What are the Histological Characteristics of Fungal Infections?
Fungal infections typically show chronic inflammation with the presence of macrophages, lymphocytes, and giant cells. Special stains like Gomori methenamine silver (GMS) and Periodic acid-Schiff (PAS) are used to visualize fungi in tissue sections. Fungi can appear as yeast forms, pseudohyphae, or true hyphae, depending on the species. For example, Candida species often show budding yeast forms and pseudohyphae.
