Two uncommon cases of idiopathic atrophoderma of pasini and pierini: multiple and giant.

We report a 39-year-old Chinese man presenting with approximately 200 atrophic brownish patches for 10 years, whose clinical manifestation and pathological features were consistent with the findings of idiopathic atrophoderma of Pasini and Pierini. Another described case was a 62-year-old woman who had a gradually increasing asymptomatic hyperpigmented and depressed patch on her right lumbosacral region over a period of 7 years. At the time of consultation, the size of the lesion was approximately 27 x 23 cm.
