Rare Coexisting Hepatocellular and Gallbladder Carcinomas: A Case Report.

Area of Science:

• Oncology
• Gastroenterology

Background:

• Multiple primary malignancies are uncommon but increasingly detected due to advanced imaging and regular check-ups.
• Distinguishing multiple primary tumors from metastasis is crucial for accurate diagnosis.
• Coexisting hepatocellular carcinoma and gallbladder carcinoma represent an extremely rare clinical scenario.

Purpose of the Study:

• To document and analyze a rare case of synchronous hepatocellular carcinoma and gallbladder carcinoma.
• To provide insights into the diagnostic and therapeutic management of double primary malignancies.
• To evaluate the effectiveness of curative resection and adjuvant therapy in improving overall survival.

Main Methods:

• Case report of a 64-year-old male patient.
• Diagnostic process including CT scan and definitive histopathologic examination.
• Surgical approach, preoperative biopsy, and adjuvant therapy details.

Main Results:

• Histopathology confirmed coexistence of hepatocellular carcinoma and gallbladder carcinoma, initially suspected as gallbladder wall infiltration.
• The patient underwent surgical resection and adjuvant chemotherapy.
• Overall survival and treatment outcomes were documented post-intervention.

Conclusions:

• Curative intent procedures are superior for managing double primary malignancies, with treatment strategy dependent on tumor type and stage.
• Exclusion of metastatic disease is critical, especially given the liver's susceptibility to metastasis.
• This case underscores the importance of documenting rare occurrences to guide effective therapeutic management and improve patient survival.
