“…However, this is not always a statement proven by the presented cases, but rather information gained from the cited references, included in the discussion part of the articles. 3 , 5 , 6 , 8 , 9 If concerning the airway in general HPC's of the nasal cavity and trachea are characterized by a symptomatic course of 3 months to 2 years before diagnosis. The tracheal HPC re-grew to a symptomatic tumor after 5 months.…”

“…The tumor shows isoattenuation (relative to the muscle) with enhancement after intravenous contrast injection, on CT imaging. Low attenuation intra-lesional areas were reported to be associated with myxoid or cystic degeneration [41]. On MRI imaging, SFT is iso-intense (relative to the muscle) on T1-weighted images, whereas T2-weighted images can show both homogeneous and heterogeneous enhancement, depending on the different number of fibroblasts and collagen in the tumor composition [44,45].…”

“…Therefore, tumors originally diagnosed as both laryngeal SFT (61%) and HPC (39%) have been considered in the present review [8,9,14-41] (Table 1). Laryngeal HPC shares with SFT the prevalent supraglottic location, clinical presentation, small size, and treatment strategies [30][31][32][33][34][35][36][37][38][39][40][41].…”

The present review is based on a critical literature revision and aimed to identify the overall clinical behavior of laryngeal solitary fibrous tumor (SFT). Laryngeal hemangiopericytomas (HPC) were included, according to both their re-classification as the SFT's cellular variant and the NAB2-STAT6 fusion gene. A case series was builded including a new case and other 30 previously published cases of laryngeal SFTs (Medline 1956 to 2021) with comparative purpose. Immunohistochemistry and molecular analysis were performed on the new case. The clinical features of such case series showed a peculiar behavior of SFT, characterized by 1) Early symptomatic onset 2) Small size at diagnosis 3) Prevalent supra-glottic location 4) Impairment of the quality of voice with vocal muscle sparing 5) Favorable clinical outcome after complete surgical excision, since no distant metastases were reported in the literature. Furthermore, atypical histologic features were infrequently described. As seen in the pleural counterpart and in other extra-pleural locations, laryngeal SFT harboured NAB2-STAT6 gene fusion and showed a strong nuclear immunostaining for STAT6, as confirmed by the herein described case. According to its peculiar clinicalpathologic behavior, the risk stratification models that have been proposed for SFT are not suitable for the larynx.
