Gastrointestinal symptoms
When lymphoma is associated with the lymph nodes of the mesentery (GALT and MALT), it can lead to symptoms in the gastrointestinal tract due to pressure and luminal obstruction, intestinal tissue ischemia and necrosis.
For instance, pressure on the intestines can be a cause of constipation. Lymphomas in the Waldeyar ring can lead to dysphagia. Lymphoma of parotid gland is associated with the Sjogren syndrome, which features parotid swelling, xerostomia (dry mouth) and xeropthalmia (dry eyes).
MALToma of the stomach is strongly associated with Helicobacter pylori infection of the stomach, which can present as heartburn, indigestion, and epigastric pain. Compression of the structures in the abdomen can also lead to ascites (fluid in the abdominal cavity). Finally, a mediastinal DLBL can cause compression of esophagus and leads to dysphagia. In severe cases, it can lead to peritoneal effusion.
