Progressive pigmentary purpura related to raloxifene.

Progressive pigmentary purpura is a rare condition characterized by lymphocytic capillaritis histologically causing various clinical entities which are also named as persistent pigmented purpuric dermatoses. It is generally idiopathic; however, rare cases secondary to drugs and various diseases have been reported. In this report we describe a case of progressive pigmentary purpura induced by raloxifene, a selective estrogen receptor modulator which is primarily used in the treatment and prevention of postmenopausal osteoporosis. As far as we know, no case of progressive pigmentary purpura has previously been reported as an adverse effect of raloxifene.
