Solitary fibrous tumors (SFTs) rarely occur in the central nervous system (CNS). Involvement of the brainstem and pineal gland is rarely recorded. Herein, we represent 2 cases of SFTs and firstly report SFT of the pineal gland. Cranial MR imaging showed isointense to hypointense signal intensity, and marked enhancement. Microscopically, the tumors showed characteristic “patternless-pattern” arc...
With the exception of well-differentiated liposarcoma, dedifferentiated leiomyosarcoma, solitary fibrous tumour, malignant peripheral nerve sheath and undifferentiated pleomorphic sarcoma, majority ≈70 histologic subtypes retroperitoneal sarcoma are defined as ‘ultra-rare’ sarcomas, with an incidence ≤1–5/1,000,000 persons/year. For most these ultra-rare RPS subtypes, diagnosis treatment follow...
BACKGROUND Solitary fibrous tumor is a rare spindle cell tumor and has been forced at a variety of sites. To the best of our knowledge, only two cases of solitary fibrous tumor arising in the spinal cord have been reported; no cytologic findings were documented. CASE A 62-year-old male presented with a spinal cord tumor. A scrape smear of the resected tumor revealed naked, spindle-shaped nucl...
Solitary fibrous tumors are uncommon spindle cell neoplasms originally thought to be restricted to the pleura.

At thoracotomy, a 10.5 x 6.5 x 5.5 cm, circumscribed, firm mediastinal mass demonstrated no direct cardiac or pulmonary involvement. The tumor consisted of spindle cells organized in a patternl...
