Case of Primary Carcinosarcoma as an Extremely Rare Cancer of Gallbladder

Seyhan Yalaz, Serap Karaarslan, Aynur Solak, Atİlla ÇÖkmez, Hasan Kaplan


Introduction: Gallbladder carcinosarcomas (GBCS) are a rare type of gallbladder malignancies. These tumors are characterized by interlaced epithelial and mesenchymal components.

Presentation of Case: The experience with diagnosis and follow-up of these cancers is limited because of the number of patients diagnosed with this tumor is so small and the tumor has a poor prognosis. Therefore, we present the following case report to share our experience with a 13-month survival of a 55-year-old woman presenting with right flank pain and jaundice who underwent laparoscopic cholecystectomy with an initial diagnosis of chronic cholecystitis and later diagnosed with GBCS.

Conclusion: GBCS have  poor survival rate even with successful surgical therapy due to unclear etiopathogenesis, extremely very low incidence, and lack of consensus regarding its follow-up and treatment.
