Emerging Cutaneous Phaeohyphomycosis Caused by Alternaria infectoria

Alternaria species belong to a group of opportunistic fungi that causes skin infection mainly in immunosuppressed patients. The authors describe two clinically distinct cases of cutaneous alternariosis caused by Alternaria infectoria in patients under prolonged corticosteroid treatment. Additionally, a brief review of published cases in portuguese patients is conducted.

Typical Skin

Serratia marcescens is an uncommon gram-negative bacterium strain that does not cause skin infections in healthy individuals. However, it is rarely reported as the causative agent of infection in immunosuppressed patients or in nosocomial infections. A 51-year-old man was admitted to a hospital presenting with pus and pain that had developed a month ago on a hypertrophic scar area of the back. Although he was on medication for diabetes mellitus, his blood sugar level was poorly controlled. In addition, two months earlier, he received an intralesional injection of 40 mg/mL triamcinolone twice for the hypertrophic scar of the back. S. marcescens was identified in the wound culture. His condition improved after ceftriaxone administration, debridement, and split-thickness skin grafts. Although S. marcescens is an infrequent cause of skin infections, it is important to remember that it may cause infection in some patients and that the course of the disease may be worse than that in a typical skin infection with poor prognosis.
