A Case Report of the Coexistence of Gastric Cancer With Polycystic Kidney and Liver Disease: Unveiling the Complexity.

Polycystic kidney disease (PKD) is a genetic disorder that comprises multiple cystic lesions in the kidneys. The association of PKD with gastric cancer has been studied. We present a rare presentation of stomach cancer with polycystic liver and kidney disease. A male patient in his 40s presented with epigastric pain, nausea, retrosternal burning, and occasional episodes of vomiting. Esophagogastroduodenoscopy revealed ulceroproliferative growth in the prepyloric region. Biopsies revealed moderately differentiated adenocarcinoma which was confirmed by contrast-enhanced computed tomography of the abdomen and pelvis. This showed a chance finding of polycystic kidney and liver disease. After confirmation with a positron emission tomography scan, the patient was diagnosed with gastric carcinoma (cT3N1M0, Stage IIB) with polycystic kidney and liver disease. We provide a case of early-stage stomach cancer in a patient with PKD. More extensive research is needed for a better understanding of this association between polycystic kidney and liver disease and gastric cancer development, to achieve earlier diagnosis.
