Challenges in diagnosing and managing cystic duct carcinoma: A case report from Syria

INTRODUCTION AND IMPORTANCEPrimary cystic duct carcinoma, an uncommon and aggressive biliary cancer variant, poses a significant challenge in clinical practice. This study examines recent clinical cases, focusing on diagnostics, interventions, and implications in managing this disease, with a prevalence ranging from 0.03 % to 0.05 %, contributing to 2.6-12.6 % of extrahepatic biliary neoplasms.CASE PRESENTATIONA 57-year-old male, a smoker with hypertension and hyperuricemia, presented symptoms of severe upper right abdominal pain, jaundice, and altered stool color. Diagnosis revealed ulcerated papillary adenocarcinoma invading all gallbladder layers (2.5 cm). Surgical resection and Roux-en-Y anastomosis were performed. Histopathological examination showed invasive tumor proliferation, preserved lymph node architecture, and severe hepatic microsteatosis. Lymph nodes were tumor-free, and a benign hepatic biopsy (0.5 cm) displayed chronic portitis. The final diagnosis confirmed cystic duct carcinoma, emphasizing the complex diagnostic and therapeutic aspects in biliary cases.CLINICAL DISCUSSIONThe clinical discussion unveils the complexities associated with primary cystic duct carcinomas. Emphasizing the necessity of a multidisciplinary approach, this case highlights the importance of efficient management strategies-from initial diagnosis to surgical intervention-in dealing with this challenging malignancy.CONCLUSIONIn conclusion, this case underscores the intricate nature of primary cystic duct carcinomas. It accentuates the essential role of a multidisciplinary approach, urging the need for continuous research endeavors to further comprehend and enhance the treatment methodologies for this rare and complex malignancy.
