CONGENITAL EPULIS
This is a rare lesion that occurs in neonates. It normally presents in the anterior
maxilla. It consists of granular cells covered by epithelium and is thought to be
reactive in nature. This is a benign lesion and simple excision is curative.
MELANOTIC NEUROECTODERMAL TUMOUR
This rare tumour occurs in the early months of life, usually in the maxilla. The lesion
consists of epithelial cells containing melanin with a fibrous stroma. Some localized
bone expansion may occur. The condition is benign and simple excision is curative.
SQUAMOUS-CELL PAPILLOMA
This is a benign condition that occurs in children. The small cauliflower-like growths,
which vary in colour from pink to white (1017HFig. 15.10), are usually solitary lesions.
They may be due to the human papillomavirus.
VERRUCA VULGARIS
This condition also known as the common wart may present as solitary or multiple
intraoral lesions. These may be associated with skin warts. They are probably caused
by the human papillomavirus.
FOCAL EPITHELIAL HYPERPLASIA
This is a rare condition also known as Heck's disease. It is associated with human
papillomavirus. It presents as multiple small elevations of the oral mucosa especially
in the lower lip.
