Abstract
Bowel obstruction is an uncommon clinical presentation in Burkitt´s lymphoma, specially in adults. This type of lymphoma is classified within B-cell non-Hodgkin´s lymphomas, which is characterized by its aggressiveness and quickly tumoral growth. The clinical presentation related to the gastrointestinal tract is unusual, but it can be presented as intussusception, obstruction or ischemic perforation. Here we describe a case of Burkitt´s lymphoma with bowel obstruction as a clinical debut.

Abstract
Following the incidental finding of a tumor in a 58-year-old female, diagnosed as pancreatic lipoma, histologically confirmed by fine-needle aspiration biopsy (FNAB) with endoscopic ultrasound (EUS), we made a review in our center between 2018 and 2020, with 14 cases diagnosed of pancreatic lipoma by computarized tomography (CT) or magnetic resonance imaging (MRI).

Abstract
Donor-recipient size mismatch in liver transplantation is a recognized but uncommon situation. It can lead to a partial or complete obstruction of the inferior vena cava with subsequent hepatic outflow obstruction. Placement of a breast implant in the right upper quadrant of the abdomen during liver transplantation is a technically easy resource and can protect the liver graft from kinking or rotation.

Abstract
The intestinal epithelium is very peculiar for its continuous cell renewal, fuelled by multipotent stem cells localized within the crypts of Lieberkühn. Several lines of evidence have established the evolutionary conserved RNA-binding protein Musashi1 as a marker of adult stem cells, including those of the intestinal epithelium, and revealed its roles in stem cell self-renewal and cell fate determination. Previous studies from our laboratories have shown that Musashi1 controls stem cell-like features in medulloblastoma, glioblastoma, and breast cancer cells, and has pro-proliferative and pro-tumorigenic properties in intestinal epithelial progenitor cells in vitro. To undertake a detailed study of Musashi1's function in the intestinal epithelium in vivo, we have generated a mouse model, referred to as v-Msi, overexpressing Musashi1 specifically in the entire intestinal epithelium. Compared with wild type litters, v-Msi1 mice exhibited increased intestinal crypt size accompanied by enhanced proliferation. Comparative transcriptomics by RNA-seq revealed Musashi1's association with gut stem cell signature, cell cycle, DNA replication, and drug metabolism. Finally, we identified and validated three novel mRNA targets that are stabilized by Musashi1, Ccnd1 (Cyclin D1), Cdk6, and Sox4. In conclusion, the targeted expression of Musashi1 in the intestinal epithelium in vivo increases the cell proliferation rate and strongly suggests its action on stem cells activity. This is due to the modulation of a complex network of gene functions and pathways including drug metabolism, cell cycle, and DNA synthesis and repair.
