Intrapulmonary location of benign solitary fibrous tumor

摘要

Intrapulmonary solitary fibrous tumors (SFTs) are sporadic mesenchymal neoplasms that typically arise from visceral or parietal pleura. While accounting for 5% of all pleural tumors, SFTs are known to occur in nearly all bodily organs, including nasopharynx, bladder, prostate, soft tissue of neck, buttocks, extremities, and abdominal wall. Such tumors have been previously designated localized fibrous mesothelioma or pleural fibroma. SFTs have no genetic basis and are unrelated to environmental factors such as tobacco smoking or asbestos exposure. Herein, we describe a 24-year-old woman whose clinical presentation mimicked atypical carcinoid tumor. A diagnosis of intrapulmonary SFT was achieved by surgical resection.
