Inquiry Details
References:
WHO Class Female Genital Tumors, 188. 4th ed.
Question:
Solid Tumor Rules (2018)/Histology--Corpus uteri: What is the correct histology code for "Mesophrenic-like adenocarcinoma" of the corpus uteri?" See Discussion.
Discussion:
The article I read (https://www.ncbi.nlm.nih.gov/pubmed/?term=28984674) makes the distinction between mesophrenic adenocarcinoma and mesophrenic-like adenocarcinoma. The authors propose the term mesonephric-like Mullerian adenocarcinoma. So would this be coded as Mullerian adenocarcinoma?
Answer:
Assign code 9110/3, mesonephric adenocarcinoma. These tumors commonly arise in the cervical wall and more commonly involve the lower uterine segment than do other cervical adenocarcinomas.
