Benign Epithelial Lesions? Flashcards
most common benign epithelial neoplasm seen intraorally, HPV-associated (lower strains)
squamous pappilloma
what are the clinical signs of squamous pappilloma?
- SOLITARY lesion, often found on soft palate/uvula, or tongue
- Papillary fronds, usually pedunculated, may be sessile
what is the color or squamous papilloma?
reddish to white
what is the tx of squamous papilloma?
-conservative excision
what is the px for squamous papilloma?
- excellent
- limited grown potental, recurrences are uncommon, no risk of malignancy
-“common wart”
verruca vulgaris
what causes verruca vulgaris?
several strains of HPV
who does verruca vulgaris usually affect?
children (hands and facial skin)
-intraoral lesions uncommon
what are the clinical presentations of verruca vulgaris?
usually sessile, exophytic, papillary lesion
-often multiple
what is the tx of verruca vulgaris?
- spontaneous regression common in kids
- excision, cryotherapy, keratolytic agents
- may recur
“venereal wart”
condyloma acuminatum
how is condyloma acuminatum spread?
direct contact
where is condyloma acuminatum spread?
labial mucosa, soft palate, lingual frenum
what causes condyloma acuminatum?
several strains of HPV, including types 6 and 11 as well as high risk strains
who does condyloma acuminatum affect most?
teenagers and young adults
what is the clinical description of condyloma acuminatum?
MULTIPLE sessile papules or plaques with a cauliflower-like surface
what is the tx for condyloma acuinatum?
-excision, cryotherapy, laser ablation
is recurrence common for condyloma acuminatum?
-yes, 30% of pts
very common benign cutaneous lesion of epidermal origin that occurs at SUN EXPOSED SURFACES
seborrheic keratosis
where do you normally find seborrheic keratosis?
- sun exposed surfaces
- face, trunk, extremities (areas with numerous sebaceaous glands)[not palms or soles]
what age group is most often affected by seborrheic keratosis?
40 and over
what is the clinical presentation of seborrheic keratosis?
- sharply demarcated, slightly raised plaques
- range in color from tan, brown, to nearly black
- have a “stuck on” appearance - “dirty candle wax dripped into skin” or “mud thrown against a brick wall”
what are variations of seborrheic keratosis known as?
DERMATOSIS PAPULOSA NIGRA
who does dermatosis papulosa nigra primarily affect?
affects 35% of AAs
- autosomal dominant inheritance
- onset during adolescence
what is the clinical presentation of dermatosis papuloasa nigra
appear as small (1-2mm diameter), smooth, dark papules located on the face, particularly in the malar region
a relatively common benign process that most often occurs on the facial skin of middle aged or older adults that may be solitary or several umbilicated papules with a yellowish tinge, 1-5mm in diameter
sebacceous hyperplasia
what might sebacceous hyperplasia be mistaken for?
basal cell carcinoma
what is a helpful diagnostic aid for sebacceous hyperplasia?
pressure towards the center of the lesion often expresses sebum into the central depression
what is the tx for sebacceous hyperplasia
- none is necessary
- simple surgical excision for cosmetic purposes or to rule out basal cell carcinoma
what is the px for sebacceous hyperplasia?
excellent
diffuse white appearance to the palatal mucosa, surface may be wrinkly or fissured. elevated papules with puctated red centers (represent inflamed salivary gland orifices)
nicotine stomatosis
what is nicotine stomatosis associated with?
smoking, especially pipe or cigar
- a response to HEAT generated, rather than chemicals in the tobacco smoke
- chronic drinking of hot beverages elicits the same response
how do you dx nicotine stomatosis?
clinically
what is the treatment for nicotine stomatosis?
-none needed but pt should be encouraged to quit smoking
what is the px for nicotine stomatosis?
- excellent, not precancerous
- should resolve within 1-2 weeks of smoking cessation
