Goblet cell adenocarcinoma is a rare malignant tumour that is typically seen in the vermiform appendix.[1]
It has gone by a number of different names in the past: crypt cell carcinoma, goblet cell carcinoid[2][3] and neuroendocrine tumour with goblet cell differentiation.
General
- Rare appendiceal tumour that typically has an aggressive course vis-a-vis other appendiceal carcinoids.[2]
- Mixed (biphasic) tumour with endocrine and exocrine features.
- Usually presents as acute appendicitis.[3]
- Less common presentations: appendiceal mass, pain.
- Five year survival in one series: 60-85%.[3]
Gross
- Typically no mass is apparent at gross.[3]
Note:
- Should be submitted in total.
Microscopic
Features:[3]
- Mixed neuroendocrine-nonneuroendocrine tumour;[4] features of both carcinoid and adenocarcinoma.[3]
- Archictecture: cells arranged in nests or clusters without a lumen.
- Location: deep to the intestinal crypts (crypts of Lieberkühn); usually do not involve the mucosa.
- Cytoplasm distended with mucin.
- DNA: crescentic nucleus (similar to in signet ring cells).
- +/-Multi-nucleation.
- +/-High mitotic rate.
- Usually minimal nuclear atypia.
DDx:
- Appendiceal neuroendocrine tumour.
- Signet ring cell carcinoma[5] - cells more detached, no neuroendocrine differentiation.
- Poorly differentiated adenocarcinoma - see colorectal carcinoma.
