Atrophoderma of pasini and pierini on the head and trunk of a 32 year-old male: A case report

@#Atrophoderma of Pasini and Pierini (APP) is an idiopathic disorder of dermal atrophy, presenting as round or oval depressed lesions most commonly observed on the trunk and extremities. Herein, we report the first case of APP initially appearing on the head. Histopathologic examination of lesional skin demonstrated a decrease in elastic fibers. Serologic tests for Borrelia and antinuclear antibody titers were negative. There was no noted improvement after 6 weeks tretament with Hydroxycholoroquine 200 mg/tab BID. Definitive disease etiology and treatment of APP remains to be elucidated.
