Question
MP/H Rules/Histology--Kidney, renal Pelvis: What histology code applies to a “tubulocystic renal cell carcinoma” ? See discussion.

Discussion
Per the resected specimen final diagnosis COMMENT in the pathology report: Tubulocystic renal cell carcinoma is a relatively new renal epithelial neoplasm that has been added to an updated WHO classification of renal tumors, The International Society of Urologic Pathology Vancouver Classification of Renal Neoplasia (Srigley et al. The International Society of Urologic Pathology Vancouver Classification of Renal Neoplasia Am J Surg Pathol. 2013;37:1469-1489). The majority of tubulocystic renal cell carcinomas reported in the literature (greater than 90%) have behaved in an indolent manner.

Answer
Code to renal cell carcinoma, NOS (8312/3) per kidney rule H3. The term "tubulocystic" is not a specific renal cell histology according to our kidney pathologist expert.
