ABSTRACT
Conventional renal cell carcinomas have a straightforward diagnosis. However a different subset of renal neoplasms with prominent tubulopapillary histomorphology pose a diagnostic challenge due to significant overlap of microscopic features and very few points of differentiation between them. These constitute collecting duct carcinoma, renal medullary carcinoma, adenocarcinoma of renal pelvis; translocation associated renal carcinoma and mucinous tubular & spindle cell carcinoma. Hereby short case reports of three of these entities are presented with a comprehensive review of literature related to diagnostic and therapeutic inputs on renal neoplasms with tubulopapillary architecture.
Key words: Tubulopapillary, Carcinoma, Renal, Diagnosis
