Final Revision Flashcards
How is Squamous Papilloma caused:
HPV 6 and 11 infection
From which other disease is difficult to distinguish Squamous Papilloma from?
verruca vulgaris, condyloma acuminatum, verruciform xanthoma, or multifocal epithelial hyperplasia
Verruca Vulgaris (Common Wart):
caused by:
most often in which people:
- HPV 2
- Is contagious and can spread to other parts of a person’s skin or mucosa
- Most often arises in children
SOS
Condyloma Acuminatum (Veneral Wart):
=
caused by:
how is transmitted?
which people?
=is an HPV virus of stratisfied squamous epithelium
- HPV 6 and 11
- sexually transmitted disease
- anogenital region, mouth, and larynx
- anogenital condylomata infected with HPV 16 or 18
- Is usually seen in immunocompromised patients
SOS
Histopathologic Features of Condyloma Acuminatum (Veneral Wart):
- multiple pieces of soft tissue composed of papillary surface epithelium with an underlying fibrous CT core
- the spinous layer has cells with empty looking cytoplasm and small nuclei consistent with koilocytes
Keratoacanthoma is caused by:
sun damage, tar exposure, HPV, immunosuppression, certain drugs, tattooing, and burns or trauma
Inflammatory Papillary Hyperplasia:
=
caused by?
- reactive tissue growth
- in maxilla
Due to:
• Ill-fitting denture
• Poor denture hygiene
• Wearing the denture 24 hours a day
Inflammatory Papillary Hyperplasia - Clinical Features:
where does it occur?
symptomatic or not
- early lesions may involve only the PALATAL VAULT, although advanced cases cover most of the palate
- asymptomatic
Verruciform Xanthoma probably represents an:
unusual reaction or immune response to localized epithelial trauma or damage
Clinical Features of Verruciform Xanthoma:
- on the gingiva and alveolar mucosa
- well-demarcated lesion
SOS
What is the most common benign salivary neoplasm?
a. mucocele
b. ranula
c. warhin’s tumor
d. none of the above
d. none of the above
answer: pleomorphic adenoma
SOS
What is the most common malignant neoplasm?
mucoepidermoid carcinoma
SOS
What is the most common side for major salivary gland tumors? (in general)
parotid
SOS
What is the most common intraoral side for minor salivary gland tumor?
palate
SOS
Bilateral parotid glands are most likely in what type of benign tumors?
warthin tumors
SOS
Older females and salivary gland in upper lip most likely will be?
What benign neoplasm is most likely to appear in the upper lip?
canalicular adenoma
- is most often in OLDER females
- may also be a basal cell adenoma
SOS
Association pain due to perineural invasion what is the first malignant neoplasm that comes in mind?
adenoid cystic carcinoma (ACC)
SOS
If the tumor is ulcerated or is in palate/parotid gland and we have facial nerve paralysis or weakness this tumor is always: benign or malignant?
Malignant until proven otherwise
SOS
What is the most common malignancy in children? (salivary gland)
Where?
mucoepidermoid carcinoma
-in parotid gland most common
SOS
Which malignant salivary neoplasm is almost exclusively a tumor of the minor salivary glands?
/ Minor salivary gland, only seen on palate, painless, or can erode the underlying bone - we are talking about:
Polymorphous low grade adenocarcinoma (plga)
-exclusively on minor salivary gland
SOS
Differential diagnosis depends/based on:
the SITE of the tumor and the clinical FEATURES
SOS
If there is a tumor in the palate and overlying mucosa is ulcerated and the ulceration is not related to trauma or biopsy the mass is malignant or benign?
malignant until proven otherwise
SOS
If there is a tumor in the parotid gland WITHOUT any facial nerve paralysis or weakness the first in mind will be:
If there is a tumor in the parotid gland WITH facial nerve paralysis or weakness the first in mind will be:
Which malignant tumor is not in parotid gland:
benign neoplasms (ex: pleomorphic adenoma, warthin tumor or basal cell adenoma) and secondly: malignant tumor such as neuroepidermoid carcinoma low graded
mucoepidermoid carcinoma high graded (1st) b/c of its propercity to appear in parotid gland and (2ndly) carcinoma ex pleomorphic adenoma, acinic cell carcinoma, MASC of coarse
polymorphous low grade adenocarcinoma
SOS
If the tumor appears in the upper lip you can have in mind which types of tumors?
canalicular adenoma basal cell adenoma (can occur in upper lip but most commonly in parotid gland) plga acinic cell carcinoma MASC
=>pleomorphic adenoma(uncommon in upper lip)
