Question:

MP/H Rules/Histology--Endometrium: What is the correct histology code for an endometrial cancer described as "Adenocarcinoma with areas of squamous differentiation?"

Discussion:

Answer:

Assign 8570/3 to adenocarcinoma with squamous differentiation of the endometrium. The most recent WHO classification does not list "adenocarcinoma" for tumors of the uterine corpus. WHO does state that "endometroid carcinoma of the usual type is a glandular neoplasm..." Further, WHO states "Endometroid carcinoma typically displays a glandular or villoglandular architecture..." Based on the WHO classification, the use of the term "adenocarcinoma" in this context can be interpreted as endometroid carcinoma.
