Identification And Characterization

Solitary fibrous tumor (SFT) is a rare neoplasia of mesenchymal origin, initially described in visceral pleura and lately discovered to have ubiquitous distribution. SFT of the urogenital tract is uncommon and appears to have similar morphologic features and biologic behaviors as SFTs found elsewhere. We present two new cases of SFT of the bladder and review 22 similar cases published in the literature. Due to the general indolent behavior of these lesions, a complete but organ sparing surgical excision should be considered when technically feasible. Therefore, proper identification and characterization of SFT through morphological and immunohistochemical criteria on biopsy specimens are mandatory in the differential diagnosis from other more aggressive spindle-cell tumors, thus avoiding unnecessary radical surgery.

ABSTRACT Localized fibrous tumors of the lung arise from the visceral pleura and are pedunculated. They also project into the pleural cavity. The tumor with an entirely pulmonary location is extremely rare. We present here a rare case of intrapulmonary localized fibrous tumor with review of the literature.

Fibrous Tumor

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.

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.

Solitary fibrous tumor is an unusual spindle cell neoplasm that usually occurs in the pleura but has also been described in other sites. Renal presentation is rare and only 38 cases of SFT of the kidney have been described until now. Up to 90% of the tumors have benign characteristics. Local retroperitoneal recurrence is extremely rare. We report a case of a large malignant solitary fibrous tumor recurrence after the surgical excision of the primary tumor. Histological examination of the specimen confirmed the diagnosis by revealing highly positive reaction of the neoplasmatic cells for vimentin, CD34, bcl-2 and moderately positive for actin. The rate of Ki67 lied between 2–7%. No adjuvant therapy was given to the patient and he is disease-free with no imaging findings of recurrence or metastasis 9 months after the re-operation.

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

Solitary fibrous tumor is uncommon spindle cell mediastinal tumor arising mainly from pleural surface. Authors discuss a clinic-radiological features of Fat forming SFT which is rare variant of SFT in 70yrs old male patients. Initially we kept differential of Liposarcoma, Lymphoma on clinico-radiologically features but later after histopathology and Immunohistochemistery turns out to be Solitary fibrous tumor. Here accurate classification is important as SFT classified as intermediate type (rarely malignant), require wide surgical excision with close follow-up.

Abstract We report 2 cases of solitary fibrous tumor of the prostate. Histologically, both tumors demonstrated a multipatterned architecture with varying degrees of collagenization and hemangiopericytoma-like foci, and both were composed of CD34-immunopositive spindled cells that insinuated themselves between strips of collagen. The tumor in case 1 was well circumscribed and showed minimal mitotic activity or pleomorphism, whereas the tumor in case 2 was more cellular, less collagenous, had a more diffuse growth pattern, and exhibited cytologic atypia and high mitotic activity. Prostatic solitary fibrous tumor must be distinguished from other spindle cell tumors reported to occur in the prostate. To our knowledge, these cases represent only the fifth and sixth reported cases of prostatic solitary fibrous tumor.
