[Histopathological diagnosis of mycoses in veterinary pathology].
Histopathological analysis demonstrates the morphology of the fungi and shows their relationship with tissue lesions, which is a valuable information in the diagnosis of veterinary mycoses, especially in superficial infections where reservoirs make difficult the diagnosis using other techniques. On the other hand, histopathological analysis should be complementary to other methods such as culture, immunohistochemistry, serology, PCR, etc. In this work, the most relevant histopathological features of some of the most common mycoses of domestic animals, some of which have zoonotic potential, are described and their differential diagnosis is discussed. To facilitate the discussion of the differential diagnoses, mycoses have been grouped by the sites of the infections and by the nature of the fungi (dimorphic and filamentous). Mycoses included in the study were 1) Superficial and deep infections: dermatophytosis, dermatophytic pseudomycetoma, eumycotic mycetoma, phaeohyphomycosis and malasezziasis. 2) Systemic mycoses: aspergillosis and zygomycosis. 3) Mycoses due to dimorphic fungi: candidiasis, cryptococcosis, blastomycosis, sporotrichosis, coccidioidomycosis and histoplasmosis. 4) Infections by algae and other fungi: protothecosis and pneumocystosis.
