Fatal disseminated Trichosporon asahii fungemia in a child with acute lymphoblastic leukemia and a morbilliform eruption

Abstract Trichosporonosis is a rare, life‐threatening, opportunistic fungal infection that affects immunocompromised individuals with neutropenia, particularly those with underlying hematologic malignancies. We present the case of a 10‐year‐old boy with acute lymphoblastic leukemia who developed a diffuse, morbilliform eruption in the setting of fever and pancytopenia. He was found to have Trichosporon asahii fungemia with widespread visceral dissemination, and his condition rapidly deteriorated despite treatment. It is important to consider trichosporonosis in the evaluation of a critically ill individual with neutropena and a rash, because the initial cutaneous presentation may appear benign and delayed therapy results in death.
