Solitary fibrous tumour of the infratemporal fossa

Abstract

Solitary fibrous tumour was first described as a pleural tumour. It has been reported in a number of extrapleural sites including the head and neck. We present the first case of solitary fibrous tumour of the infratemporal fossa described in the English literature. Complete excision was achieved using the orbitozygomatic infratemporal craniotomy approach.

Solitary Fibrous Tumor of the Orbit: CT and MR Imaging Findings

“…Although most occur in the parietal or visceral pleura or peritoneum, they can arise from other extrapleural sites, including the mediastinum; lung; liver; breast; retroperitoneum; spine; meninges; and extracranial head and neck region such as the orbit, sinonasal cavity, salivary gland, thyroid gland, upper aerodigestive tract, infratemporal fossa, buccal space, and parapharyngeal space. [2][3][4][5][6][7] On microscopic examination, SFT is a well-circumscribed, nonencapsulated tumor that shows a patternless arrangement of alternating hypercellular and hypocellular regions of spindle cells against a collagenous background of variable vascu- larity. In some cases, a focal hemangiopericytoma-like pattern of irregular branching vessels, fibrous histiocytoma-like storiform pattern, and synovial sarcomatous and neural-like pattern of palisading regional architecture are seen.…”

“…It can also arise in the extracranial head and neck region such as the orbit, sinonasal cavity, salivary gland, thyroid gland, upper respiratory tract, and deep cervical spaces. [2][3][4][5][6][7] Since the first report of 2 cases of orbital SFT in 1994, 8 the orbit has become one of the common sites of the head and neck involved by the tumor, and more than 50 cases of orbital SFT have been reported mostly in the ophthalmologic and pathologic literature. [9][10][11][12][13][14][15][16][17][18][19][20][21] To our knowledge, however, systematic analysis of the imaging features of orbital SFT has seldom been reported in the radiologic literature.…”

Solitary fibrous tumor of the parotid gland extending to the parapharyngeal space

“…These tumors often arise in the pleura [1], but can be found in various head and neck sites. Although rare, these locations have included the infratemporal fossa [12], parapharyngeal space [13], nose and paranasal sinuses [3,16], soft palate [14], epiglottis [13], as well as the thyroid [15], parotid [5,8,14] and submandibular gland [7,14]. We now report a case of SFT arising from the parotid gland and extending to the parapharyngeal space.…”

Solitary fibrous tumor of the infratemporal fossa: A case report

“…Many recent immunohistochemical and ultrastructural studies argue strongly in favour of mesenchymal cell origin which is supported by the occurrence of solitary fibrous tumor in locations away from serosal surface 2,3 . Rayappa 4 et al reported the first case of solitary fibrous tumor of the infratemporal fossa (IFT) in 1996. Here we report the second case of solitary fibrous tumor arising in infratemporal fossa which was excised completely through transmaxillary approach.…”
