Specifically, octreotide has been shown to be efficacious in reducing the debilitating diarrhea and flushing episodes associated with metastatic carcinoid tumors
According to the American Society of Clinical Oncology, about 12,000 people in the US are diagnosed with a carcinoid tumor
5,7) The diagnosis of carcinoid tumors
is often difficult because of their low incidence and vague symptomatology.
Indeed, textbooks and literature reviews about submucosal gastric tumors usually include GISTs, leiomyomas, metastasis, schwannomas, heterotopic pancreatic tissue and carcinoid tumors
as possible lesions.
These included enterobiasis, schistosomiasis, mucocele, trichuriasis, tuberculosis, ascariasis, Endometriosis, mucinous cyst adenoma, granuloma, carcinoid tumor
, neuroma, clonorchiasis, primary adenocarcinoma and secondary carcinoma.
Carcinoid syndrome, characterized by intermittent flushing, diarrhea and wheezing, is present in 5% to 7% of carcinoid tumors
originating in the small bowel.

In contrast to carcinoid tumors
, small cell carcinomas have high-grade features, including tumor cells with scant cytoplasm, nuclear molding, brisk mitotic activity, apoptotic cell death, and extensive necrosis, none of which were seen here.
Other types of cancers common to the region include: intestinal carcinoid tumors
, cervical cancer, colorectal cancer, gastric cancer, Hodgkin lymphoma, Lynch syndrome, cutaneous malignant melanoma, head and neck squamous cell carcinoma, and others.
