ABSTRACTUsing electron microscopic methods, we observed the fine structure of fungal elements occurring in a facial granulomatous infection caused byTrichosporon cutaneum.Two types of fungal elements were recognized: (1) fungal elements attached to phagocytes or just ingested into phagocytes and (2) fungal elements located within the phagocytes in the process of being digested.All the fungal elements observed had been denatured to varying degrees. In these denatured fungal elements, the intracellular organelles had disappeared. Fibrillar structures derived from the cell wall were recognized.
