Intracranial solitary fibrous tumors are rare, and intraventricular fibrous tumors are even more unusual. We report a case of solitary fibrous tumor in the region of trigone and body of the left lateral ventricle and discuss the clinical presentation, CT characteristics, and histopathologic features with 1-year follow-up. We speculate that the tumor arose from the perivascular connective tissue...

A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisio...

INTRODUCTION First described by Von Recklinghausen in 1891, fibrous dysplasia is a developmental defect of osseous tissue such that bone is produced with an abnormally thin cortex and marrow is replaced with fibrous tissue that demonstrates characteristic ground-glass appearance on x-ray examination. The underlying defect in fibrous dysplasia is a mutation of the GNAS1 gene, which leads to cons...

This study focuses on the formation of lesions of atherosclerosis in the aortas and iliac arteries of nonhuman primates (Macaca nemestrina) maintained on a low level hypercholesterolemic diet (plasma cholesterol 200 to 400 mg/dl) for 2, 3, or 3.5 years. Advanced lesions, or fibrous plaques, were found in all of the animals. The extent and severity of the lesions were closely related to the leve...

normal bone marrow is replaced with fibro-osseous tissue. Patients are often asymptomatic, and fibrous dysplasia is often detected incidentally in patients with malignancy in whom F-fluoro-2deoxy-glucose positron emission tomography (F -FDG PET/ CT) is performed for metastatic disease. PET/CT findings of fibrous dysplasia have been reported on several papers. The level of FDG uptake in fibrous ...

Clinical, endocrinological and computed tomographic features of three patients with unusual manifestations or complications of craniofacial involvement of fibrous dysplasia are presented. One patient with polyostotic fibrous dysplasia presented in late pregnancy with acute onset of bilateral optic nerve compression and blindness secondary to a rapidly expanding mass of fibrous dysplasia tissue ...

Tissue engineering aims at resolving problems such as donor shortage and immune rejection faced by transplantation. Scaffolds (artificial extracellular matrices) have critical roles in tissue engineering. Recently, we developed nano-fibrous poly(L-lactic acid) scaffolds under the hypothesis that synthetic nano-fibrous scaffolding, mimicking the structure of natural collagen fibers, could create...

Fibrous papules of the face are hamartomas characterized by stellate-shaped stromal cells, multinucleated giant cells, and proliferative blood vessels in the dermis. The pathogenesis of fibrous papules remains unclear. There is a striking microscopic resemblance between fibrous papules and tuberous sclerosis complex (TSC)-associated angiofibromas. A germline mutation of the TSC1 or TSC2 gene, l...

BACKGROUND We present the extremely rare case of a 67-year-old male with malignant fibrous histiocytoma, arising in the lumbar spine, demonstrated with radiological and pathological studies. CASE REPORT The patient and his relatives refused open surgical approach and we performed transpedicular vertebral corpus biopsy and vertebroplasty under spinal anesthesia. His pathological result was mal...

Peritoneal encapsulation is an exceedingly rare developmental abnormality in which the small intestine is encased in an accessory peritoneal sac between the omentum and mesocolon. Two clinical signs associated with the dense fibrous layer encapsulating the intestine are described. The first is a fixed, asymmetrical distension of the abdomen, which does not vary with peristaltic activity due to ...
