Solitary Fibrous Tumor in the Preperitoneal Space Mimicking an Intra‑abdominal Tumor
摘要
Solitary fibrous tumors (SFTs) are uncommon fibroblastic mesenchymal neoplasms that rarely metastasize. They were primarily considered intrathoracic tumors; however, recent studies have reported SFTs in extrathoracic locations. This report describes a rare case of an SFT in the preperitoneal space that mimicked an intra‑abdominal tumor radiographically. A 67‑year‑old woman was diagnosed with an extrahepatic tumor through ultrasonography. Computed tomography revealed a nodule near the liver’s left lobe at the upper abdominal midline. Laparoscopic tumor resection was performed to minimize undersampling and tumor seeding. Laparoscopy revealed a well‑circumscribed tumor located in the preperitoneal space. The tumor was resected en bloc with a macroscopically negative margin. Histopathological examinations confirmed an SFT using immunohistochemistry. Adjuvant treatment was not administered. No residual lesions were reported at the 6‑month and 1‑year follow‑ups. Although SFT rarely metastasizes, early diagnosis and treatment of SFTs should be emphasized to ensure optimal patient outcomes.
