Inquiry Details
References:
ICD-O-3, 66
Question:
Reportability--Ovary: Is micropapillary serous carcinoma (MPSC) of the ovary reportable? What are the differences between “noninvasive" and “low malignant potential?" See discussion.
Discussion:
Pathology report reads left ovary: noninvasive low grade (micropapillary) serous carcinoma (MPSC), fragmented; right ovarian excrescence and posterior cul-de-sac: noninvasive implants identified; right ovary: noninvasive low grade (micropapillary) serous carcinoma (MPSC), scattered autoimplants (noninvasive); tumor is present on ovarian surface, noninvasive autoimplants
Answer:
Noninvasive low grade (micropapillary) serous carcinoma (MPSC) of the ovary is reportable. Assign code 8460/2, applying the ICD-O-3 matrix concept to this noninvasive carcinoma. Noninvasive can be used as a synonym for in situ, ICD-O-3 behavior code /2. See page 66 in the softcover ICD-O-3. Low malignant potential (LMP) means that the neoplasm is not malignant, but has some chance of behaving in a malignant fashion. LMP can be used as a synonym for ICD-O-3 behavior code /1, see page 66.
