WebPhaeohyphomycosis can be diagnosed by microscopic examination of exudate and biopsy specimens, which reveals pigmented, dark-walled, irregularly septate filamentous hyphae (2–6 μm in diameter) or yeast-like cells. Infected tissues may be grossly pigmented, giving an appearance of melanoma. WebDefinition. Phaeohyphomycosis consists of a group of mycotic infections characterized by the presence of dematiaceous (dark-walled) septate hyphae and sometimes yeast or a combination of both in tissue. The hyphae may be short to elongate, distorted or swollen (toruloid hyphae), regularly shaped, or any combination of the above.

"A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meanin… " - Dark walled septate hyphae
