Central giant cell granuloma (CGCG) is an uncommon, benign, proliferative, and nonodontogenic lesion whose etiology is not defined. Thought to represent a reparative response to intrabony haemorrhage and inflammation, CGCG was once regarded as a reactive lesion. Central giant cell granuloma usually is an asymptomatic lesion, which may become evident during routine radiographic examination or as...

Intraosseous vascular lesions are rare conditions, comprising only 0.5 to 1% of all intraosseous hemangioma tumors. They mainly occur in the second decade of life especially in female. The most common locations are the vertebral column and skull; nevertheless, the mandible is quite rare location. Hemangiomas are benign vasoformative neoplasms of endothelial origin. However, the origin of centra...

The term odontogenic keratocyst was first used by Philipsen in the year 1956. The lesion was renamed by him as keratocystic odontogenic tumor (KCOT) and reclassified as odontogenic neoplasm in the World Health Organization's 2005 edition that occurs commonly in the jaws having a predilection for the angle and ascending ramus of mandible. In contrast, KCOTs arising in the maxillary premolar regi...

Verrucous proliferation arising from odontogenic cysts is a rare entity. We report an unusual case of an infected odontogenic cyst with verrucous proliferation and melanin pigmentation in a 13-year-old male patient who presented with an intraoral swelling in relation to impacted teeth 26 and 27. The enucleated lesion was diagnosed as an odontogenic keratocyst and the patient died within two yea...

The lesion traditionally known as odontogenic keratocyst has been renamed by WHO in 2005, as “keratocystic odontogenic tumor” as it is more appropriate and reflects its potential for local, destructive behavior. It is a benign intraosseous neoplasm of jaw, which is unusual due to its characteristic histopathological and clinical features, including potentially aggressive behavior, high recurren...

Odontogenic cysts, which showed cystic radiolucency in the jaw bone by radiographic examination and computed tomography, were enucleated by operation in 3 dogs. One dog had a odontogenic keratocyst in the incisive bone of the right maxilla and another 2 cases revealed dentigerous cysts in the mandible. These cyst walls were enucleated or transpired by semiconductor laser. Afterwards, osteogenes...

Odontogenic keratocyst (OKC) is a cyst of tooth origin with an aggressive clinical behavior including a high recurrence rate. It has been rechristened to Keratocystic odontogenic tumour (KCOT), as it better reflects its neoplastic nature. We report 2 contrasting cases of KCOT in association with impacted teeth and revisit the various treatment modalities used to tackle the aggressive nature and...
