  • Title: [Cutaneous alternariosis. Clinical diagnosis and therapeutic options].

    Abstract:
    Localized skin infections caused by the pigmented fungi of the genus Alternaria are being increasingly observed. In the past, primarily patients receiving long-term glucocorticoid therapy were likely to have this mycosis, which is commonly traumatic, but now it is frequently encountered in organ transplantation patients. Possible therapeutic options and differential diagnosis are discussed by means of two case reports--a female renal transplant patient infected by A. alternata and a patient with iatrogenic Cushing syndrome infected by A. infectoria. Histopathological differentiation from other fungal infections may be difficult but is of therapeutic and prognostic significance. Finding short hyphae in tissue sections is an important clue. Since A. infectoria shows little conidial growth in culture, rDNA ITS sequencing offers another diagnostic possibility. Therapy has not yet been standardized. Along with surgical intervention, systemic itraconazole is the usual choice.
