[Punctate maculae on the back of the hands of a 44-year-old woman].

A 44-year-old woman developed punctate erythematous maculae on the backs of her hands, arms and shoulders following a pregnancy. Laboratory evaluation was unremarkable. Our differential diagnosis includes idiopathic teleangiectases, teleangiectasia eruptiva perstans, angioma serpiginosum and angiokeratoma corporis diffusum Fabry. Microscopic examination showed increased numbers of the small vessels of the upper vascular plexus with dilated capillaries. This coupled with the clinical findings led us to the diagnosis of angioma serpiginosum with symmetrical distribution involving the shoulder girdle, upper aspects of the arms, and the backs of the hands. We treated with a pulsed dye laser and noted some regression after two sessions.
