Keratocystic odontogenic tumour

Keratocystic odontogenic tumour (KCOT) is a benign neoplasm that originates from the dental lamina. It is a unique entity due to its aggressive behaviour, high recurrence rate and characteristic histological appearance.

Clinical Features

KCOTs are often asymptomatic and are usually discovered during routine radiographic examinations. However, they can present with symptoms such as pain, swelling, infection, and displacement of teeth.

Diagnosis

The diagnosis of KCOT is based on a combination of clinical, radiographic, and histopathological findings. Radiographically, KCOTs typically appear as well-defined radiolucent lesions with smooth and often corticated borders. Histologically, they are characterized by a thin, uniform epithelial lining with a corrugated parakeratin surface and a prominent basal cell layer.

Treatment

The treatment of KCOTs is controversial due to their high recurrence rate. Treatment options include conservative approaches such as enucleation and curettage, and more aggressive approaches such as resection.

Prognosis

The prognosis of KCOTs is generally good, but they have a high recurrence rate, especially if not completely removed.
