Inquiry Details

WHO Class Endocrine Tumors, 191. 2004
Question:
Reportability: Is a low-grade neuroendocrine neoplasm with gastrin expression found in a periportal lymph node reportable if the clinical impression is compatible with a gastrinoma? See Discussion.
Discussion:
SINQ 20110095 states that "low-grade neuroendocrine neoplasm/carcinoid tumor with expression of gastrin" is reportable. However, in this case "carcinoid tumor" is not mentioned. Is this case reportable if the expression "carcinoid tumor" is missing in the diagnosis of the pathology report? Also, does the fact that the gastrinoma was found in a lymph node affect reportability?
Answer:
This is a reportable case. Code the histology as malignant gastrinoma [8153/3].
Gastrinomas are usually malignant. This one is apparently present in a metastatic site (periportal lymph node) which confirms the malignancy.
