Intussusception is a common cause of bowel obstruction in the pediatric population. Malignant lesions account for up to 30 % of all cases of intussusception in the small intestine. We herein report an interesting case of ileo-colic intussusception caused by diffuse large B-cell lymphoma, in a child. The patient underwent laparoscopic right hemicolectomy. Pathologic evaluation revealed a diffuse large B-cell lymphoma.
In cases of intussusception, especially in the older age group of children, a high index of suspicion for malignant lymphoma of the bowel should be observed.
Intussusception, defined as the telescoping of a segment of the gastrointestinal tract into an adjacent one, is often seen in paediatric age . Gastrointestinal tumours, especially if they occur in the large bowel, cause intestinal intussusception in 63–68 % of cases . Intussusception caused by diffuse large B-cell lymphoma (DLBCL), as a cause of acute abdomen, is rare, and, often, intussusception represents the first clinical sign, leading, potentially, to disease detection at an early stage .
Primary malignant tumours of the small intestine are very rare, accounting for less than 2 % of all gastrointestinal malignancies . Lymphoma constitutes 15–20 % of all small intestine neoplasms . In particular, DLBCL, the most common form of non-Hodgkin lymphoma (NHL), is a heterogeneous entity rarely causing acute obstructive symptoms and intussusceptions . Intestinal involvement of NHL has been correlated to increased frequency of abdominal symptoms resulting in an earlier diagnosis. It was found that the invasion depth of the tumour is significantly associated with patient survival . DLBCL-patients initially undergo chemotherapy rather than surgery. Therefore, the relationship between surgery treatment and prognosis has not previously been reported. The importance of resection of the bowel containing even the smallest of lesions, along with removal of regional lymph nodes, is further stressed . Moreover, a multicenter study found that primary surgical resection was associated with a favourable prognosis in cases of intestinal DLBCL, encouraging surgical resection as primary treatment . Conversely, an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma has been also reported, especially of diffuse large B-cell lymphoma . Finally, there is no consensus on the optimal treatment against primary gastrointestinal DLBC [5, 6].
In conclusion, we describe a pediatric case of large B-cell lymphoma causing an ileo-colic intussusception. In cases of intussusception, especially in the older age group of children, a high index of suspicion for malignant lymphoma of the bowel, including DLBCL should be observed.
