A semiquantitative scale was devised to assess the degree of colonization of the epithelium by fungal hyphae. In this scale the absence of colonization was given a score of 0, while maximal colonization, where in excess of 50 hyphae could be seen in each high-powered field (magnification, ×400), was assigned a score of 4. The other scores were 1 for 1 to 5 hyphae, 2 for 6 to 15 hyphae, and 3 for 16 to 50 hyphae.
