Seborrheic Keratosis

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.


Cryotherapy or Liquid Nitrogen therapy freezes the SKs. Repeat treatment may be necessary at two-week intervals.

Curettage and Electrodesiccation: the growth is peeled away with a curette and the heat produced by an electrocautery needle destroys the SK and controls bleeding.
