A 23-year-old man was diagnosed with Crohn's disease (CD) of the large intestine after colonoscopy revealed longitudinal ulcers, and pathology revealed non-caseating epithelioid cell granulomas and anal fistulas. The CD relapsed, and therefore prednisolone (PSL) and infliximab (IFX) treatment was initiated. The PSL was gradually tapered.

There has been noteworthy progress in molecular characterisation and therapeutics in soft tissue sarcomas. Novel agents have gained regulatory approval by the FDA. Examples are the tyrosine kinase inhibitors avapritinib and ripretinib in gastrointestinal stromal tumours (GIST), the immune check point inhibitor atezolizumab in alveolar soft part tissue sarcoma, the γ-secretase inhibitor nirogacestat in desmoid tumours, the NTRK inhibitors larotrectinib and entrectinib in tumours with fusions, the mTOR inhibitor nab-sirolimus in PEComa, and the EZH-2 inhibitor tazemetostat in epithelioid sarcoma.

Purpose: MAK683, a first-in-class and highly selective allosteric inhibitor of the embryonic ectoderm development subunit of polycomb repressive complex 2, has shown sustained antitumor activity in tumor xenograft models. This first-in-human phase 1/2 study evaluated the safety, pharmacokinetics (PK), and clinical activity of single-agent MAK683 in advanced malignancies.
Methods: MAK683 was administered fasted once daily or twice daily continuously in 28-day treatment cycles.

Background: Sarcomatoid carcinoma of the small bowel is an exceedingly rare gastrointestinal tumor characterized by a biphasic cellular pattern of epithelioid and mesenchymal-like cells. Due to its rarity and non-specific clinical presentation, it is frequently misdiagnosed, and there is a lack of standardized management guidelines. We report a case of multiple sarcomatoid carcinoma of the small intestine, presenting initially with gastrointestinal perforation.

Neoplasms are only sporadically reported in New World primates and rarely in owl monkeys (), specifically. Previous reports of neoplasms in owl monkeys are primarily restricted to lymphoma induced by infection, although other tumors in the central nervous, genitourinary, gastrointestinal, and endocrine systems have been sporadically reported. Herein, we describe 3 previously unreported neoplasms in owl monkeys () including a pericardial mesothelioma in a 6-year-old male, a nephroblastoma in a 2-year-old male, and a cervical neoplasm with characteristics of an epithelioid trophoblastic tumor in a 4-year-old female, all occurring in the same closed breeding colony at a research facility in central Texas.
