Circumscribed lenticular anetoderma in an HIV-infected man with a history of syphilis and lichen planus.
Anetoderma is an uncommon dermatosis that manifests as discrete foci of well-circumscribed, atrophic skin. The condition can be idiopathic or can be secondary to a number of associated cutaneous diseases. Whereas the pathophysiologic mechanisms remain unknown, anetoderma results from diminished elastic fibers in the dermis. We present an unusual case of localized, lenticular anetoderma in a man with HIV, a history of syphilis, and lichen planus. Both of these infections have been associated with anetoderma. Although his lesions are vaguely reminiscent of a variant of syphilitic anetoderma described in the 1930s, they are confined to a smaller anatomic distribution, differ in size, and have a papular appearance. As anetoderma can develop in the context of infectious disease, a diagnosis of anetoderma should trigger a thorough examination and evaluation for treatable concomitant illnesses.
