Summary
Extranodal lymphoma can occur outside lymph nodes, often in the gastrointestinal tract. This case highlights a rare primary colorectal lymphoma diagnosis of diffuse large B-cell lymphoma in a patient previously treated for Burkitt lymphoma.
Area of Science:
- Oncology
- Gastroenterology
- Hematology
Background:
- Extranodal lymphoma involves non-lymph node sites, frequently the gastrointestinal tract.
- Primary colorectal lymphoma is an uncommon malignancy of the colon.
Observation:
- A patient with a history of Burkitt lymphoma in remission presented with a large cecal mass.
- The cecal mass indicated a new diagnosis of diffuse large B-cell lymphoma.
Findings:
- The patient was diagnosed with diffuse large B-cell lymphoma, a type of extranodal lymphoma.
- This diagnosis occurred despite a history of Burkitt lymphoma remission.
Implications:
- This case underscores the importance of vigilance for secondary malignancies or recurrence in lymphoma survivors.
- It highlights the diagnostic challenges and management considerations for rare colorectal lymphomas.

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

The large intestine is where the final stages of digestion happen. When the cecum receives chyme, it contains undigested carbohydrates that undergo fermentation. Gut bacteria ferment these carbohydrates to produce short-chain fatty acids that provide some energy and help synthesize essential vitamins.
As the chyme moves to the colon, it triggers two characteristic sluggish contractions - haustral churning and mass peristalsis. Haustral churning involves the rhythmic contraction and relaxation...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
