[Importance of Perls stain in histologic diagnosis of Kaposi sarcoma].
The authors studied 27 cases of Kaposi's sarcoma, 23 cases of pyogenic granuloma, 18 cases of hemangioma, 17 cases of stasis dermatitis and 9 cases of dermatofibroma. In all these cases, they used the hematoxylin-eosin stain and Perls' stain', and they showed the presence of hemosiderin in all the cases of Kaposi's sarcoma and stasis dermatitis. The hemangioma and the dermatofibroma presented 50% of positivity, and the pyogenic granuloma, only 26.1%.
