Radiation therapy of keratoacanthoma.
We report the radiation therapy of keratoacanthoma in 13 patients using orthovoltage X rays and electrons. All patients had an excellent cosmetic result, and time to regression was dose dependent up to a dose corresponding to TDF 50; increasing dose beyond this level did not accelerate time to regression past 2.4 months. We also note a heretofore undocumented association between keratoacanthoma and second malignancy.
