A complication of cryotherapy and curetting
Initially it had healed with a scab; however, the scab never separated because the hairs grew back into it, making it adherent to the scalp. Under this adherent scab, pus developed, which occasionally oozed out when she pressed on the scab. Also, the pink area you see in the image above was all granulation tissue, which tends to grow excessively in this situation. All the debris was removed, as was the granulation tissue, and if it recurs it will be treated with a strong topical steroid lotion. Sometimes this is described as erosive pustular dermatosis of the scalp and may occur following both cryotherapy and curetting of scalp lesions.
