摘　　要：BACKGROUND Sarcomatoid carcinoma of the pancreas(SCP)is a rare type of pancreatic neoplasm,and only a few cases have been described in the literature.Histologically,it is composed mostly of atypical spindle cells with apparent sarcomatous features.CASE SUMMARY This is a report of a 61-year-old Chilean woman who underwent medical investigation for acute abdominal pain.Computed tomography identified a solid tumor in the tail of the pancreas with features suspicious of malignancy.En-bloc distal pancreatectomy and splenectomy were performed to excise the tumor.Histopathology and immunohistochemistry were confirmatory of sarcomatoid carcinoma with lymphovascular invasion.After surgery,the patient did not receive chemotherapy.Previous studies indicate a poor prognosis for this type of malignancy.However,our patient has survived for 35 mo with no recurrence to date.CONCLUSION The case presented herein is a patient with an SCP with a rare presentation and long-term survival after surgery despite not receiving adjuvant chemotherapy.
