Verrucous Lesions Flashcards
Most common of the benign epithelial tumors
Common in advancing age: Onset approximately 35 years and progresses (Onset rarely before 30 years old)
Slightly more common and more extensive in males
Genetic predisposition
Isolated lesion or generalized - evolve over months to years
Face, trunk, and upper extremities most common
Seborrheic Keratosis
What are some treatment options for seborrheic keratosis?
Note: None is required
Light electrocautery then cauterized
Curettage after light freezing with cryospray (best)
Punch biopsy may be indicated
Flat excision
Single or multiple, discrete, dry, rough, adherent scaly lesions that occur on the habitually sun-exposed skin (Screen for outdoor workers and outdoor sportspersons)
Also can be from radiation or chemical exposures
Age of onset- middle age
Considered precancerous – can lead to squamous cell carcinoma
More common in males
Duration of months to years
Actinic (Solar) Keratosis
What is the pathogenesis of actinic (solar) keratosis?
Prolonged and repeated solar exposure in susceptible persons leads
to cumulative damage to keratinocytes
Single lesions (cutaneous horns) or large patches/plaques
“sun exposed areas”
Adherent hyperkeratic scale, which is removed with difficulty and pain
(crusted, ulcerated)
Can be skin colored, yellow-brown, or brown
Often there is a reddish tinge
Rough, like coarse sandpaper: “better felt than seen” – palpation is essential to diagnosis
Actinic (Solar) Keratosis
Why do we want to accurate diagnose and treat actinic (solar) keratosis?
Considered precancerous - want to remove/biopsy to rule out SCC
What are the treatment options for actinic (solar) keratosis?
May disappear spontaneously, but general remain for years
Medications:
5-Fluorouracil cream
Imiquimod
Facial peels: Trichloroacetic acid (5-10%)
Surgical procedures: Cryosurgery, Laser surgery
