Microscopic examination revealed the presence of acanthosis and interdigitation of elongated rete ridges with extended connective tissue papillae. A dense chronic inflammatory infiltrate was present in the dermis. There was exocytosis of polymorphonuclear cells into the epithelium, with the formation of microabscesses (Figure 2). A periodic acid–Schiff stain showed several intraepithelial yeast forms with pseudohyphae corresponding to Candida albicans (Figure 3).
