Sun MQ, Guo LN, You Y, Qiu YY, He XD, Han XL. Sclerosing epithelioid fibrosarcoma of the pancreas: A case report. World J Clin Cases 2024; 12:5983-5989. [DOI: 10.12998/wjcc.v12.i26.5983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 07/02/2024] [Accepted: 07/10/2024] [Indexed: 07/19/2024] Open
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.

Abstract
Rare malignant mesenchymal pancreatic tumors are systematized and reported in this review. The focus is on the appearance on imaging. The present overview summarizes the data and shows that not every pancreatic tumor corresponds to the most common entities of ductal adenocarcinoma or neuroendocrine tumor.

Abstract
Sclerosing epithelioid fibrosarcoma (SEF) is an extremely rare subtype of sarcoma that appears histologically low-grade yet usually has a clinically aggressive course with a high rate of local recurrence and distant metastasis. However, these recurrences and metastases often occur years after initial treatment. Metastases can be to the lung as well as extra-pulmonary sites. In this case report, we discuss a patient who developed SEF in the deep soft tissue with metastases. This patient underwent checkpoint inhibitor therapy, with disease response. Thus, SEF is a sarcoma subtype with a unique tumor biology, and immunotherapy may be a promising avenue for treatment.

Abstract
BACKGROUND Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm generally affecting muscle tissue. It presents rarely in abdominal viscera and even more rarely occurs in the pancreas. All types of pancreatic sarcomas are uncommon, and LGFMS is a rarer still. We present the case of an LGFMS in the pancreas. Because of its rarity, there are no guidelines for appropriate treatment or summations of the natural course of this illness. CASE PRESENTATION We present the case of a 49-year-old female who presented with epigastric pain. She had a prior history of three episodes of acute pancreatitis many years earlier. A CT revealed a pancreatic body mass, which was biopsied. Pathology returned LGFMS. The patient underwent a distal pancreatectomy and splenectomy. She did well after the case and did not require further intervention. CONCLUSION Though it is exceedingly rare, cases of pancreatic LGFMS should be reported in order to guide clinical decisions. LGFMS has been shown to have high malignant potential in other tissues, and there is no reason to think pancreatic masses will be different. By building a body of evidence about these rare tumors, patient care will benefit.

Abstract
First described in 1995 by Meis-Kindbloom et al. as a variant of fibrosarcoma simulating carcinoma, sclerosing epithelioid fibrosarcoma (SEF) is a malignant soft tissue sarcoma characterized by epithelioid cells in dense sclerotic stroma, frequent immunoreactivity for MUC4 and heterogeneous genetic profile with recurrent EWSR1 gene rearrangement. It typically affects middle-age adults with a predilection for the lower extremity. It is believed that SEF is closely related to low-grade fibromyxoid sarcoma (LGFMS), both tumors show overlapping features in morphology, immunophenotype, and molecular profile. In this review, we discuss the clinical, morphologic, and immunohistochemical features of SEF with particular emphasis on its molecular diversity and relation to LGFMS.
