Coexisting fungal infections were found in 438 pat.ient,s(25.5% ), and the cases of Tinea manus wit.h Tinea pedis was the most common. 7. In dermatophytosis, a positive rate for the KOH mount examination was 52.4%, and a positive rate of culture on ordinary Saborauds dextrose agar media was 41.4%. 8.
