Crypt cell carcinoma, also known as goblet cell carcinoid[1][2] and neuroendocrine tumour with goblet cell differentiation, is a rare malignant tumour that is typically seen in the vermiform appendix.
General
- Rare appendiceal tumour that typically has an aggressive course vis-a-vis other appendiceal carcinoids.[1]
- Mixed (biphasic) tumour with endocrine and exocrine features.
- Usually presents as acute appendicitis.[2]
- Less common presentations: appendiceal mass, pain.
- Five year survival in one series: 60-85%.[2]
Gross
- Typically no mass is apparent at gross.[2]
Microscopic
Features:[2]
- Mixed neuroendocrine-nonneuroendocrine tumour;[3] features of both carcinoid and adenocarcinoma.[2]
- 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).
- +/-Multinucleation.
- +/-High mitotic rate.
- Usually minimal nuclear atypia.
DDx:
- Appendiceal neuroendocrine tumour.
- Signet ring cell carcinoma - cell detached.
Images
CCC - very high mag. (WC/Nephron)
CCC - very low mag. (WC/Nephron)
Stains
- Mucin stains +ve:
- Mucicarmine, perodic acid-Schiff diastase (PAS-D), alcian blue.
IHC
- Classic neuroendocrine markers:
- Synaptophysin +ve.
- Chromogranin +ve.
- S-100 +ve.
- NSE +ve.
- Serotonin +ve.
Keratins:
- Usually CK20 +ve > CK7 +ve.
- CEA +ve (membrane).
Notes:
- Nice review of stains in Pahlavan and Kanthan.[2]
