Status Final References Source 1: 2007 SEER Manual pgs: C-1066 Notes: Appendix C Source 2: WHO Class of Female Gen Organ pgs: 319 Notes: 2003 Question MP/H Rules/Histology: Final diagnosis from a partial vulvectomy says, "vulvar intraepithelial neoplasia III, basaloid type." Is this VIN III (8077/2) or basaloid squamous cell carcinoma (8083 and change the bevavior code from 3 to 2)? Which Histology rule applies? It seems to me that H4 and H6 both lead to 8083. Discussion Answer Assign 8077/2 [Squamous intraepithelial neoplasia, grade III] for VIN III diagnoses, regardless of the type. According to the WHO Classification of Tumours(page 319), "VIN is predominately of the warty or basaloid types..." Use the multiple tumors module to determine the histology code for VIN. Rule H21 applies. History Last Updated 10/14/09 | |
