Question:
Histology/Reportability/Behavior Code--Testis: Is a mature teratoma that is metastatic to lymph nodes reportable? See Description.
Discussion:
Pathology report states, "Histologic sections reveal lymph node metastases, consisting predominantly of mature teratoma. In addition, there are cells scattered through the fibrous stroma which exhibit mild cytologic atypia but have low N:C ratios. The largest metastasis grossly measures 10cm. In addition extracapsular extension is identified. Diagnosis: Lymph Nodes--Metastatic Testicular Carcinoma Involving Multiple Lymph Nodes." The morphology code for mature teratoma is 9080/0. The pathologist does not classify this as an immature teratoma (9080/3). Is this reportable?
Answer:
Yes, this metastatic teratoma is reportable.
This is a malignant teratoma by virtue of the lymph node metastases. Code the histology as 9080/3 [Teratoma, malignant, NOS]. Primary site is testis [C62_].
