Objectives: Analyze clinic and epidemiological aspects of all Oral Granular cell tumor (GCT) during a 5-year period in a Brazilian population. Study design: clinical and treatment outcome data of patients with oral GCT seen at the Division of Stomatology, School of Dentistry, Federal University of Ceara, Brazil, between January 2001 and December 2005 were reviewed. Results: during the analyzed ...

OBJECTIVE Multiple therapeutic modalities exist for giant cell tumors (GCT) in the distal radius. The majority of GCTs are amenable to curettage, with the expanded lesions requiring a more radical approach. This case report examines the technique of managing a GCT that has extended beyond the boundaries of the cortex and into local tissues. The decision to use arthroplasty versus arthrodesis an...

Giant cell tumor (GCT) of the sphenoid bone is a relatively rare entity and metachronous multicentric GCT of the sphenoid is even rarer; we are aware of only 3 previous cases in the literature. We describe here a tumor of the sphenoid bone that was identified 15 years after multiple resections of a GCT of the left inferior pubic ramus. Correlation is made between the histopathologic findings, M...

Paget's disease of the bone may predispose the development of malignant bone tumors such as osteosarcoma. Giant cell tumor (GCT) as a consequence of Paget's disease is rare. Bone GCT is characterized by rapid growth, the destruction of bone, extension to the surrounding soft tissue and abnormal bone turnover caused by an abnormality of the receptor activator of nuclear factor-κB (RANK)-RANK lig...

In late December 1990, a new radio source appeared near the center of our galaxy rivaling the intensity of Sgr A(*) (the compact radio source at the galactic center). Following its first detection, the flux density of the galactic center transient (GCT) increased rapidly to a maximum 1 month later, and then declined gradually with a time scale of about 3 months. Surprisingly, the GCT maintained...

Granular cell tumor (GCT) is a benign tumor of the breast that can mimic, on breast imaging, invasive carcinomas. Biological evolution of mammary GCT is unknown, especially if it is associated with an invasive carcinoma in the same or contralateral breast. This report details the morphological features of these synchronous lesions highlighting their biological characteristics and suggesting an ...

Geometric complexity theory (GCT) is an approach to the P vs. NP and related problems through algebraic geometry and representation theory. This article gives a high-level exposition of the basic plan of GCT based on the principle, called the flip, without assuming any background in algebraic geometry or representation theory.

Granular cell tumours (GCT) of the soft tissues are rare benign tumours but some time may be difficult to distinguish from malignant neoplasms. It is important that clinicians are aware of their existence. We present a new case of GCT of the soft tissues followed by a brief review of literature.

Giant cell tumours (GCT) of the bone are benign, but locally invasive tumours. We present a new case of carpus GCT, involving the triquetrum. The diagnosis required a prior biopsy before doing the block resection. This treatment is the best option to avoid recurrences. We review the literature on this particular lesion in the carpus bone.

A giant cell tumor of soft tissue (GCT-ST) is a rare composed mononuclear and osteoclast-like multinucleated cells. It low-grade malignant potential morphologically analog to bone. The superficial deep extremities the most frequent site this which cured by complete or radical resection. GCT-ST as primary in female Breast exceedingly rare. Presentation cells breast has been described association...
