Endoscopic Progression of Gastric DLBCL in an HIV-Positive Patient: A Case Report and Literature Review

This case highlights the critical importance of early upper gastrointestinal endoscopy in the follow-up of gastric lesions in HIV-positive patients, demonstrating how timely endoscopic monitoring serves as an essential tool to accurately assess the therapeutic effectiveness of antiviral and antitumor treatments. Direct visualization of the lesions' response enables prompt adjustment of therapy, significantly improving clinical outcomes. Moreover, the optimal management of such complex cases necessitates close multidisciplinary collaboration among hematologists, gastroenterologists, and infectious disease specialists. This interdisciplinary synergy is key to ensuring an integrated approach that enhances diagnostic precision, therapeutic strategies, and follow-up protocols, ultimately aiming to optimize patient outcomes and quality of life.
