Pathology Flashcards
Herpes simplex virus (HSVs) infections are commonly causing …. eruptions of the skin and mucosa.
vesicular
HSV occur in two forms …..
primary (systemic) and secondary/recurrent (localized)
Primary form of HSV
Primary Herpes Gingivostomatitis (primary herpes)
Primary herpes is most frequently seen in …..
children(1 to 5 years)
Clinical presentation of primary Herpes in mucosa
numerous pinhead vesicles, which rapidly collapse to form numerous small, red ulcers.
Adjacent ulcerations may coalesce to form larger, shallow, irregular ulcers.
Clinical presentation of primary Herpes in gingiva
the gingiva is enlarged, painful, and extremely erythematous.
Ulcers along midfacial free gingival margins (not involving to interproximal papillae)
3 types of recurrent HSV
Herpes labialis
Intraoral Herpes
Herpetic Whistlow

(occurred in dental practitioners without glove)
The most common site of herpes labialis is
vermilion border and adjacent skin of the lips
Prodromal signs and symptoms of herpes labialis
pain, burning, itching, tingling, localized warmth, and erythema of the involved epithelium
Clinical presentation of herpes labialis
clusters of fluid-filled vesicles containing virus. The vesicles rupture and crust within 2 days.
Apthous Ulcerations: which mucosa
Non-keratinized
CENTRAL GIANT CELL GRANULOMA
- benign or malignant?
- giant cell ?
