Supernumerary teeth (hyperdontia) can be the result of problems such as cleidocranial dysostosis and labial palatal cleft. They also can be caused by Ehlers-Danlos syndrome, Gardner's syndrome and Fabry-Anderson syndrome.
Lipomas are adipose tumors that are often located in the subcutaneous tissues of the head, neck, shoulders, and back. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. These slow-growing, nearly always benign, tumors usually present as nonpainful, round, mobile masses with a characteristic soft, doughy feel. Rarely, lipomas can be associated with syndromes such as hereditary multiple lipomatosis, adiposis dolorosa, Gardner's syndrome, and…
EPITHELIAL INCLUSION CYST Def: traumatic implantation of epidermis into dermis, plugged follicle Can be associated with Gardner's syndrome (polyposis) SSx: slow-growing, white, round, firm, usually < 1 cm DDx: neoplasm Tx: excision, marsupialization
osteoma What is the most common benign tumor of the nose and paranasal sinuses? Also associated with Gardner's Syndrome (image shows a sclerotic mass surrounded by air and located within the frontal sinus).
Single axial CT of the head without contrast shows a well defined, calcified mass within the left frontal sinus. This is the typical appearance for a Sinonasal Osteoma. Classically they are asymptomatic, and thus are incidental findings on imaging studies done for other reasons. Sinonasal osteomas are the most common benign tumor of the sinuses. They can be associated with Gardner syndrome, an autosomal dominant transmitted familial adenomatous polyposis syndrome.
