Primary Follicular Lymphoma of the Gastrointestinal Tract: Case Report and Review.
OBJECTIVE
Primary gastrointestinal follicular lymphoma (GI-FL) is considered a rare disease with fewer than 400 cases reported in the literature. It accounts for roughly 1-3 % of GI non-Hodgkins lymphomas (NHL). It originates in the GI tract and typically affects small bowel. The disease has an indolent course, and a prolonged survival can be expected in most cases. Due to its rarity, an optimal diagnostic work up and treatment plan has not been well established.


METHODS
Endoscopic evaluation of the entire gastrointestinal (GI) tract using esophagogastroduodenoscopy (EGD), wireless capsule endoscopy, double-balloon enteroscopy, colonoscopy, and whole body examination with fluorodeoxyglucose-positron emission tomography (FDG-PET) has been suggested to more accurately stage the disease and guide the treatment plan.


RESULTS
Treatment options for GI follicular lymphoma include watch and wait strategy, surgery, chemotherapy, radiation, immuno-radiotherapy, or a combination of these modalities.


CONCLUSIONS
In this article, we have summarized the existing information regarding clinical presentation, diagnostic evaluation, and treatment options for this rare entity after presenting a case of GI-FL who was diagnosed during an EGD for evaluation of belching, heartburn, and weight loss.
