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.

Solitary fibrous tumor are rare and benign, soft tissue growth of any part of the human body including orbit and eyes. This case report describes a middle age female presented with a slow-growing painless mass in the superior orbital sulcus in the left eye. The lesion was surgically excised revealing the microscopic features characteristic of solitary fibrous tumor, with immunohistochemically reactivity for CD34 and STAT6 stains. Solitary fibrous tumor (SFT) is typically cured with complete surgical excision and CD34 immunohistochemistry proved to be a useful adjunct to the microscopic diagnosis of this type of tumor. doi: https://doi.org/10.12669/pjms.35.6.1086 How to cite this:Hayat N, Afzal MM, Dembra V.

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 (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.

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.

Extrapleural Solitary Fibrous Tumor

Solitary fibrous tumor is an uncommon mesenchymal neoplasm that very rarely appears in extra serosal soft tissue. Though pleural solitary fibrous tumor is more common, up to one third of the reported cases were at extra pleural sites. Although pleural and extrapleural solitary fibrous tumors are regarded as indolent tumors, there is some evidence that extrapleural subgroup could be a subset of more aggressive malignant tumors. Accurate preoperative diagnosis of extrapleural solitary fibrous tumor is very difficult and usually is a diagnosis of exclusion. Surgical excision is mandatory and is the best therapeutic option. In this article we report a case of solitary fibrous tumor of the chest wall in a 2 months old boy.J. Paediatr. Surg. Bangladesh 4(1): 28-31, 2013 (January)

Fibrous Tumor

Solitary fibrous tumors are uncommon spindle cell neoplasms originally thought to be restricted to the pleura. We describe a 62-year-old woman who presented with stridor and an anterior mediastinal mass. At thoracotomy, a 10.5 × 6.5 × 5.5 cm, circumscribed, firm mediastinal mass demonstrated no direct cardiac or pulmonary involvement. The tumor consisted of spindle cells organized in a patternless pattern with collagenous stroma and hemangiopericytoma-like vessels. Spindle cells were immunoreactive for CD34, CD99, desmin, vimentin and bcl-2 protein and a diagnosis of mediastinal solitary fibrous tumor was confirmed. The differential diagnosis of mediastinal solitary fibrous tumors is extensive and includes spindle cell thymoma, sarcomatoid carcinoma, malignant mesothelioma, inflammatory myofibroblastic tumor, peripheral nerve sheath tumors and various sarcomas. Despite their rarity in the mediastinum, solitary fibrous tumors can be recognized by their classic patternless morphology and immunophenotypic pattern. Their accurate classification is important, as solitary fibrous tumors are intermediate (rarely metastasizing) neoplasms that require complete surgical excision and long-term clinical follow-up for optimum therapy.

AbstractExtrapleural solitary fibrous tumor-hemangiopericytoma is a rare tumor. We present a case of this tumor arising in omentum, which is an extremely rare site. The diagnosis was confirmed by diffuse expression of STAT6 on immunohistochemistry. The tumor was assigned a low-risk category according to recent risk categorization models. The patient was advised close follow-up as the tumor was excised completely. These tumors have the potential for recurrence and metastasis even after surgical excision. However, there are no definitive guidelines for adjuvant treatment due to lack of data.

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.

Solitary fibrous tumors of the pleura (SFTP) are rare mesenchymal neoplasms that originate from mesenchymal growth in the pleura, tend to be single tumors, usually have an indolent course and show nonspecific symptoms. SFTP can be often diagnosed from an incidental finding of a single mass in the thorax and should be confirmed by biopsy and immunohistochemistry. A minority of cases may present Doege–Potter syndrome (DPS, episodes of refractory hypoglycemia) associated with production of insulin-like growth factor 2 (IGF-2). Both SFTP and DPS are rare occurrences with less than 2000 cases reported worldwide. The curative treatment is tumor resection. Two cases of patients with DPS caused by SFTP are presented below.

Extrapleural Solitary Fibrous Tumor

Abstract Extrapleural solitary fibrous tumors have often been confused with other mesenchymal tumors, such as hemangiopericytoma, fibrous histiocytoma, fibrous meningioma, and leiomyoma, because of morphologic similarity and underrecognition, especially if some unusual features are present. Recently, epithelioid solitary fibrous tumor has been reported in the mediastinum. We report a case of solitary fibrous tumor of the orbit with biphasic architecture, including spindle cell and epithelioid components. Both components demonstrated immunohistochemical features of a solitary fibrous tumor. A background of scattered vessels was present. No evidence of significant nuclear atypia or mitotic activity was noted. In this report, we discuss the differential diagnosis of solitary fibrous tumor with unusual epithelioid features. Extrapleural solitary fibrous tumor should be included in the differential diagnosis of tumors of the orbit with a spindle cell appearance even in the presence of some epithelioid morphology.
