Fusarium species are saprophytic fungi that may colonize human skin and nails and may rarely cause invasive infections in traumatized tissue and in debilitated and immunocompromised patients. We report herein a case of invasive intranasal Fusarium oxysporum infection in a diabetic patient. This unusual presentation potentially can be confused with early rhinocerebral zygomycosis clinically and histologically. Distinguishing morphologic features and the possible role of diabetes in promoting this infection are discussed.

Zygomycosis often occurs in patients with an underlying disease, e.g., diabetes mellitus, leukemia, and lymphoma, or an immunocompromised state. This report discusses a case of a 21-year-old woman with systemic lupus erythematosus complicated by uremia, acidosis, steroid therapy, prolonged antimicrobial therapy, and disseminated zygomycosis.

A 63-year-old diabetic man presented with sinusitis with orbital and intracranial signs progressing over one week, due to zygomycosis. Despite control of the diabetes, surgical excision of infected tissue and antifungal therapy he died in the fifth week of illness. Pathological study showed extensive fungal infiltration of periorbital structures and mycotic thrombosis of many blood vessels with associated necrosis and infarction of fat and extraocular muscles.

Mucormycosis is an often-fatal opportunistic fungal infection caused by members of the class Zygomycetes (Phycomycetes), order Mucorales. Most cases are diagnosed by histologic examination, through the identification of mucormycotic hyphae in infected tissues. Chronic debilitating conditions accompanied by acidosis such as diabetes mellitus, as well as leukemia, lymphoma, and immunodeficient states, predispose to the development of this type of opportunistic infection. This report describes a hitherto undescribed finding, the presence of structures consistent with sporangia in tissue sections, in a case of pulmonary mucormycosis occurring in a nondiabetic patient with metabolic acidosis secondary to chronic salicylate poisoning.

A large variety of underlying conditions and diseases have been associated with zygomycosis. The most common ones include leukemia or lymphoma, burns, renal failure, septicemia, malnutrition, diabetes, cancer, chemotherapy, organ transplantation, and corticosteroid administration. While being ubiquitous in the environment and relatively harmless to healthy individuals, Zygomycetes can be fatal in the immunocompromised patient, especially if untreated or if treatment is delayed.

We investigated the potential of 33 different zygomycete isolates to cause cerebral disease following the intranasal instillation of their spores into ketotic rabbits with alloxan induced diabetes. The isolates represented six thermotolerant species of Rhizopus (R. arrhizus, R. chinensis, R. microsporus, R. oligosporus, R. oryzae, and R. rhizopodiformis), Absidia corymbifera, Cunninghamella bertholletiae, and Rhizomucor pusillus. All 13 isolates of the thermotolerant Rhizopus species proved to be cerebral pathogens as confirmed by culture and histopathology. One isolate of R. oligosporus and one isolate of R. rhizopodiformis, however, were less pathogenic than isolates of other Rhizopus species tested. Cerebral pathogenicity was noted with 2 of 5 isolates of Rh. pusillus and only 1 of 13 A. corymbifera isolates. Two thermotolerant C. bertholletiae cultures, recovered from human lesions, did not cause either cerebral or pulmonary disease in ketotic rabbits. The incidence of pulmonary zygomycosis caused by the isolates of the species of the four genera under study was as follows: Rhizomucor 24%, Rhizopus 22%, Absidia 9%, and Cunninghamella 0%. This study confirms the pathogenic potential of the thermotolerant species of Rhizopus to cause cerebral zygomycosis in ketotic diabetic rabbits and also revealed the potential of Rh. pusillus and A. corymbifera occasionally to cause the same disease in animals and humans.

Zygomycosis is an uncommon, but frequently fatal, fungal infection caused by members of the class Zygomycetes. The risk factors include diabetes mellitus, uremia, leukemia and use of deferoxamine as an iron-chelating agent; healthy persons also are occasionally infected. Those fungi, spread by their ubiquitous spores, most frequently involve the respiratory system. Rhinocerebral zygomycosis occurs predominantly in patients with uncontrolled diabetic ketoacidosis. Pulmonary zygomycosis most frequently is observed in granulocytopenic and corticosteroid-treated patients. Other clinical manifestations are gastrointestinal, cutaneous, disseminated and miscellaneous. This report concerns a previously robust farmer who suffered from left upper lung abscess caused by Rhizopus spp.-one member of the order Mucorales. Initially, it was intended to administer amphotericin B to a total dose of 2,000 mg; however, the patient could not tolerate such side effects as nausea, vomiting and refused further management when the cumulative dose was 948 mg. However, he did recover without further fever and cough. Chest X-ray, followed every three months, disclosed satisfactory improvement.

Zygomycosis is a rare but highly invasive fungal infection that occurs in transplant recipients. We report a case of invasive gastrointestinal zygomycosis that occurred in a heavily immunosuppressed liver transplant recipient 5 days after retransplantation and that presented as gastric perforation. Despite aggressive surgical and antifungal therapy, the patient died. We review 46 cases of invasive zygomycosis in solid-organ transplant recipients. The rhinocerebral form of zygomycosis occurred in 57% of cases; the pulmonary, cutaneous, and disseminated forms each occurred in 13%; the renal form occurred in 2%; and the gastrointestinal form occurred in 2%. The infection ensued a median of 2 months after transplantation (range, 5 days to 8 years). Seventy-six percent of the patients had diabetes or had received antirejection therapy, mainly in the form of corticosteroids, before the onset of zygomycotic infection. The mortality for patients who received antifungal therapy and/or who underwent surgery was 50% for those who had rhinocerebral zygomycosis, none for those who had pulmonary and cutaneous zygomycosis, and 100% for those who had disseminated zygomycosis. Knowledge of the diverse clinical manifestations (including gastrointestinal involvement, as is illustrated by our case) and predisposing factors in transplant recipients with zygomycosis can aid in early recognition of this disease in this patient population.

A 49-year-old woman with diabetes mellitus rapidly developed necrotizing cellulitis with fat necrosis and vasculitis after minor trauma to the right arm. Zygomycosis was diagnosed histologically. The lesion responded to aggressive debridement, amphotericin B, and normalization of blood glucose. Cultures yielded structures characteristic of Saksenaea vasiformis only after transfer to saline agar.

Zygomycosis is a fungal infection which shows a definitive predisposition to attack the compromised host. It is usually associated with poorly controlled diabetes mellitus (DM). In the early infancy the cutaneous and gastrointestinal forms are the most frequent, in older children the most recognized form is that in which the primary impact of the infection is upon facial and intracranial structures. We report two cases of zygomycosis, the first patient was a 15 years old girl with a know systemic lupus erythematosus, and the second was a 14 years old boy with a insulin-dependent type I DM. Both were treated with anphotericin B and aggressive surgical intervention. The favorable outcome was attributed to a prompt diagnosis, early initiation of anphotericin B, surgical intervention and a control of the underlying illness.
