Metastasis: Fibrosing Local Lymph Nodes Lesion
Cancers are sorted by a combination of rarity, overall frequency of metastases, and predilection for this site.
| Cancer | Frequency | Comments |
| Gastrointestinal Carcinoid | Common |  Fibrosis (desmoplastic reaction) can cause kinking of bowel and obstruction. Often the mesenteric lymphadenopathy may be larger than the primary tumor, in the case of small intestine primaries. Around 70% of mesenteric lymph node metastases contain calcification. |
