Majocchi's granuloma is a folliculitis caused by dermatophytes, which is most commonly located on the skin of the lower limbs in women. A favorable factor for the infection is an injury caused by epilation, which, together with an existing fungal infection, can lead to the spread of folliculitis to other parts of the body. The disease is extremely rare (Burgdorf et al., 2010). The aim of this article is to describe the case of a patient who developed severe edematous lesions of the lower extremities from a mycosis infection with Trichophyton mentagrophytes varietas granulosum, the carrier of which was a domestic guinea pig...

The patients with hematologic malignancies and hematopoietic stem cell transplantation (HSCT) recipients are at high risk for invasive fungal diseases (IFDs) mainly due to the severe and prolonged neutropenia related to high-dose chemotherapy. Voriconazole prophylaxis is recommended for possible IFDs. Mucormycosis is a fulminant infection, which may occur after voriconazole prophylaxis for invasive aspergillosis in immunocompromised hosts. Here, we report mucormycosis after 4 months of voriconazole prophylaxis in a young patient with relapsed acute lymphoblastic leukemia and hematopoietic stem cell transplant failure and discuss the clinical manifestation, imaging, laboratory findings and therapeutic regimens...

I Hadrich, A Ayadi
Fungal infections are a major cause of morbidity and mortality despite the latest developments of diagnostic tools and therapeutic options. Early initiation of the appropriate antifungal therapy has been demonstrated to have a direct impact on the patient's outcome. Antifungal susceptibility testing methods are available to detect antifungal resistance and to determine the best treatment for a specific fungus. American and European standards have been developed, as well as equivalent commercial systems, which are more appropriate for clinical laboratories...
