A Giant Intra-Abdominal Plasmablastic Neoplasm Favoring Lymphoma Mimicking an Exacerbation of Severe Fistulizing Crohn's Disease: A Case Report. (PubMed, Am J Case Rep) - Oct 10, 2026 - "CASE REPORT A 44-year-old woman with severe fistulizing Crohn's disease treated sequentially with adalimumab, infliximab, and ustekinumab developed progressive systemic deterioration despite partial intestinal stabilization. CONCLUSIONS Discordance between apparent intestinal control and systemic deterioration should prompt urgent tissue diagnosis. The findings favor PBL within the spectrum of plasmablastic neoplasms but neither establish drug-specific causation nor definitively exclude plasmablastic myeloma."
