Superficial spreading (and disappearing) seborrheic keratosis.

Winkelmann RK.

Section of Dermatology, Mayo Clinic Scottsdale, Arizona, USA.

A rapidly spreading plaque of seborrheic keratosis developed following liquid nitrogen treatment and involuted quietly after a dermatitis developed; polymerase chain reaction of the tissue did not demonstrate papillomavirus DNA. Seborrheic keratoses can both develop and involute from more than one cause.
