Abstract
Masses are commonly detected in the kidneys either as incidental findings or upon workup of urinary symptoms on an initial presentation. We describe a large series of rare cases in which individuals presented with symptoms or imaging findings of kidney masses concerning for primary carcinoma of renal cell or urothelial origin but were found on pathological analysis to be lymphomas or atypical lymphoid proliferations, with or without an accompanying renal malignancy. These mass lesions, including some unique mimics of renal carcinomas such as reactive follicular hyperplasia and IgG4-related disease primary to the kidney, are all lymphoid kidney proliferations from a single institution. Herein, we demonstrate the need for consideration of lymphoid abnormalities in the diagnosis of renal masses, which can affect further workup and management. We also review the differential diagnosis of primary renal masses originating from neoplastic and non-neoplastic lymphoid disorders.
期刊介绍:
Manuscripts of original studies reinforcing the evidence base of modern diagnostic pathology, using immunocytochemical, molecular and ultrastructural techniques, will be welcomed. In addition, papers on critical evaluation of diagnostic criteria but also broadsheets and guidelines with a solid evidence base will be considered. Consideration will also be given to reports of work in other fields relevant to the understanding of human pathology as well as manuscripts on the application of new methods and techniques in pathology. Submission of purely experimental articles is discouraged but manuscripts on experimental work applicable to diagnostic pathology are welcomed. Biomarker studies are welcomed but need to abide by strict rules (e.g. REMARK) of adequate sample size and relevant marker choice. Single marker studies on limited patient series without validated application will as a rule not be considered. Case reports will only be considered when they provide substantial new information with an impact on understanding disease or diagnostic practice.
