Background And Objectives:
Giant cell lesions (GCLs) are rare lesions which prominently feature multinucleated giant cells in their histology. They include central giant cell granuloma (CGCG), giant cell tumour of bone (GCT), peripheral giant cell granuloma (PGCG), Cherubism (CHB), e.t.c. This study reviewed the clinico-demographic parameters of GCLs of the jaws and assessed the giant cells.
Methods:
This was a retrospective study examining the histopathology records of which part of the body of two tertiary institutions. All entries of cases diagnosed as GCLs were retrieved and data were extracted. Also, the giant cells in tissue sections were assessed. Data were analysed using SPSS Inc. version 20 while Chi square test was used to test for association. This was considered significant quand p < 0.05.
Results:
Over the study period, 2,862 biopsy reports were reviewed. GCLs constituted 48(1.7%) and M: F ratio was 1:1.6 while majority occurred in the 2nd and 3rd decades. The mandible was the most common site recording 27(56.3%) cases and CGCG was the most frequently diagnosed GCL constituting 22(45.8%). Assessment of the giant cells revealed CGCG had predominantly large giant cells, a dense dispersal of giant cells and irregularly shaped giant cells, while CHB mainly had large giant cells with dense dispersal, but round shaped giant cells.
Conclusion:
GCLs are rare lesions commonly seen in females in the 2nd and 3rd decades of life with preference for the mandible. CGCG was the most commonly encountered lesion, while the giant cells in CGCG and CHB were similar in size as well as dispersal.
