That emphasizes the importance of early and accurate diagnosis despite the confounding clinical and histopathological aspects. Keys of diagnosis are the high level of susceptibility and patient’s multidisciplinary approach.

4. Protocols of British Society for Medical Mycology The pathologist is not called to establish the exact type of fungi, the pathological report must include: the presence and absence of yeast forms, the presence and absence of hyphae, whether hyphae are septate or aseptate, presence of melanin, the size of fungi, cellular location any specialised structures Applying these standards in routine examination of inflammatory skin biopsies micotic infection can be identified as cause of inflammation, thus improving management of immunocompromised patients. The appearance of fungi can be sufficient to guide treatment, but the golden standard requires either immunohistochemical confirmation of the specific type or confirmatory cultures. Patients with poor immune status have, usually, a long, difficult evolution, with possible fatal outcome due to systemic dissemination of fungal infection. Bronchopneumonia (case 2) HE
