Exam 3- Lecture 1 Flashcards
abnormal increase in the NUMBER of normal cells
Hyperplasia
calcifications are a mixture of cementum and bone trabeculae, well defined RL with RO lesion. surgical excison for treatment
cemento-ossifying fibroma a
original tumor with the source for metastisis
primary tumor
cancer; resistant to treatment and causes death
malignant tumor
this is a malignant skin tumor composed of basal cells that is derived from squamous epithelium, association with sun exposure… does not occur in the oral cavity
basal cell carcinoma
what are the three types of epithelial tumors?
squamous epithelium
salivary gland epithelium
odontogenic epithelium
this appears clinically as nonhealing ulcer of the skin with a characteristic rolled borders, does not occur in oral cavity and recommend a biopsy if not healed in 10 days
basal cell carcinoma
invades and destroys surrounding tissue and has the ability to spread throughout the body… CANCER
malignant tumor
these are malignant tumors of epithelium and ten times more common than sarcomas
carcinoma
malignant tumor of salivary gland origin that can originate from either major or minor salivary gland tissue, slow growing, painful
adenoid cystic carcinoma (Cylindroma)
where does pleomorphic adenoma occur?
extraoral: parotid gland
intraoral: palate
malignant tumors of salivary glands
adenocarcinoma
who does SCC occur in?
majority of older patients in their fortys
malignant tumor of epithelium
carcinoma
who does florid osseous dysplasia occur in, treated and what is a complication?
older black women… no treatment
osteomyelitis in patients wearing C/C or RPD/RPD
malignant tumor of CT
sarcoma
this is AKA Pindborg Tumor… benign epithelial odontogenic tumor that occurs less frequently than an amelobastoma.. composed of islands and sheets of polyhedral cells
calcifying epithelial odontogenic tumor (CEOT)
what does an amelobastic fibroma look like on a radiograph and how is it treated?
well defined or poorly defined uni or multiocular RL
surgical removal
who and where does amelobastic fibroma occur in?
young children less than 20 years in the mand PM molar region
type of monomoprhic adenoma with two tissue types (epithelial and lympoid), presents as painless, soft fluctuating mass of parotid gland… bilateral and treat with surgical excision
warthins tumor (adenolymphoma)
How do you treat a benign tumor?
surgical excision
a malignant tumor of squamous epithelium, most common malignancy of oral cavity and it can metastasize to distant sites.. usually an exophytic ulcerative mass
squamous cell carcinoma
likely to cause the death of the host
malignant
where and who does benign cementoblastoma occur in?
young adults in the mand. molar or PM area. pain is a frequent symptom and removal of lesion or tooth for treatment
not malignant, favorable for recovery
benign
malignant tumors of CT
sarcoma
study of tumors or neoplasms
oncology
what is the 5 year survival rate for mucoepidermoid carcinoma?
low grade: 92%
high grade: 49%
where are the most common sites of SCC?
floor of the mouth, lateral borders of tongue, soft palate, tonsillar pillar, and retromolar areas
means new growth in which cells exhibit uncontrolled proliferation
neoplasia
this is a benign encapsulated salivary gland tumor that are much rarer than pleomorphic adenomas, occurs in adults in upper lip and treat with surgical excision
monomorphic adenoma
tooth forming
odontogenic
increase in quantities
proliferation
common condition of unknown cause that affects periapical bone, not a premalignant condition.. asymptomatic found on routine PA x-ray
periapical cemental dysplasia
What are some characteristics of papilloma?
cauliflower appearance, occur at any age, found in soft palate and treat with surgical excision
occurring within the bone
central
