Inquiry Details

#2: WHO Class Digest System Tumors, 202-204. Anal squamous dysplasia
Question:
Reportability--Anal Canal: Is a 2021 diagnosis of moderate squamous dysplasia (AIN II) of the anal canal reportable? See Discussion.
Discussion:
We are aware that squamous intraepithelial neoplasia, grade II (e.g., AIN II), 8077/2 is reportable for 2021. However, because this is also called rather than high grade squamous dysplasia (8077/2), we are unsure about reportability. There is no known histology and behavior code for moderate squamous dysplasia, the classifications available are only low grade (8077/0) or high grade (8077/2).
Answer:
If possible, clarify with the pathologist/physician what is meant by "moderate squamous dysplasia (AIN II)."
If no further information can be obtained, report this case based on the diagnosis of "AIN II." Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable for cases diagnosed in 2021. AIN is a type of squamous intraepithelial neoplasia.
