Overview

Primary gastric lymphoma is cancer derived from lymphocytes (a type of white blood cell) that originates in the stomach.[1][2]

Most common cause of primary gastric lymphoma is mucosa-associated lymphoid tissue (MALT) lymphoma and diffuse large B-cell lymphoma (DLBCL) of the stomach. These account for 90% of all diagnosed cases. Lymphomas originating outside the lymph nodes are referred to as extra nodal lymphoma. Primary gastric lymphoma is the most common type of extra nodal lymphoma.

Primary gastric Lymphoma is a rare condition Gastric lymphoma accounts for less than 15% of gastric malignancies and about 2% of all lymphomas. Most of the primary gastric lymphomas are B cell non-Hodgkin lymphoma(NHL).

Classification

Pathophysiology

Histopathology

Most of the gastric lymphomas are predominantly non-Hodgkin’s lymphoma of B-cell origin. Primary gastric lymphoma can vary from being well-differentiated, low-grade lymphomas to high grade or large cell lymphomas.[3]


Primary Gastric Lymphoma

Clinical presentation

Symptoms

Common symptoms of primary gastric lymphoma include:[4][5]

Less common symptoms include :

Physical Examination

Differential Diagnosis

Gastric lymphoma must be differentiated from conditions with similar presentation like acute gastritis, chronic gastritis, atrophic gastritis, Crohn's disease, gastroesophageal reflux disease, peptic ulcer disease, gastrinoma and gastric adenocarcinoma :[6][7][8][9][10][11][12][13][14]

Natural History, Complications and Prognosis

Diagnosis

An endoscopic ultrasound (EUS) will help assess the depth of lymphoma invasion and involvement of perigastric nodes. MALT lymphoma presents as superficial spreading or diffuse infiltrating lesion whereas diffuse large B cell lymphoma has a typical mass forming lesion appearance on endoscopic ultrasound. Imaging investigations including CT scans or endoscopic ultrasound are useful to stage disease. Hematological parameters are usually checked to assist with staging and to exclude concomitant leukemia. An elevated LDH level may be suggestive of lymphoma.
