MYCOTIC PARONYCHIA AND DERMATITIS

Abstract

Up to the time of Gilchrist's¹description of blastomycosis, comparatively little was known regarding the possible etiologic rôle played by the blastomycete and smilar organisms in the production of dermatomycoses. With the way for such investigations thus opened, many etiologic questions concerning formerly obscure dermatoses have since been settled, and the pathogenesis of this group of organisms has assumed an increasing importance. A few years after the publication of Gilchrist's report, Schenk²described the clinical picture of the disease now known as sporotrichosis; and coincidentally appeared the consecutive studies of Ophüls,³Montgomery, Ryfkogel and Morrow,⁴and others, properly identifying granuloma coccidioides with this group of diseases. In addition to the foregoing, more recent investigations have revealed the etiologic rôle of organisms biologically related to the foregoing in the production of more superficial cutaneous manifestations. Among the early writings on this type of invasion are to be
