[History of a cutaneous lesion: chromomycosis].
A modern approach of Pathology, using immunohistochemistry, electron microscopy and image analysis, was made to describe the matrix profile of the non reversible fibrosis observed in the cutaneous lesion of Chromomycosis. The distribution pattern of cell populations in dense inflammatory infiltrate, sometimes organized in granulomas, has been identified concurrently with the in situ demonstration of the pro-fibrotic cytokine TGF-beta. The professional phagocytes (polymorphonuclear neutrophils and macrophages) seem unable to fully eliminate the fungi. We suppose it is this persistence which explains the exuberant cell immune response.
