#2: 2007 MP/H Rules
Question:
MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply to the classification of succinate dehydrogenase-deficient renal cell carcinoma? See Discussion.
Discussion:
Partial nephrectomy showed carcinoma, histologic type: succinate dehydrogenase-deficient renal cell carcinoma. This is not a term in the ICD-O, and is not a histology covered in the Kidney MPH rules. However, a recent web search indicates this is a specific type of RCC that was added to the 2016 WHO classification of RCC (per abstract: https://www.ncbi.nlm.nih.gov/pubmed/27179267) and makes up 0.05-0.2% of RCC cases (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4229399/).
Answer:
Code the histology to renal cell carcinoma, NOS (8312/3). While WHO lists succinate dehydrogenase-deficient renal cell carcinoma in the latest edition, no specific histology code is provided. MP/H Rule H10 applies since only one histology type is provided, though no code is listed.
