Skin and breast disease in the differential diagnosis of chest pain

A cause of unbearably painful breast, diffuse dermal angiomatosis

Diffuse dermal angiomatosis is a rare disorder, considered to be a variant of reactive cutaneous angioendotheliomatosis. The patients commonly present with severe intractable breast pain and characteristic reticular violaceous erythematous plaques with central ulcerations. Histologically, there is infiltration of the recticular dermis by endothelial cells due to excess vascular proliferation. Herein, we report a patient who presented with unbearable bilateral breast pain with characteristic "reticular vascular marking" of her breasts, who was diagnosed with diffuse dermal angiomatosis. We were able to successfully treat our patient with a tapered isoretinoin regimen.
