In studies on the isolation of fungi from the skin and scalp normal-looking skin was mycologically cultured by the cotton swab method or the finger-press method, and the scalp was cultured by the hairbrush method. Patients on oral steroids and with cutaneous- or muco-candidosis, blood disease, internal disease (diabetes mellitus, malignancy, collagen disease), or cutaneous infectious disease were compared with healthy controls. Candida albicans was isolated from the skin of 15 of 26 patients (57.7%) with cutaneous- or muco-candidosis, but was not detected on 28 healthy controls; it was also isolated from 2 of 19 patients with blood disease. The rate of detection of other fungi (Aspergillus spp., Penicillium spp., black yeasts, other molds, and other yeasts) from the skin and scalps of patients with blood disease was mach lower than those of other patients and controls. Most fungi except C. albicans were more frequently isolated from the scalp than the skin. Therefore, it can be concluded that the focus of fungi colonized on the skin was the scalp; since patients with blood disease had little or no hair due to their chemotherapy, few fungi adhered their scalp, accounting for the much lower detection rate.
