central giant cell granuloma (cgcg), formerly called giant cell reparative granuloma, is a non-neoplastic proliferative lesion of unknown etiology. it occurs most commonly in the mandible. the case reported here resembled a wide variety of conditions that led to a misdiagnosis both on clinical and radiographic examinations but was histopathologically diagnosed as cgcg. we describe a case of cgc...

Background:  Giant cell tumor of tendon sheath (GCTTS) is often thought of as a volar finger mass. We hypothesized that GCTTS are equally common on the dorsal and volar aspects of the hand. In addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a GCTTS.  Methods:  A total of 126 patients with a pathological dia...

Objective: The purpose of this study was to retrospectively analyze the demographic characteristics of patients with central peripheral giant cell granulomas (CGCGs) / (PGCGs) an Iranian population. Methods: In this 38-year retrospective study, the data were obtained from records of 1019 patients with CGCG and PGCG of the jaws referred to the Department of Oral and Maxillofacial, Pathology, ...

  Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal ...

A four-year-old male Persian cat was referred with three weeks history of progressive lameness due to a rigid osseous mass with 3.50×2.50×2.00 cm in dimensions in his left arm. In the histopathological evaluation of bone biopsy, two distinct populations of cells including multinucleated giant cells and oval cells which embedded in a fibro-osseous stroma and surrounded by lamellar bone trabecula...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 there are a few case series of giant cell tumor (gct) in the spine and sacrum. gct in the thoracic vertebrae is even more exceptional in the medical literature. in this article we report a gct in a 25-year-old male who presented with progressive back pain and dyspnea. on contrast-enhanced multidetector computer tomography,...

The malignant transformation of conventional giant cell tumor of bone (GCTOB) is rare and usually occurs with irradiation. Here we report two neglected cases of conventional GCTOB with spontaneous malignant transformation at 11 and 16 years after initial diagnosis. In the former case, the patient refused to receive any treatment following the incisional biopsy, and in the latter, the firs...
