The histopathologic specimen demonstrated neovascularization with prominent small blood vessels in the papillary dermis and dermal fibrosis, consistent with a diagnosis of stasis dermatitis. Hemosiderin, demonstrated by Perls stain, was conspicuously present throughout the dermis, while increased melanin deposition in the basal layer was demonstrated by Fontana-Masson silver stain. As clinically suspected, hemosiderin deposition was considerably increased in tissue from the patient's left leg compared with the right.
