Schamberg's disease is a progressive pigmentary dermatosis of chronic course. The present article describes the use of thioglycolic acid peelings in Schamberg's disease, with histological and photographic analyses. A 43-year-old female patient with clinical and histological diagnoses of Schamberg's disease underwent five sessions of 10% thioglycolic acid peeling in gel with an interval of 15 days between each session. The patient had considerable whitening of the lesions, with clinical improvement of 68.7%. Thioglycolic acid solubilizes the haemosiderin, being a treatment option that leads to the whitening of the lesions with good tolerance and few side effects.

Actinic purpura is characterized by dark purple patches, mainly on photoexposed areas of the extensor surfaces of the arms and hands of elderly individuals. Thus far, there is no satisfactory treatment. We report the case of an 80-year-old patient who underwent treatment with two sessions of calcium hydroxyapatite filler application in the forearms, with good results.
