A 52-year-old man with mild diabetes and acute stem cell leukaemia developed an orbitofacial mucormycosis. Cultures showed the fungus to be Rhizopus oryzae. Vigorous treatment with amphotericin B and other bactericidal and bacteriostatic antibiotics for a concurrent sepsis failed to suppress the infections, and the patient died. On post-mortem examination characteristic haematoxylin-staining, broad, aseptate fungal hyphae were found in the right eye, orbit, and lung. A striking and unusual feature of this case is the presence of brightly birefringent crystals within the severely degenerated eye. These were found by histochemical staining and x-ray diffraction studies to be calcium salts of fatty acids, apparently liberated from necrotic adipose tissue of the orbit.

We analysed the case records of 75 patients with acute myeloid leukaemia treated at our institute from January 1984 to December 1988 to see the pattern and severity of infections and their relationship with granulocytopenia. A total of 184 febrile episodes (mean 2.45) were recorded; 153 (83.15%) were associated with granulocytopenia while 31 (16.84%) were without granulocytopenia. Among granulocytopenic patients, infections could be documented microbiologically in 58.2% and clinically in 30.0% of episodes. In the remaining 41.8% of episodes, no clinical, radiological or microbiological evidence could be found out. The various sites of infection were: septicaemia 21 (13.72%), disseminated fungal infections 4 (2.6%), upper respiratory tract 21 (13.7%), chest 58 (37.9%), gastrointestinal tract 8 (5.2%), genitourinary (7.2%), soft tissues 5 (3.2%) and skin cellulitis 7 (4.6%). Microbiologically, gram negative organisms (Klebsiella pneumoniae, E coli, Pseudomonas aeruginosa) were most common, followed by gram positive (Streptococcal faecalis, Staphylococcus aureus, Staph albus, Staph epidermidis). Four patients had disseminated fungal infection: candida 2, aspergillus *1, mucormycosis *1. Among non neutropenic febrile episodes, the sites infected were: septicemia 2 (6.4%), chest 9(29.0%), upper respiratory tract 1 (3.2%), gastrointestinal 1 (3.2%), soft tissue 1 (3.2%), drug fever 3 (9.6%) and fever of unknown origin 14 (45.2%).

Cutaneous mucormycosis is a rare but often fatal infection in trauma patients. We retrospectively reviewed a 9-year experience with mucormycosis among injured patients. Eleven patients had biopsy- or culture-proven mucormycosis. Nine patients were victims of blunt trauma, two patients had burns measuring greater than 50% TBSA. No patient was at increased risk because of underlying disease or immunosuppression prior to injury. All 11 patients had open wounds on admission. Four patients died of mucormycosis. All nonsurvivors had phycomycotic gangrenous cellulitis of the head, the trunk, or both. In contrast, survivors had involvement of only the extremities. Because of underlying disease, contaminating wounds, antibiotic use, or immunocompromise secondary to shock and sepsis, trauma patients are at risk of developing mucormycosis. To successfully treat mucormycosis, diagnosis must be prompt and accompanied by aggressive debridement and parenteral administration of amphotericin B.

Nonmalignant causes of Pancoast's syndrome are extremely rare. The authors report the case of a 32-year-old man, receiving treatment for acute lymphoblastic leukemia, who had a clinical picture resembling that of Pancoast's syndrome. Invasive mucormycosis was diagnosed as the cause of the syndrome at emergency thoracotomy undertaken to control massive hemoptysis. In spite of adequate treatment, the patient died 5 weeks postoperatively of overwhelming sepsis. A review of the literature disclosed only two other similar cases. The authors conclude that the development of Pancoast's syndrome in the immunosuppressed patient should raise suspicion of an invasive fungal infection. A precise early diagnosis may allow successful, specific antifungal therapy to be instituted.

A post-operative diabetic patient who had been treated for Serratia marcescens bacterial sepsis developed recurrent thrombosis of the left femoral artery following intra-arterial instrumentation. Pathological examination of arterial thrombus ultimately demonstrated invasive mucormycosis of the femoral artery and cultures of this material grew Rhizopus oryzae. The occurrence of cutaneous and subcutaneous mucormycosis is reviewed, as well as recently recognized nosocomial risk factors for mucormycosis, such as elasticized bandages and wound dressings.

Mucormycosis in two patients with multiple-organ failure appeared as a cutaneous lesion and spread rapidly. In the first case, wet mounts and potassium hydroxide preparations were unhelpful, but a punch biopsy specimen established the diagnosis. Prompt and extensive debridement and amphotericin B administration arrested the infection. In the second case, virulent progression of the lesion occurred despite limited amputation, debridement, transfer factor, and amphotericin B, but finally responded to further amputation. Diagnosis was made by histologic examination of infected tissue. Both patients shared the following predisposing factors: sepsis, low blood flow, acidosis, multiple-organ failure, and multiple-antibiotic therapy. Although the mucormycosis was controlled, as confirmed in the first case at autopsy and in the second case by clear margins following reamputation, the outcome was fatal in both cases due to other features of multiple-organ failure.

This presentation reviews the course of burn wound sepsis in a group of 621 acute patients treated at the Shriners Burns Institute, Cincinnati Unit, between 1970 and 1976. During this period of time, the overall mortality rate fell from 14% in 1970 to 3 and 5%, respectively, in 1975 and 1976. Staphylococcus aureus was the most commonly recovered organism from the burn wound, colonizing 85% of the burn patients. Beta hemolytic streptococcus represented a potential threat despite the fact that it was recovered from only 5 to 10% of the patients. Pseudomonas aeruginosa showed a decrease in colonization during the period of this study, from 50% of the wounds in 1970 to 21% in 1976. Candida albicans was the fungal organism most commonly recovered from the burn wound and from the blood stream. Fifteen deaths occurred in this group as a result of invasive infection, one from S. aureus, five from P. aeruginosa, two from Klebsiella-Enterobacter, and one from Escherichia coli, as well as six fungal deaths, five from Candida albicans and one from mucormycosis. Therapeutic measures used to control burn wound sepsis consisted of prevention of contamination from exogenous sources, control of burn wound pathogens, early recognition of invasive burn wound sepsis, aggressive management of the burn wound, and optimal nutritional support. During this period the extent of burn associated with a survival of 50% has risen from 50% in 1970 to 80% in 1976. This improvement in survival is directly related to progressive improvement in local and systemic measures available for the control of infection.

Mucormycosis is an opportunistic fungal infection that commonly begins by invading the respiratory tract. The purpose of the present study was to define the clinical presentation of pulmonary mucormycosis and to evaluate current treatment regimens. Thirty patients treated at our institution and 225 cases reported in the literature were reviewed. For the combined groups, the mean age at presentation was 41 +/- 21 years and associated medical conditions included leukemia or lymphoma (37%), diabetes mellitus (32%), chronic renal failure (18%), history of organ transplantation (7.6%), or a known solid tumor (5.6%). The in-hospital mortality was 65% for patients with isolated pulmonary mucormycosis, 96% for those with disseminated disease, and 80% overall. The mortality in patients treated surgically was 11%, significantly lower than the 68% mortality in those treated medically (p = 0.0004). The most common causes of death were fungal sepsis (42%), respiratory insufficiency (27%), and hemoptysis (13%). Pulmonary mucormycosis has a high mortality; however, antifungal agents appear to improve survival. In addition, surgical resection may provide additional benefit to patients with pulmonary mucormycosis confined to one lung.

Primary renal mucormycosis is a rare infection capable of acute illness with sepsis. Few cases have been reported. We report a case of an acute primary renal mucormycosis and review the published reports. The incidence of primary renal mucormycosis has risen in recent years. The most frequently reported underlying predisposing disorders are human immunodeficiency virus infection, intravenous drug abuse, and diabetes mellitus. Primary renal mucormycosis should be suspected in patients with an immunocompromising illness or particular risk factors, when persistent flank pain and fever with sterile urine not responding to appropriate antibiotics are associated with enlarged heterogeneous kidneys.
