Seborrheic Keratosis

Picture of seborrheic keratosis
Causes:
Exact cause is unknown

Condition Overview:
Seborrheic keratoses are non-cancerous growths of the outer skin layer. SKs occur singly or in a cluster and are usually brown in color, SKs can vary from tan to black.  SKs have a waxy, almost pasted-on look. Almost every adult will eventually develop at least of few of these growths as they are more common with aging.

Treatments:
  • Cryotherapy or Liquid Nitrogen therapy freezes the SKs. Repeat treatment may be necessary at two week intervals.
  • Curettage and Electrodessication: the growth is peeled away with a curette and the heat produced by an electrocautery needle destroys the SK and controls bleeding.
