Multiple primary carcinoma (MPM) refers to simultaneous or successive occurrence of ≥2 types of primary malignant tumors in a single organ or in different organs of the same individual. It is rarely seen in clinical practice. Among the various types of MPM, hilar cholangiocarcinoma combined with gastric cancer is extremely rare. The patient was a 61-year-old man who was admitted to our hospital due to upper abdominal discomfort and yellow-stained skin mucosa for 9 days. Preoperative diagnosis: Considering the typical preoperative painless jaundice as well as his clinical imaging report, the patient received the following preoperative diagnosis: obstructive jaundice, type IV hilar cholangiocarcinoma based on Bismuth-Corlette classification, and no intrahepatic distant metastasis. Intraoperative diagnosis: The results of intraoperative snap freezing and laboratory examination indicated gastric adenocarcinoma. Therefore, the patient received an intraoperative diagnosis of obstructive jaundice, hilar cholangiocarcinoma, and gastric cancer. Postoperative pathological diagnosis: Postoperative pathological examination of the gastric lesion revealed the following results: ulcerative, moderately differentiated gastric adenocarcinoma and intestinal type in the Lauren classification of stomach cancer; moderately differentiated adenocarcinoma of the bile duct. Surgical resection operation was carried out and the patient received chemotherapy after operation. But we could not strictly follow the relevant clinical guidelines to perform standardized operations and provide comprehensive treatment because of his economic situation, psychological factors, and the current medical environment in China. The patient did not receive standardized postoperative therapy. Although he lived and worked normally for 8 months after the operation, he died 10 months after surgery. This report reminds us to pay close attention to the likelihood of MPM and other low-incidence diseases. The physicians and imaging clinicians should explore all clinical possibilities to avoid misdiagnosis of this rare disease and formulate effective treatment plans to maximize the therapeutic benefits for the patient.
