Synchronous primary neoplasms of Meckel's diverticulum and colon malignancies are rarely reported in the literature. We present three patients with synchronous primary neoplasms of Meckel's diverticulum and colon malignancies. All tumors located in Meckel's diverticulum were incidentally found at laparotomy and the definitive diagnosis was made with microscopic examination of surgical specimens. Synchronous primary neoplasms of Meckel's diverticulum and colon malignancies are rarely encountered. Moreover, this is the first case of synchronous colon cancer and pancreatic intraepithelial neoplasia (PanIN) arising from pancreatic heterotopia within Meckel's diverticulum. The diagnosis of Meckel's diverticulum should be kept in mind in patients who underwent laparotomy for any reason; when found incidentally at laparotomy, it should be carefully examined for any suspicious abnormality and surgery should be considered that it can be performed without any problems.

Purpose: To assess the diagnostic performance of hemoglobin concentration for Meckel's diverticulum (MD) and evaluate if hemoglobin levels could be useful in the surgical decision-making process of children with lower gastrointestinal bleeding (LGIB).

Methods: Retrospective cohort study of children with LGIB attending the emergency department between 2011 and 2021. Episodes of LGIB were divided into two groups: MeckD (MD diagnosed by surgery) and non-MeckD.

Unlabelled: The RASopathies are a group of disorders resulting from a germline variant in the genes encoding the Ras/mitogen-activated protein kinase pathway. These disorders include Noonan syndrome (NS), cardiofaciocutaneous syndrome (CFC), Costello syndrome (CS), Legius syndrome (LS), and neurofibromatosis type 1 (NF1), and have overlapping clinical features due to RAS/MAPK dysfunction. In this study, we aimed to describe the clinical and molecular features of patients exhibiting phenotypic manifestations consistent with RASopathies.

Traumatic abdominal wall hernia (TAWH) is a rare but serious condition resulting from blunt abdominal trauma, characterized by the herniation of bowel or abdominal organs through a disrupted musculature and fascia without skin penetration. This report describes a unique case of a 24-year-old man who sustained a high-velocity blunt abdominal injury from a motorcycle handlebar during a road traffic accident. The clinical presentation, diagnostic challenges, surgical intervention, and postoperative recovery are discussed to emphasize the importance of the early recognition and management of TAWH in trauma patients.

In children, 90% cases of intussusception are idiopathic and the remaining 10% are attributed to underlying diseases (most commonly due to Meckel's diverticulum, polyps then either duplication cyst or mesentery cysts, and rarely due to Burkitt's lymphoma). The occurrence of acute intestinal intussusception caused by Burkitt's lymphoma in children under the age of 5 is exceedingly rare. Burkitt's lymphoma presents with diverse clinical manifestations, often leading to the identification of an abdominal tumor in pediatric patients.
