[Giant cell lesions of oral cavity].

Diagnosis of many lesions of the oral cavity is challenging to most clinicians because of their uncommon prevalence. A number of cystic, metabolic, osteodystrophic, microbial, tumour and tumour like lesions of the oral cavity present with characteristic giant cell lesions; which makes their diagnosis and study simpler. We have attempted to classify the common giant cell lesions of the oral cavity, giving a brief account of their clinical, histological and diagnostic features, along with their recent treatment modalities.
