B-Lymphoblastic Lymphoma of the Small Bowel: An Extremely Rare Occurrence

B-lymphoblastic lymphoma is a neoplasm of immature B cells and is characterized by aggressive behavior and disease progression. Common sites of involvement are skin, lymph nodes, bone, soft tissues, breast, and the mediastinum. Gastrointestinal lesions are rarely encountered and therefore not fully described. We herein report the case of a 28-year-old male, who presented with abdominal pain and CT scan showed a tumor involving the small bowel and its mesentery. He underwent emergency laparotomy and enterectomy. Histopathology report revealed B-lymphoblastic lymphoma affecting the small bowel and the adjacent mesentery. This is the first documented case of a small bowel tumor diagnosed as B-lymphoblastic lymphoma in published literature.

Small bowel malignant tumor: a diagnostic dilemma, a case report and literature review

A 47 years old Saudi male was admitted to king Khalid hospital with complaints of constipation and abdominal distension. Abdominal examination showed as a case of intestinal obstruction. He was fully evaluated and was treated first conservatively, until all investigative study confirmed as huge small bowel dilatation (mainly jejunum). Exploratory laparotomy confirmed small bowel tumor and on histology an adenocarcinoma. The introduction, history and research paper will also be discussed in this report.

Gastric heterotopia with perforation mimicking neoplastic process in ileum

Gastric heterotopia (GH) is rare in ileum except in Meckel’s diverticulum and rarely causes severe symptoms in adults. Here, we report a 31-year-old male patient with GH in ileum presented with bowel perforation and mass formation in the mesentery mimicking perforated small bowel tumor. Microscopic examination of the lesion showed completely differentiated gastric body-type mucosa with mucosal ulceration, fistula formation and bowel perforation. This case raises the awareness that GH may cause severe complications and should be included in the differential diagnosis for acute abdominal pain especially in patients with a mass lesion at an unusual location.

Update on small bowel surveillance in hereditary colorectal cancer syndromes

Despite its rarity in the general population, small bowel adenocarcinoma risk is increased in individuals with hereditary colorectal cancer syndromes (HCCS). In the last decade, the advent of capsule endoscopy and device-assisted balloon enteroscopy procedures in patients with HCCS have allowed to investigate the whole small bowel, increasing the diagnostic yield of small bowel tumor. Nonetheless, there is a significant variability in the international guideline recommendations. The aim of this review is to provide an update on surveillance of small bowel in HCCS and to identify the key points for the clinical management of these patients.
