Mucormycosis has recently emerged as a concern with the increasing prevalence of immunocompromised states, including acquired immunodeficiency syndrome and post–organ transplantation. The causative organisms are ubiquitous fungi belonging to the class Zygomyces and the order Mucorales (Rhizopus, Mucor, or Absidia). Data do suggest that the Rhizopus species accounts for the majority of mucormycosis cases in humans.1 However, the diseases manifested by the Mucorales order of organisms are largely indistinguishable. Although these air-borne pathogens are commonly isolated from environmental sources, they rarely produce infections in the presence of normal systemic resistance.
