Abstract
BACKGROUND
A sclerosing epithelioid fibrosarcoma (SEF) is a rare malignant fibroblastic soft tissue tumor that rarely occurs in intra-abdominal organs. A case of a SEF in the pancreatic head is reported herein, including its clinical manifestations, preoperative imaging features, gross specimen and pathological findings.
CASE SUMMARY
A 33-year-old male patient was admitted to Peking Union Medical College Hospital in December 2023 due to a one-year history of intermittent upper abdominal pain and the discovery of a pancreatic mass. The patient underwent an enhanced computed tomography scan of the abdomen, which revealed a well-defined, round mass with clear borders and calcifications in the pancreatic head. The mass exhibited progressive, uneven mild enhancement, measuring approximately 6.6 cm × 6.3 cm. The patient underwent laparoscopic pylorus-preserving pancreaticoduodenectomy. Postoperative pathological examination revealed that the lesion was consistent with a SEF. At the 3-month postoperative follow-up, the patient did not report any short-term complications, and there were no signs of tumor recurrence.
CONCLUSION
SEFs are rare malignant fibrous soft tissue tumors. SEFs rarely develop in the pancreas, and its preoperative diagnosis depends on imaging findings, with confirmation depending on pathological examination and immunohistochemistry. Currently, only four cases of pancreatic SEF have been reported in studies written in English. This case is the first reported case of a pancreatic SEF by a clinical physician.
Core Tip: Sclerosing epithelioid fibrosarcoma (SEF) is a rare malignant fibroblastic soft tissue tumor, which is extremely rare in intra-abdominal organs. This article reports a case of SEF in the pancreatic head, presenting its clinical manifestations, preoperative imaging, gross specimen and pathological findings.
