“…There has been an increasing incidence of the tumor in the extrapleural, extraserosal sites such as the lung, liver, breast, meninges and in the head and neck region [2]. The real incidence of SFTs of the orbit is not clear, but these tumors have been increasingly recognized ever Fig.…”

“…2 a, b MRI of the orbit showed an ill-defined, heterogenous mixed intensity lesion in the upper part of the left orbit involving the extraconal, conal and intraconal compartments since its initial description in 1994. The various locations of orbital SFT include the intraconal and extraconal spaces of the orbit, [2] lacrimal gland, lacrimal sac and eyelid. The tumour in our patient was found to be arising from the pigmented outer layer of pars plana of the ciliary body.…”

“…They are most commonly reported to arise from the pleura and also from various other extra-pleural sites, including the mediastinum, lung, liver, breast, retroperitoneum, spine, meninges and extra-cranial head and neck regions such as the orbit, sino-nasal cavity, salivary gland, thyroid gland and along the upper aero-digestive tract [2]. We describe the clinical presentation and further discuss the management challenges of a rare case of recurrent giant orbital SFT in a 15-year old girl along with a brief review of literature.…”

Solitary fibrous tumors (SFTs) are uncommon spindle-cell tumors of mesenchymal origin initially described in the pleura and subsequently in other extrapleural sites. These tumors are categorized as tumors of 'intermediate malignancy' under the World Health Organization classification of soft tissue tumors. SFT was virtually non-existent or misdiagnosed until its characteristic features, particularly the strong and diffuse immuno-reactivity to CD 34 were described. Extra-pleural manifestations of SFT, particularly in the head and neck region are rare. Although a number of isolated case reports of orbital SFTs have been described ever since its initial description in 1994, cases of recurrent SFTs have been very few. Recurrences of these tumors following surgery are considered unusual and metastasis exceptional. We describe clinical presentation and the management challenges of recurrent giant orbital SFT in a 15-year old girl along with a brief review of literature

“…Other tumors like schwannoma, neurofibroma and lymphoma show less noticable enhancement compared to SFT. 8 Major histopathological differential diagnosis of orbital SFT includes hemangiopericytoma, schwannoma, fibrous histiocytoma, leiomyoma, leiomyosarcoma and optic nerve sheath meningioma. Although they have overlapping morphological features, a clear distinction can be made among these tumors with immunohistochemical analysis.…”

Background: Solitary fibrous tumors (SFT) arising from the larynx are extremely rare; most occur in the supraglottic larynx. Case Report: Herein, we detail a new case of a subglottic SFT presenting as a well-encapsulated soft-tissue tumor with hoarseness. It showed isoattenuation, similar to the adjacent muscle on pre-contrast computed tomography (CT) images, and strong, heterogeneous enhancement following contrast material administration, which may reflect hypervascularity. On pathological examination, it consisted of spindle cells, squeezed between abundant collagen, and focally prominent vascularity in a staghorn feature. The tumor cells were immunoreactive for CD34, BCL2 and CD99. Based on the combination of architectural and immunohistochemical criteria, we ultimately diagnosed this case as an SFT. Conclusion: Until now, only 14 cases of laryngeal SFT have been described in the literature: 13 located in the supraglottic areas and only one located in the subglottic/tracheal area. Therefore the present case is the second case of a subglottic SFT reported. Although rare, SFT should be included in the differential diagnosis of a well-marginated laryngeal mass with highly intense contrast enhancement, which suggests rich tumor vascularity.

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

Abstract: BACKGROUND AND PURPOSE:Solitary fibrous tumor (SFT) is a rare spindle-cell neoplasm originating from mesenchymal fibroblast-like cells. The purpose of this study was to describe the CT and MR imaging features of SFTs in the orbit.
