Liver Granulocytic Sarcoma With Megakaryocytic Differentiation: A Rare Extra Medullary Involvement That Warrants Liver Biopsy for Prompt Diagnosis.

Granulocytic sarcoma (GS) is an extramedullary manifestation of acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) or myeloproliferative neoplasms. The diagnosis depends on morphology, immunohistochemistry and flow cytometry. An unusual location of this tumor may mask its primary source, therefore, a strategy involving immediate symptom control, and investigation is crucial in preventing clinical deterioration.

Role of regenerating islet-derived proteins in inflammatory bowel disease.

Inflammatory bowel disease (IBD) is an inflammatory disorder of the gastrointestinal tract that affects millions of patients worldwide. It has a complex and multifactorial etiology leading to excessive exposure of intestinal epithelium to microbial antigens, inappropriate activation of the immune system and ultimately to the damage of intestinal tissues.
