Inquiry Details
References:
WHO Class Female Genital Tumors, 424-425. 5th edition
Question:
Histology--Vulva: How is the histology coded for vulvar intraepithelial neoplasia III (VIN III)/Squamous cell carcinoma in situ from a pathology report of the vulva, 8070/2 for squamous cell carcinoma in situ or 8077/2 for VIN III? The rules do not discuss this particular situation.
Discussion:
Answer:
Assign 8077/2 for high-grade squamous intraepithelial lesion, VIN 3 in this case. The WHO Classification of Female Genital Tumors, 5th edition, states that squamous intraepithelial lesions (SILs) of the vulva are also known as vulvar intraepithelial neoplasia, HPV-associated. The term squamous cell carcinoma in situ is not recommended.
