Pancreatic metastasis from undifferentiated pleomorphic sarcoma. An extremely rare entity

Undifferentiated pleomorphic sarcoma (UPS) is a very aggressive malignant tumor that originates in bone or soft tissues, being its most frequent location in the extremities.We present the case of a 71-year-old man who, two years of follow-up after a lower right limb UPS excision surgery, presented a single metastasis of sarcomatoid origin in the pancreas that was treated by cephalic pancreaticoduodenectomy. Sarcomatoid metastases to the pancreas are extremely rare.Resection of the metastasis is the only therapeutic alternative that has reported benefit in terms of the survival of these patients.
