Lymphoma B small cells of the Jejuno

 This 60 year-old male, presented with vomiting, abdominal
 pain, weakness, fatigue, and diarrhea and weigh lost of 20
 pounds, a cat scan of the abdomen showed a thickness of
 the omeantum with abdominal adenopathies with images
 of cat scan of segmental part of jejuno with thickness, at
 endoscopy shows a vegetal fiber impactation which cause
 small bowel obstruction due to a intestinal stenosis, the
 fiber were partially removed and fragmented with the
 diathermy loop.

Jejunal Lymphoma

20-30 cm after the angle of Treitz, there are neoplastic .

 Primary gastrointestinal non-Hodgkin lymphomas (NHLs)
 are a heterogeneous group of unique B- and T-cell
 lymphoid malignancies. Their pathology, clinical features,
 management, and prognosis may differ from lymphomas of
 lymph node origin. As an example, indolent lymphomas of
 lymph node origin are almost always disseminated at
 diagnosis, have frequent bone marrow involvement,
 generally respond to therapy, but continuously recur.
 Median survival can exceed 10 years, although cure is
 unusual.

Diffuse Small B-Cell Lymphoma Complicated With Jejunal Stricture

 Gastrointestinal lymphomas comprise a group of distinct
 clinicopathological entities. Differences in lifestyle and
 environmental factors between countries could account for
 the variety in the distribution of the main subtypes:
 low-grade B-cell lymphomas of the mucosa-associated
 lymphoid tissue type, alpha-chain disease and enteropathy
 (celiac disease)-associated T-cell lymphoma (EATL). The
 possibility of preventing these lymphomas implies a
 knowledge of their natural history together with an
 identification of potential predisposing factors.

 A narrowness of the jejuno is displayed in this image as well as the video clip.

The development of the lymphoid hyperplasia and subsequently low-grade lymphoma with the possibility of high-grade transformation is a multifactorial process involving both antigenic and host-related factors. The pathogenic role of Helicobacter pylori and gluten has been demonstrated in gastric lymphoma and enteropathy-associated T-cell lymphoma respectively, while environmental factors, especially non-specific bacterial ones, may play a major role in the pathogenesis of alpha-chain disease. The most difficult task in preventing these lymphomas is the recognition of early lesions likely to regress after the removal of the exogenous stimulus.

Narrowness and infiltrates due to this lymphoma

 Small intestinal tumors (tumors of the duodenum, jejunum,
 and ileum) are uncommon in comparison with those
 occurring elsewhere in the gastrointestinal tract. Although
 the small intestine is approximately 20 ft long, comprising
 75% of the length of the gastrointestinal tract and 90% of
 its mucosal surface area, less than 2% of malignant
 gastrointestinal tumors are derived from this organ.

Circular infiltration of jejunal wall with lymphoma. Patient was placed under chemotherapy.

 Primary small intestinal tumors are diverse in nature
 because they are derived from both epithelial and
 mesenchymal components of the small bowel. The most
 frequent histological types of primary malignant tumors
 include adenocarcinomas, carcinoids, lymphomas, and
 sarcomas (most are now classifi ed as gastrointestinal
 stromal tumors).
