Primary cutaneous mucormycosis in a premature infant: case report and review of the literature.

Mucormycosis is an uncommon infection caused by fungi of the order Mucorales, family Mucoraceae, and almost always occurs in individuals with predisposing factors such as diabetes mellitus, metabolic acidosis, or immunodeficiency states. Although mucormycosis is a rare infection in childhood, sporadic cases of skin infections have been described in young infants and older children; primary skin infection has been associated with multiple nosocomial outbreaks caused by contaminated elastic bandages. In all reported cases involving premature infants, the elimination of the infection involved surgical debridement. We report for the first time successful conservative treatment with intravenous amphotericin B in a premature infant with primary cutaneous infection caused by Rhizopus oryzae.

[Orbital and ocular mucormycosis].

A case of mucormycosis in a 46-year-old woman with acute lymphoblastic leukemia is described. The typical clinical findings, diagnostic procedures, and therapeutic considerations are discussed. Mucormycosis is a rare complication in immunocompromised patients. Early ophthalmological diagnosis and rigorous therapy may improve the course of this otherwise fatal disease.

[Rhinocerebral mucormycosis during deferoxamine therapy].

A 24-year-old woman had been in full remission of an acute myeloid leukaemia since 1988, but she required regular erythrocyte and platelet transfusions for pancytopenia. To counteract a progressive siderophilia due to the transfusions (ferritin levels of about 10,000 ng/ml) deferoxamine was intermittently given intravenously (5 g after each transfusion). Seven months after the start of this treatment the patient was hospitalized because of severe left-sided facial pain as well as reddening and swelling in the periorbital region. As maxillary and frontal sinusitis was suspected, antibiotics were administered (at first three times daily 2.2 g amoxicillin and clavulanic acid, then two times daily 300 mg rifampicin and 200 mg ciprofloxacin). Nonetheless, orbital phlegmon developed within a few days with protrusion and blindness of the left eye necessitating a decompression operation. Material obtained at operation revealed rhinocerebral mucormycosis. After 3 weeks of antimycotic treatment with both amphotericin B (1 mg/kg.d) and flucytosine (150 mg/kg.d) the mucormycosis healed without the necessity of extensive and disfiguring removal of necrotic tissue. But the blindness in the left eye, caused by occlusion of the central artery, was irreversible.

[Rhino-cranial mucormycosis in acute leukemia].

The diagnosis of acute lymphatic non-T-non-B leukaemia of common ALL type was confirmed in a 22-year-old woman. Cytostatic treatment brought full remission for 21/2 years. Renewed cytostatic treatment for recurrence brought about a mucormycosis in the mid-face region during a period of protracted agranulocytosis, despite antibiotic prophylaxis with ketoconazole and cotrimoxazole. The causative mucor organism was demonstrated in smears and biopsy material. The infection was successfully treated with i.v. amphotericin B and débridement of the affected tissue. There remained large tissue defects in the region of gum, nose, upper lip and right oral cavity. Previously the mortality rate of mucormycosis in the course of leukaemia was 100%.

Mucormycosis in an immunocompetent patient: follow-up of 1 year after treatment.

Mucormycosis is a rare acute fatal fungal infection. It is typically observed in diabetic or immunocompromised patients but not in systemically healthy individuals. Here, we describe an unusual mucormycosis case in an immunocompetent patient who had clinical signs of a maxillary sinusitis and associated osteomyelitis at the first examination. He was treated by surgery and removal of the necrotic bone and amphotericin B medication. At 1-year follow-up he shows complete recovery.

Liver and brain mucormycosis in a diabetic patient type II successfully treated with liposomial amphotericin B.

A case of liver and brain mucormycosis in a 73-y-old diabetic patient is described. The patient presented with fever and a moderate, tender hepatomegaly and a C/T scan examination of the abdomen and brain showed multiple hepatic and cerebral nodular lesions. The largest of the liver lesions was aspirated and broad hyphae of mucor were demonstrated in the purulent material obtained. The patient was treated successfully (for 40 d) with intravenous liposomal amphotericin B and then with itraconazole for 3 months. To our knowledge, this is the first case of a diabetic patient with both liver and brain mucormycosis who has been treated successfully.

Successful treatment of pulmonary mucormycosis in an allogenic bone-marrow transplant recipient with combined medical and surgical therapy.

Mucormycosis is a rare, but severe, complication in allogenic bone-marrow recipients with a mortality rate of about 80%. Moreover, its incidence appears to have increased within the last decade. We report a case of pulmonary and nasal mucormycosis in a 55-y-old patient, which occurred 1 y after BMT. Treatment combining 4 months of amphotericin B, early surgical resection of infected tissue and discontinuation of immunosuppressive treatment allowed the cure of this mould infection.

Central venous catheter-associated fungemia secondary to mucormycosis.

Mucormycosis can cause fatal infections in immuno-compromised persons. Rhinocerebral and pulmonary disease predominate. Diagnosis is challenging, dissemination frequent, and mortality high. Positive blood cultures are rare. We report the first case of central venous catheter-associated mucormycosis fungemia (Mucor circinelloides). Early diagnosis and multi-modal therapy led to clinical and microbiological cure.

Prior invasive pulmonary and cerebellar mucormycosis is not a primary contraindication to perform an autologous stem cell transplatation in leukemia.

Mucormycosis infections, caused by fungi of the families Rhizopus, Mucor or Absidia, are typically rapidly progressive and often fatal. We report a 27-year-old male with acute myeloid leukemia (AML) developing an invasive pulmonary-CNS mucormycosis during the neutropenic period after salvage induction chemotherapy; the infection was successfully controlled with surgery and antifungal therapy. The patient received two courses of consolidation chemotherapy and underwent autologous stem cells transplantation (ASCT) while receiving secondary antifungal systemic prophylaxis with liposomal Amphotericin B (L-AMB, Ambisome). There was no clinical, radiological or microbiological evidence of mycotic reactivation during the bone marrow transplantation (BMT) procedure.

Mucormycosis, a threatening opportunistic mycotic infection.

Mucormycosis is a rare and invasive mycotic opportunistic infection, occurring mostly in predisposed patients, mainly diabetics and immunocompromised individuals. The evolution of this fungal infection is frequently fatal unless aggressive treatment is started, or predisposing factors are handled. Our first patient was a known diabetic who had ketoacidotic coma at admission, complicated with pulmonary mucormycosis, and needed surgical resection followed by antimycotic therapy. The second patient did not survive his severe aplastic anemia (with neutropenia) and hemochromatosis (treated with desferrioxamine), complicated with a systemic Rhizopus infection, despite treatment with amphotericin B and granulocyte-colony-stimulating factors.

Leukopenia with granulocytopenia in experimental mucormycosis (Rhizopus oryzae infection).

Mucormycosis was produced in rabbits with sustained, severe leukopenia and granulocytopenia induced by repeated injections of nitrogen mustard. Initially, these animals developed extensive fungus lesions at the site of inoculation which later became granulomatous and tended to heal. Only the early phases of host resistance appeared impaired by the virtual elimination of the polymorphonuclear leukocyte as a factor in the host response. Despite the persistent leukopenia and granulocytopenia, the later phases of host resistance resembled those of the normal animal. Thus, the behavior of the infection in this experiment differs greatly from the unchecked progression of mucormycosis in the metabolically abnormal animal with acute alloxan diabetes. The differences in the course of the disease and in the morphologic appearance of the lesions indicate that metabolic alterations in the host affect all phases of host resistance and not only the polymorphonuclear leukocytic response.

Isolated case of Ebola hemorrhagic fever with mucormycosis complications, Kinshasa, Democratic Republic of the Congo.

A patient with undiagnosed Ebola (EBO) hemorrhagic fever (EHF) was transferred from Kikwit to a private clinic in Kinshasa, Democratic Republic of the Congo. A diagnosis of EHF was suspected on clinical grounds and was confirmed by detection of EBO virus-specific IgM and IgG in serum of the patient. During the course of the disease, although she had no known predisposing factors, the patient developed a periorbital mucormycosis abscess on eyelid tissue that was biopsied during surgical drainage; the abscess was histologically confirmed. Presence of EBO antigen was also detected by specific immunohistochemistry on the biopsied tissue. The patient survived the EBO infection but had severe sequelae associated with the mucormycosis. Standard barrier-nursing precautions were taken upon admission and upgraded when EHF was suspected; there was no secondary transmission of the disease.

Pulmonary mucormycosis as a complication of chronic salicylate poisoning.

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.

Cerebral mucormycosis associated with intravenous drug use: three case reports and review.

We describe three cases of cerebral mucormycosis in intravenous drug users and review 22 previously reported cases. Involvement of the basal ganglia was demonstrated in all but two cases. Seven of the 10 patients tested for antibodies to the human immunodeficiency virus (HIV) were seronegative. Eight of the 25 patients survived and were discharged from the hospital; for 7 of 10 patients, cultures of brain lesions yielded Rhizopus arrhizus. The radiographic findings varied, and in most cases, no or minimal contrast enhancement was seen in the initial computed tomography scans. Although uncommon, the diagnosis of cerebral mucormycosis should be considered when basal ganglia lesions are present in an intravenous drug user, regardless of previous exposure to HIV.

Fatal genitourinary mucormycosis in a patient with undiagnosed diabetes.

We present what we believe is the first report in the world literature of penile necrosis due to mucormycosis, a rare and often fatal fungal infection. This case of rhizopus mucormycosis began with a penile lesion in a 27-year-old patient with undiagnosed diabetes; it led to necrosis of the phallus, lower urinary tract, rectum, and pelvic musculature and finally to death. Despite repeated aggressive surgical debridement in conjunction with medical therapy, we were unable to halt the progression of the fungal and synergistic bacterial infections.

Survival from sino-orbital mucormycosis due to Rhizopus rhizopodiformis.

We report the first case of sino-orbital mucormycosis caused by Rhizopus rhizopodiformis. Therapy consisted of conservative surgical drainage and intravenous amphotericin B. The patient, an insulin-dependent diabetic, survived her infection with minimal residual deformity. This case and a literature review suggest that infection due to R. rhizopodiformis in diabetics might be more amenable to treatment than mucormycosis caused by other species of fungi. Speciation of such fungi would permit the determination of species specific mortality rates, and may be of therapeutic and prognostic value.

Nonsurgical cure of pulmonary mucormycosis.

Pulmonary mucormycosis is an unusual infection which appears to occur with increased frequency in diabetics. We report the development of pulmonary mucormycosis in an adult onset diabetic which resolved with medical therapy alone. Computerized tomography proved useful in assessing his response to therapy.
