Treatment of Rare and Aggressive Pancreatic Carcinosarcoma.

A 42-year-old African American woman presented with 4 days of worsening midepigastric pain that radiated to her back. Computed tomography confirmed a diagnosis of acute pancreatitis and revealed a mass within the distal body and tail of the pancreas. After an endoscopic ultrasound with fine-needle aspiration yielding atypical cells suspicious for adenocarcinoma, the patient underwent an en bloc resection of the intra-abdominal mass with subtotal pancreatectomy, splenectomy, left colectomy, and left partial adrenalectomy. Histopathologic examination findings, in addition to immunohistochemical staining, revealed a diagnosis of pancreatic carcinosarcoma. Postoperatively, the patient has undergone 20 cycles of chemotherapy and has been transitioned to comfort measures at 16 months postoperatively because of progressive disease.
