cyclophosphamide, vindesine, epirubicin and prednisone) regimen revealed complete resolution of symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
