Question:

Tumor Size--Pathologic--Anus: In 2019, the pathology report of an anal canal squamous cell carcinoma stated the tumor size is 2.5 cm from proximal to distal (3.5 cm in circumference). Is the pathologic tumor size tumor size 025 or 035?

Discussion:

Answer:

Based on the information provided, code the tumor size as 035. We asked an expert pathologist to review this question and she said to use the larger measurement. She also said "the pathologist usually cuts the anus and rectum open like a tube; the “circumference” would be measured flat."
