Background: Solitary fibrous tumors (SFTs) are benign tumors derived from mesenchymal tissues that predominantly occur in the pleura. Establishing the diagnosis of these very rare intramedullary spinal lesions, with no clear-cut pathognomonic radiographic characteristics, is particularly challenging. Case Description: Two males, 30 and 41 years of age, presented with progressive cervical myelopathies attributed to a cervical intramedullary exophytic tumor with associated spinal cord edema. One patient showed that the lesion was highly vascularized. Both patients underwent surgical excision of firm, solid, focal, and, particularly in one of them, very vascular/hemorrhagic tumors; at surgery, there was some adherence between the tumors and the cord tissue, but gross-total resections were achieved in both cases, demonstrated on postoperative MR scans. Histological and immunohistochemical findings confirmed the diagnosis of SFT (WHO Grade I). After a 6-month postoperative period, both patients neurologically improved and had no MR evidence of tumor recurrence. Conclusion: Intramedullary cervical exophytic SFTs are extremely rare. Although these solid tumors may present with hemorrhagic features and at surgery demonstrate significant adherence to the pial/cord surface, complete surgical resections are feasible resulting in good outcomes.

Abstract Solitary fibrous tumors are relatively rare mesenchymal neoplasms that were originally described as pleural- or peritoneal-based lesions. Although they were considered a form of mesothelioma, subsequent investigation failed to reveal mesothelial differentiation. Characterization of their histologic and immunohistochemical features, as well as identification in a multitude of nonmesothelial-based locations has further served to distinguish these lesions from the more diffuse and aggressive mesothelioma. Reports of solitary fibrous tumor in the larynx are extremely rare. We report a case of solitary fibrous tumor of the larynx in a 38-year-old man.

Fibrous Tumor

Solitary fibrous tumors are uncommon spindle cell neoplasms generally associated with serosal surfaces, especially the pleura. Recently, these tumors have been documented in a number of extrapleural sites including the head and neck. So far only two cases of parapharyngeal solitary fibrous tumor have been reported in the English literature. Rare location of an uncommon lesion often gives rise to difficulty in diagnosis or to misdiagnosis. In both the previously reported cases, as well as in our case, the diagnosis of solitary fibrous tumor was not made until the excised tumor was subjected to histopathology and immunohistochemistry.

Fibrous Tumor

Solitary fibrous tumors (SFTs) are rare mesenchymal tumors, originally identified in the pleura. Even though they have subsequently been described in several extrapleural sites, the incidence of SFTs in the spermatic cord is particularly rare. Here, we report a case of a 27-year-old male that presented with a 3-year history of left scrotal swelling. Computed tomography (CT) and ultrasound demonstrated multiple solid, hypoechoic well-circumscribed masses that were separate from the testis. Surgical excision of the mass led to pathologic diagnosis of a solitary fibrous tumor involving the spermatic cord. Solitary fibrous tumors, although rare, are an important differential diagnosis for urogenital tumors.

Abstract Renal solitary fibrous tumors (SFTs) have been reported infrequently. We report a 76-year-old man with a left renal mass that had previously been shown radiographically to be stable, but was now growing. Grossly, the mass measured 12 cm, was poorly circumscribed, and invaded beyond the renal capsule. Approximately 10% of the neoplasm consisted of haphazardly arranged spindle cells admixed with dense collagenous bands, which is typical of benign SFT. However, the remainder of the mass was composed of pleomorphic, spindled sarcoma cells with frequent mitoses and foci of necrosis. Immunohistochemically, we observed CD34 labeling in the benign SFT component with loss of expression in the sarcomatous component, focal labeling for Bcl-2 protein in both areas, and absence of labeling for cytokeratin, renal cell carcinoma marker, S100 protein, CD117, and muscle markers in both areas. To our knowledge, this is the first reported case of malignant renal SFT, likely representing transformation from a histologically documented benign SFT component.

Solitary fibrous tumors are uncommon mesenchymal neoplasms that were initially described as pleural tumors, but in recent years, numerous extrapleural sites have been reported. A solitary fibrous tumor is characterized as a circumscribed, painless mass with a patternless growth pattern, positive CD34 spindle-shaped cells, bcl-2, and dense keloidal collagen with areas of hypercellularity and hypocellularity. This case report describes a 55-year-old male veteran who presented with a rare manifestation of an extrapleural solitary fibrous tumor of the medial right hallux. Microscopic and immunohistochemical findings were consistent with the previously documented characteristics of solitary fibrous tumors. Complete surgical excision of the tumor is the treatment of choice.

Space Case

Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a rare neoplasm arising from spindle cells and most commonly arising from pleura. Spinal SFT/HPC is a rare entity; hence, it is not on the top of the differential diagnosis list when a clinician faces a spinal lesion. In the review of the literature, there exist less than 50 case reports of intradural extramedullary SFT/HPC. Here, we present a 54-year-old female patient who underwent subtotal surgical excision of an intradural extramedullary spinal mass pathologically reported to be SFT/HPC and had symptomatic recurrence in the 3rd year of follow-up. Surgical intervention was unachievable and the patient was given 45 Gy to the surgical cavity followed by a 5.4 Gy boost to visible tumor with external radiotherapy. Patient reported significant relief of her symptoms. We aim to contribute to the formation of a treatment algorithm for this rare entity.

Introduction: Solitary fibrous tumor is a neoplasm of mesenchymal origin with benign and malignant forms. We aimed to present a case of solitary fibrous tumor which developed in a patient operated for laryngeal cancer and originated from diaphragm in the light of the literature. Case report: A 61-year-old male patient with tracheostomy with an undiagnosed lesion that appears to be almost 10 cm was referred to our clinic. Since it was a large volume mass, we chose to perform a thoracotomy over thorachoscopic approach. Discussion: Although solitary fibrous tumors most commonly occur in the pleura but may also originated from diaphragm, and our case is valuable that originates from diaphragmatic since there are less than 5 reported cases in literature for past two decades. Conclusion: Even in the case of recurrence, the main treatment remains as total surgical excision. Solitary fibrous tumors are usually detected because of compression symptoms. That is the main reason why we chose thoracotomy.

AbstractThe fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior although 12% of solitary fibrous tumors can be malignant and have worse outcomes. These tumors are considered “giant” when the lesion > 15 cm. Surgical treatment is the best choice for both benign and malignant neoplasms. We retrospectively analyzed the main case series of giant fibrous tumors of the pleura. In addition we report our experience of a 76-year-old woman treated by pre-surgical embolization involving implantation of vascular plugs. Surgery was successfully carried out without complications; imaging and functional assessment 6 months post intervention demonstrated both the absence of recurrence and improvement of lung function parameters.

Tumor Types

✓ Solitary fibrous tumor is a spindle cell tumor deriving from mesenchymal cells that arises most commonly in the pleura. Only very recently has this tumor been reported in the spine. A solitary fibrous tumor strongly resembles other spindle cell neoplasms of the spine and may be an unrecognized entity if not routinely considered in the differential diagnosis of spinal neoplasms. The authors report an unusual intra- and extramedullary location for a solitary fibrous tumor of the cervical spine. Findings in this case and a comprehensive review of the literature indicate that solitary fibrous tumors can originate from various spinal anatomical substrates and mimic both intra- and extramedullary tumor types.

Fibrous Tumor

First described as a pleural neoplasm, the solitary fibrous tumor has been reported in a number of extrapleural sites, including the upper respiratory tract. The neoplasm is of mesenchymal origin, exists in benign and malignant forms, and is a histopathologic diagnosis made after exclusion of other soft tissue neoplasms. None of the eight reported sinonasal and nasopharyngeal solitary fibrous tumors have been histologically or biologically malignant. Surgical excision appears to control the tumor at these sites.
