A Comparative Analysis of p63 Expression in Giant Cell Tumour (GCT), Central Giant Cell Granuloma (CGCG) and Peripheral Giant Cell Granuloma (PGCG).

Head Neck Pathol 2019 Dec 23. Epub 2019 Dec 23.

Department of Oral & Maxillofacial Pathology, Nair Hospital Dental College, Dr. A.L. Nair Road, Mumbai Central, Mumbai, 400008, India.

Giant cell tumour (GCT) is locally aggressive benign neoplasm of long bones whereas giant cell granulomas; central giant cell granuloma (CGCG) and peripheral giant cell granuloma (PGCG); are tumour-like conditions of the oral cavity. This study aimed to evaluate and compare the immunohistochemical expression of p63 in GCT, CGCG, PGCG and determine whether p63 can be used as a diagnostic, prognostic and differential biomarker between these entities. Histopathologically diagnosed 10 cases of GCT, 20 cases of CGCG and 20 cases of PGCG were subjected to p63 immunohistochemical staining. Read More

Generalised papular variant of elastolytic giant cell granuloma.

BMJ Case Rep 2019 Dec 16;12(12). Epub 2019 Dec 16.

Department of Dermatology and Venereology, Hospital de Braga, Braga, Portugal.

Elastolytic giant cell granuloma (EGCG), also known as actinic granuloma, is an uncommon granulomatous dermatosis usually characterised by asymptomatic annular plaques on sun-exposed skin. Its aetiology is not fully elucidated, but actinic damage has been considered the main causal factor. Atypical variants with lesions in a non-photodistributed pattern are rare and often related to a systemic disorder, suggesting a more complex pathogenesis and demanding for a screening work-up.

Molecular findings in maxillofacial bone tumours and its diagnostic value.

Virchows Arch 2020 Jan 14;476(1):159-174. Epub 2019 Dec 14.

Bone Tumour Reference Centre, Institute of Pathology, University Hospital Basel, University of Basel, Basel, Switzerland.

According to the WHO, mesenchymal tumours of the maxillofacial bones are subdivided in benign and malignant maxillofacial bone and cartilage tumours, fibro-osseous and osteochondromatous lesions as well as giant cell lesions and bone cysts. The histology always needs to be evaluated considering also the clinical and radiological context which remains an important cornerstone in the classification of these lesions. Nevertheless, the diagnosis of maxillofacial bone tumours is often challenging for radiologists as well as pathologists, while an accurate diagnosis is essential for adequate clinical decision-making.

The family form of giant cell reparative granuloma or cherubism is a rare benign lesion of the jaws which causes face deformation reminiscent of the cherubs portrayed in Renaissance art. Radical surgery, especially in children before puberty, is impossible or irrational, because it leads to disablement. For four years, a child with cherubism was undergoing an outpatient supervision in the Department of Maxillofacial Surgery in Russian Children Clinical Hospital. Read More
