We have performed this study to define the usefulness of an anti-human progenitor cell antigen-1(anti-CD34) to distinguish some kinds of soft tissue tumors in formalin-fixed, paraffin-embedded tissues. Sixty three cases of vascular, fibrohistiocytic, neural and other tumors were immunostained for CD34 using the streptavidin-biotin immunoperoxidase method. All of the vascular tumors including he...

Title:Determinants of outcome of solitary fibrous tumors of the pleura: an observational cohort study

Solitary fibrous tumor is a rare, benign spindle cell neoplasm that was first described in the thoracic pleura. This tumor is now known to occur at many extrapleural sites. There are established criteria for the diagnosis of malignant solitary fibrous tumor including ≥4 mitotic figures per 10 high-power fields, increased cellularity, cytologic atypia, infiltrative margins, and/or necrosis. Alth...

Solitary fibrous tumor (SFT) of the pleura is a rare an unknown cause and corresponds to 5% all pleural tumors. It generally asymptomatic discovered incidentally through imaging exams. The definitive diagnosis based on histopathological findings treatment surgical. This paper describes case previously healthy female patient with mass at base left lung.

Solitary Fibrous Tumors (SFTs) are rare primary pleural neoplasms which have recently been reported in extra-thoracic sites. In this report, solitary fibrous tumor arising in an intra-thoracic goiter with no evidence of cervical mass in a 74-year-old obese man who was found to have a large superior mediastinal mass with tracheal deviation on Chest X-Ray is presented.

Solitary fibrous tumors are benign spindle-cell neoplasms, mostly originating from the visceral pleura. They are common in individuals aged 20-70 with no sex predilection. To our knowledge, this is the unique case of the solitary fibrous tumor originating from the accessory parotid gland in the literature.

The solitary fibrous tumors (SFT) are rare tumors in the head and neck region and there have been only 5 cases reported in the literature in the soft palate. The current paper presents a unique case of a 62-year-old male with TFS arising in the soft palate. The tumor was highly cellular, composed of bland looking haphazardly arranged spindle cells. The signal transducer and activator of transcr...

Bone and soft tissue malignancies account for a small portion of brain metastases. In this review, we characterize their incidence, treatments, and prognosis. Most of the data in the literature is based on case reports and small case series. Less than 5% of brain metastases are from bone and soft tissue sarcomas, occurring most commonly in Ewing's sarcoma, malignant fibrous tumors, and osteosar...

Introduction: Desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   Case Report: The patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. His CT-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. Biopsy was compatible with desmoid fib...

Rationale: Solitary fibrous tumors (SFTs) are rare spindle cell tumors that are most commonly found in the mediastinal pleura. Although there are increasingly more reports of extra-pleural SFTs, reports of SFTs in bone are very rare. To our knowledge, a SFT of the ilium has not yet been reported. With low specificity on computer tomograpy and magnetic resonance imaging, SFTs are easily misdiagn...
