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 ce...

The papular variant of elastolytic giant cell granuloma (EGCG) is a rare EGCG, and it occasionally associated with metabolic comorbidities, including diabetes mellitus (DM). Although the mechanisms developing EGCG are still unknown, one possible for ECGC in DM patient might be explained by hyperglycaemia-induced inflammation. In this report, we described case interstitial mainly composed matrix...

 ABSTRACT Background: Cholesterol cleft granulomas with clusters of giant cells were noted to be a common feature of non-specific interstitial pneumonia (NSIP). Objective: This study aimed to define the cell populations involved in the granulomas. Methods: The granulomas of 16 patients with cryptogenic fibrosing alveolitis (five cases with the histological features ofNSIP, five with those ofUIP...

Granuloma annulare (Gan) and giant cell arteritis (GCA) share common histologic features. In Gan, a disease characterized by the presence of palisading granulomas usually in the dermis, the main alteration is the presence of elastic fiber degeneration and it strongly suggests that the primary target leading to the development of this disorder is the injury to the elastic tissue. On the other ha...

Giant cell reparative granulomas (GCRG) are non-neoplastic rapidly expanding and locally destructive lesions typical of facial skeleton bones. Jaffé first described these lesions in 1953, designating benign lesions of the jaw that were histologically different from true giant cell tumors of long bones. Mandibular GCRG area rare lesions, comprising less than 7% of all benign bone lesions of the ...

Peripheral giant cell granuloma (PGCG) is a non-neoplastic lesion representing a local hyperplastic reaction. It is a tumorlike pathologic condition arising on the buccal or lingual attached gingival or alveolar mucosa and the crest of the edentulous alveolar ridge, of uncertain etiology; it is probably a reactive lesion caused by chronic local irritants or trauma rather than a true neoplasm. P...

The case report is of a 30 year old male, who complained of a slowly expanding swelling in the maxilla in the left premolar region. The swelling was clinically and radiographically diagnosed as Central Giant Cell Granuloma. The patient also had Angles Class 2 Division 2 Malocclusion in which repeated micro trauma may have possibly contributed to the formation of the tumor. The tumor was surgica...

Discussion Giant cell reparative granuloma is an uncommon lesion that is a reactive process and not a neoplasm. At histologic analysis, giant cell reparative granulomas demonstrate plump, bland fibroblasts and multinucleated giant cells surrounding foci of hemorrhage; osteoid production along hemorrhagic foci is commonly seen. The histologic appearance of GCRG is similar to that of brown tumor ...

Annular elastolytic giant cell granuloma (AEGCG) is a rare granulomatous skin disease of unclear pathogenesis which belongs to the group of disorders in the skin and elastic fibers with similar clinical features of granuloma annulare (GA). This case report is intended to describe a rare hybrid pattern in histopathology demonstrating coexistence of AEGCG and GA. An endocrine disease, such as dia...

Purpose. Implant therapy plays an important role in contemporary dentistry with high rates of long-term success. However, in recent years, the incidence of peri-implantitis and implant failures has significantly increased. The peripheral giant cell granuloma (PGCG) rarely occurs in peri-implant tissues and it is clinically comparable to the lesions associated with natural teeth. Therefore, the ...
