The results of a retrospective autopsy study of 115 adult patients with haematological or lymphoreticular malignancies or who had undergone transplantation procedures, are presented. The overall incidence of infection was 65%, 123 infections being detected in 75 patients. The bulk of the infections involved the gastro-intestinal and respiratory systems, other systems being considerably less frequently affected. Patients who had received allografts and subsequent immunosuppression had the highest incidence of viral inclusions, especially cytomegalovirus. Candida infections were more common than aspergillosis, and severe fungal infections were most frequent in patients with acute leukaemia who had been treated aggressively. The only other mycosis detected was cryptococcosis. Bacterial pneumonia was the most frequent infection over-all (36%). Tuberculosis, pyelonephritis and Pneumocystis pneumonitis were also encountered.

A patient with acute myelocytic leukemia who had a chronic febrile illness during the induction of remission of leukemia developed asymptomatic discrete pulmonary infiltrates which rapidly evolved into cavities containing homogeneous opacities. Over the next five weeks, the cavities resolved without specific treatment. The patient subsequently passed large fungus balls in the urine, and the diagnosis of disseminated aspergillosis was made. A course of intravenous amphotericin B therapy was completed without complications. This case demonstrates the importance of culturing urine specifically for fungal organisms in the immunosuppressed host.

Infectious mural endocarditis is uncommon and not well documented. The clinical setting and pathologic features of five patients with Aspergillus mural endocarditis are described. Leukemia, carcinoma, renal transplantation, and hepatic failure were the primary diseases. Associated conditions include high-dose corticosteroids, cytotoxic therapy, renal failure, gram-negative sepsis, and endotracheal intubation. All patients received prolonged antibiotic therapy or treatment with three or more antibiotics. All had clinically undetected aspergillosis and severe fungal pneumonia. Fungal myocardial abscesses were present in each patient. Aspergillus mural endocarditis developed in more than 40% of patients with cardiac aspergillosis. Endocardial vegetations were contiguous with underlying myocardial infection; yet they may develop initially as a subendocardial focus rather than from a myocardial abscess. Aspergillus mural endocarditis progressed to destroy the mitral valve ring and served as a source of mycotic embolization to vital organs.

To measure the incidence in the United States of systemic mycoses necessitating hospitalization, we reviewed discharge records of 1,875 hospitals participating in the Professional Activity Study of the Commission on Professional and Hospital Activities. Projected incidence rates in 1976 ranged from 23.0 per million for histoplasmosis to 0.2 per million for blastomycosis. High prevalences of leukemia or lymphoma (5.9% to 10.2%) or of other malignancies (9.9% to 13.2%) were recorded in patients with aspergillosis, candidasis, or cryptococcosis. High prevalences of chronic obstructive lung disease (9.6% to 9.9%) were recorded in those with aspergillosis or histoplasmosis. Marked increases from 1970 to 1976 were found in the incidence of aspergillosis (158%), actinomycosis (92%), cryptococcosis (78%), and coccidioidomycosis (74%). Increasing numbers of persons with immunosuppressive conditions, migration of susceptible persons into hyperendemic areas, and aging of the population contributed to the increases.

Primary cutaneous aspergillosis is rare. In this report we describe a primary skin infection by Aspergillus flavus in a child with leukemia. The lesions were characterized by erythematous macules and papules associated with pain and itching, followed by a rapid progression to ulcers and central black eschars with a raised erythematous border. A favorable response to topical nystatin therapy was observed. The multiple cutaneous lesions seen in our patient were most likely due to primary inoculation near the site of intravenous infusion with subsequent local lymphatic spread.

The frequency of precipitating antibodies to Aspergillus, thermophilic actinomycetes, and pigeon serum was studied in hospitalized patients and in employees of the state of Wisconsin. Precipitins to Aspergillus were detected in 9 per cent of the hospitalized patients and 3 per cent of the state employees. The majority of the serologically reactive hospitalized patients were diagnosed as having carcinoma with metastases, lymphoma, or leukemia. No evidence of hypersensitivity pneumonitis or invasive aspergillosis was seen in these patients. The frequency of antibodies to thermophilic actinomycetes (3 per cent) and pigeon serum (1 per cent) was similar in both groups. Women from 17 to 25 years of age and men from 52 to 66 years of age demonstrated an increased incidence of positive precipitins.

During a 14 month period there were 364 episodes of bacteremia and fungemia at Memorial Sloan-Kettering Cancer Center. The first nine months of the study were retrospective, and the next five prospective. In patients with leukemia or lymphoma (group 1), Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus were the most frequently isolated organisms. The mortality in this group was 40.5 per cent. In the patients with solid tumor (group 2), Esch. coli, Staph. aureus, Bacteroides sp. and Candida sp. were most frequent. Mortality was 27.8 per cent. The source of infection in both groups was often indeterminate. High mortality was associated with pulmonary and intraabdominal infection and with Ps. aeruginosa, K. pneumoniae or polymicrobic sepsis. Factors of prognostic significance were the causative microorganism, source of infection and shock. Although mortality was higher in patients with leukopenia than in those with normal leukocyte counts, the differences were not significant. The mortality in this series was low considering the severity of the underlying diseases and the immunosuppressed state of many of the patients. In a prospective, randomly controlled study, mortality was further diminished by infectious disease consultation at the time the positive blood culture was reported. Severe fungal superinfection, predominantly aspergillosis and candidiasis, was found in 52 per cent of the autopsy patients with leukemia or lymphoma (group 1), but in only 8 per cent of those with solid tumors (group 2).

Thirty-six consecutive patients with cancer who met the classical criteria for fever of unexplained origin (FUO) were identified. A total of 18 patients had infections including all 12 with leukemia, four of 12 with Hodgkin's disease, and two with solid tumors. Fungal infections were found in nine: histoplasmosis, three; candidiasis, three; and aspergillosis, systemic sporotrichosis, or cryptococcal meningitis, one each. Six patients had unresolved pyogenic infections and one had tuberculous pericarditis. Two others had viral etiologies. Granulocytopenia was significantly more common in the FUO patients with documented infections. Clinical or laboratory abnormalities suggesting involvement of a specific organ or organ system provided important clues indicating infections. Morphological examination of biopsy specimens, with cultures, was the best method for diagnosis. In 18 patients, 12 with lymphomas and 6 with solid tumors, only the neoplasm appeared responsible for the fever. In these patients there was a paucity of abnormalities indicating organ system involvement with infection. Regardless, physicians' diagnostic efforts should not be deterred in such patients. Repeated thorough evaluations for infection are warranted.

Two children with acute leukaemia developed histologically confirmed invasive aspergillosis within 2 weeks after onset of polychemotherapy. One child had received only prednisone and one pulse of vincristine and daunorubicin before. This child showed classical roentgenographic signs of aspergilloma following an upper pulmonary lobe infiltration. The second patient developed caecal aspergillosis obscured by clinical signs of appendicitis. He died of disseminated aspergillosis several weeks later in spite of systemic antifungal therapy. Both case reports illustrate that the possibility of invasive aspergillosis must also be expected in young patients soon after onset of induction chemotherapy.

A 59-year-old male was admitted to our hospital in Jan. 1991 with complaints of general malaise and palpitation. Laboratory findings on admission showed anemia, thrombocytopenia and leukopenia consisted of 2.0% myeloblasts with Auerbodies. The bone marrow study showed granuloid hyperplasia with 45.5% myeloblasts. The diagnosis of acute myeloblastic leukemia (M1) was made. After BHAC-AMP therapy, he obtained complete remission. However, he complained of fever and cough, and his chest X ray film showed a focal infiltrative shadow in the right upper lung field. Antibiotics for bacteria and fungus were administered and the abnormal shadow improved in a week. However, as he had hemosputum, the bronchoscopic examination was performed, and multiple ulcers covered by yellow-white tissue were revealed on the wall of the trachea and bilateral main bronchi. Biopsy specimens obtained by transbronchial biopsy showed bronchial aspergillosis. Though intravenous infusion and inhalation of amphotericin B were effective for aspergillosis, he had a relapse of the leukemia and died in autumn, 1991.
