Expected headings
"Associations"
"Dermoid cysts are benign. They result from inclusion of epithelial tissue within the neural groove during embryonic development. Like epidermoid cysts, they have a lining of stratified squamous epithelial cells; unlike epidermoid cysts, they also contain sebaceous glands, sweat glands and hair follicles, which account for the fat intensity signal seen in these lesions. Unlike true neoplasms which grow by progressive cell division, dermoid cysts enlarge by desquamation of normal cells and secretion of dermal elements into the cystic cavity."
