title: [Minimycetomas caused by N. brasiliensis. Histological study of 13 cases].
abstract: We present a preliminary communication of the histological findings in 16 cases of mini-mycetoma by N. brasiliensis. We found little PAS positive granules, fully evident with the Gram stain, localized at the center of the microabscesses. Ten cases showed Russell bodies, 33% showed multinucleated giant cells and the 50%, epithelioid cells. All cases showed abundant capillary vessels and intense fibrosis.
