We present two cases of central giant cell granuloma in the temporal bone. CT showed an enhancing tumor causing a smoothly margined temporal squamosa and floor of the middle fossa. External carotid angiograms showed tumor stain mainly supplied by the temporal branches of the internal maxillary artery. In one case, MR images showed a hypointense mass on both T1- and T2-weighted images that was t...

s: Central giant cell granuloma (CGCG) is an uncommon benign intraosseous lesion of the jaws accounting for approximately 7% of all benign tumors of the jaws. The traditional treatment of CGCG is surgical removal. However, the extent of tissue removal ranges from simple curettage to en bloc resection and reconstruction. This article describes a massive yet nonaggressive type of central giant ce...

Central giant cell granulomas are non-neoplastic lesions of unknown etiology. They affect females more than males with the mandibular anterior region being the most common site of occurrence. Clinically central giant cell granulomas present as asymptomatic, expansile swellings causing deviation of associated teeth. Radiologically they usually presents as multilocular lesions causing expansion o...

Background and Importance Giant cell granuloma (GCG) is a rare, benign, non-neoplastic lesion of the head and neck. More common in the jaw bones, there have been few reports of the lesion arising in the temporal bone. Initially referred to as a "giant cell reparative granuloma," due to the previously accepted notion of its nature in attempting to repair areas of injury, the term "giant cell gra...

Introduction: Giant cell granulomas (GCGs) of the jaws are lesions that arise either peripherally in periodontal ligament, mucoperiosteum, or centrally in the bone. Histologically, both peripheral and central giant cell granuloma (CGCG) are characterized by the presence of numerous multinucleated giant cells (MGCs) in a prominent fibrous stroma. CGCG are further categorized into aggressive and ...

Peritoneal keratin granuloma is a rare lesion included under granulomatous lesions of the peritoneum. It can be of infectious and non-infectious etiology. The lesion presents as a large intra-abdominal necrotic mass often misinterpreted clinically as a disseminated carcinoma. We report a case of peritoneal keratin granuloma in a 50-year-old male following peritonitis. Histomorphology revealed l...

A case of a rare giant cell lesion of a tarsal bone, giant cell reparative granuloma, is presented with CT correlation. CT is useful in pre-operative management both in defining the extent of involvement of adjacent structures and demonstrating soft tissue abnormality.

INTRODUCTION Peripheral giant cell granuloma and peripheral ossifying fibroma are clinicopathologically distinct gingival lesions. Both are included in clinical differential diagnoses of common benign and reactive gingival epulides in humans. It is often impossible to make a clinical distinction between the two entities, thereby making definitive diagnosis dependent on histopathologic features....

Background and aims. The correlation between morphology of giant cells in peripheral granulomas of the jaws and the aggressive behavior of the lesion is unknown. This study investigated the correlation between the histopathologic features with demographic, gross and radiographic findings in giant cell granulomas. Materials and methods. In this analytical study, data from 23 cases of central gia...

Giant cell tumor (GCT) of bone is a giant-cell-rich bony lesion associated with abundant multinucleated osteoclast-type giant cells. It is a primary neoplasm of bone with characteristic clinical, radiological, and pathological features. It is an expansive and lytic lesion without periosteal reaction and prominent peripheral sclerosis. Giant cells are also seen in other diseases like giant cell ...
