Giant Solitary Fibrous Tumor from the Lesser Omentum Causing a Gastric Outlet Obstruction: A Case Report
並列摘要
Introduction: Solitary fibrous tumors (SFTs) are exceedingly rare tumors arising from the submesothelial mesenchymal layer. Case Report: A case of a 60-year-old male with paranoid schizophrenia presented with acute gastric obstruction secondary to a large, obstructive, mobile mass. Surgical exploration revealed a 17x15x10.5 cm extraluminal, pedunculated mass originating from the lesser omentum extrinsically compressing the gastric antrum and duodenum. The mass was surgically resected with immediate relief of patient symptoms. Pathology revealed a spindle cell sarcoma with a high mitotic index. Immunohistochemical analysis was positive for CD34 and a newly elucidated nuclear marker that is sensitive and specific for SFT, STAT 6, was used to confirm the diagnosis of SFT. Conclusion: To our knowledge, this is the largest described solitary fibrous tumor arising from the lesser omentum.
