Cutaneous alternaria infection in a patient on chronic corticosteroids

We have presented a case of invasive cutaneous alternariosis in a patient receiving chronic oral steroid therapy. Alternaria must be considered in the differential diagnosis of any progressive cutaneous infection in an immunocompromised patient. Invasive maneuvers are often needed to confirm the diagnosis. Given the rarity of cases and lack of controlled clinical trials, firm therapeutic guidelines are not available. Clinicians are likely to encounter more such cases as the population of immunocompromised hosts grows.
