Warts - Hyperkeratotic, exophytic and dome-shaped papules or nodules
Verrucae common locations
Fingers, dorsal hand. May occur anywhere on body. Autoinoculation from scratching may cause linear pattern.
Verrucae Palmares et Plantares
Thick, endophytic papules - palms, soles, and lateral hands and feet.
Painful and resistant to therapy
Verrucae Planae
Exophilic skin colored or reddish, slightly elevated, flat-topped papules.
Most commonly on dorsal hands, arms, or face.
Verrucae Treatment
Liquid Nitrogen, topical retinoids and other topicals
Molluscum Contagiosum - what is it and what are the lesions?
Pox virus, largest virus to infect the body.
White, pink, or flesh-colored, dome shaped papules or nodules with central umbilication (not initially present)
Molluscum Contagiosum - How's it transmitted and what's the incubation period?
Direct bodily contact, fomites, and self inoculation.
14-50 days
Molluscum Contagiosum - treatment, classic sign when biopsied
No one good one.
Physical destruction, chemical destruction or topical therapy.
When biopsied, you see the classic molluscum bodies
Herpes Simplex Virus - Primary Gingivostomatitis
seen in children and young adults following primary infection of HSV-1
fever, sore throat, painful vesicles/erosions on the tongue, palate, buccal and gingival mucosa.
Erosions covered with characteristic gray membrane
Herpes Simplex Virus - Primary Genital Herpes
most cases from primary infection of HSV-2
multiple painful erosions, often bilateral, on the anogenital mucosa
painful inguinal lymphadenopathy
severity of symptoms peaks 8-10 days
Herpes Simplex Virus - Recurrent Genital Herpes
tender grouped erosions, shorter duration of symptoms, greater recurrence rate with HSV-2 than HSV-1
Herpes Simplex Virus - Recurrent Herpes Labialis
Typically affects skin-mucosa junction of mouth, clustered lesions
Herpes Simplex Virus - Herpes Gladiatorum
affects wrestlers and rugby players, commonly on face, lateral neck, medial arms
Herpes Simplex Virus - Herpes Whitlow
Intense painful infection of the hand involving 1 or more fingers. Typically affects terminal phalanx.
HSV-1 60%
HSV-2 40%
Herpes Simplex Virus - Neonatal Herpes Simplex
Usually acquired through delivery of infected vaginal canal (HSV-2).
"Dew drop on a rose petal"
Primary infection in non-immune host.
More severe with age
Varicella - incubation and contagious
Incubation period of 10-23 days
communicable 1 day prior and 6 days after.
Crusts non-infectious
Varicella in adults and teens
Usually constitutional symptoms, pulmonary involvement
Varicella viral course
Abrupt onset of descrete erythematous macules and papules over thorax, scalp, and mucous membranes
macule-> papule-> vesicle w/erythematous areola-> umbilicated vesicle-> pustule-> crusts over in 2-4 days -> crusts fall off in 1-3 wks
Varicella treatment
Herpes Zoster
lesions may be preceded by itch, tenderness, pain
neurological changes - hyperesthesia, dysthesia, hypoesthesia
From pain to eruption in 3-5 days (may be as long as 10)
Herpes Zoster - Viral course
Lesions first posterior, progress anterior
Grouped erythematous based papules, vesicles, pustules, crusts
Spontaneously gone in 1-2wks
Herpes Zoster - Nerves involved
50% thoracic
15-20% cervical or lumbar
tip of nose is nasociliary branch of opthalmic division of V
Post-Herpatic Neuralgia - Why??
Herpes Zoster - Why treat?
reduces duration of post-herpatic neuralgia
accelerates rate of lesion resolution
reduces duration of viral shedding
