The article presents the results of pathomorphological studies of chromomycosis of the skin in 10 patients. The material from the center of the lesion focus, from its periphery and from bordering areas of the apparantly healthy skin were investigated pathomorphologically. Two variants of inflammation are described. The former was characterized by proliferation of the epiderma, the presence of polymorphocellular infiltrate and microabscesses, numerous elements of Hormodendrum. In two patients with an elevated content of sugar in the blood a tendency to the expansion of the process was noted. The second variant was of a tuberculoid character.
