The article focuses on a case study of malignant insulinoma with multiple liver metastases, highlighting its rarity and challenges in treatment. Topics include the clinical presentation and diagnostic imaging of the patient, the treatment approach involving hepatic artery embolization, radiofrequency ablation, and everolimus, and the subsequent clinical outcomes and insights for managing similar cases.

Researchers at Peking Union Medical College Hospital in Beijing, China, have conducted a study on glucagonoma, a rare neuroendocrine tumor of the pancreas. Glucagonoma syndrome, caused by excessive secretion of glucagon by the tumor, often leads to necrolytic migratory erythema (NME), a skin condition. The researchers reported a case of a patient with glucagonoma syndrome who presented with recurrent erythema and scaling on the skin. After confirming the diagnosis, the patient underwent surgical resection of the tumor, leading to a rapid resolution of the skin eruptions. The study also reviewed relevant literature to provide clinicians with a better understanding of glucagonoma, including its clinical manifestations, laboratory and imaging examinations, diagnosis, and treatments.

Researchers from Peking University in Beijing, China have conducted a study on epithelioid gastrointestinal stromal tumors (GISTs), which are rare and can be mistaken for other tumors. The study analyzed the morphological, immunohistochemical, and genetic characteristics of 12 epithelioid GIST samples. The results showed that certain gene mutations, such as platelet-derived growth factor receptor alpha gene (PDGFRA) mutations, may play a significant role in the pathogenesis of co-mutant GISTs. The study provides valuable insights into the understanding of these tumors. [Extracted from the article]

A recent study conducted at Peking University Third Hospital in Beijing, China, has identified a novel genetic mutation associated with hereditary bilateral synchronous pheochromocytomas (PHEOs). The study focused on a Tibetan pedigree in which a father and son were diagnosed with PHEOs. Whole-exome sequencing revealed a heterozygous germline missense mutation in the adenomatous polyposis coli (APC) gene, which is typically associated with familial adenomatous polyposis and colorectal cancers. The findings suggest that this APC gene mutation may predispose individuals to PHEOs. Further research is needed to better understand the implications of this mutation. [Extracted from the article]
