Malignant lymphomas rarely arise initially in the paranasal sinuses, although these may become involved at a later stage of the disease. Such cases have rarely been reported because the paranasal sinuses are seldom subjected to routine postmortem examination, and the clinical signs often resemble those of suppurative sinusitis. The present paper reports 3 patients in whom the paranasal sinuses were affected by a malignant lymphoma (chronic lymphatic leukaemia). The histological findings are illustrated and the pathogenesis discussed.

The role of selected prior medical conditions in the etiology of hematopoietic malignancies was examined in a case-control study of members of two regional branches of the Kaiser Permanente Medical Care Program (USA). Past history of chronic infectious, autoimmune, allergic, and musculoskeletal disorders was abstracted from medical records for leukemia (n = 299), non-Hodgkin's lymphoma (NHL, n = 100), and multiple myeloma (n = 175) cases and matched controls (n = 787). Little difference was found between cases and controls for most of the chronic conditions evaluated, including sinusitis, carbuncles, urinary tract infections, pelvic infections, herpes zoster, asthma, rheumatoid arthritis, psoriasis, bursitis, and gout. Only three statistically significant elevated risks were found, i.e., with combined disc disease myeloma among patients with prior eczema and disk and other musculoskeletal conditions, and NHL following tuberculosis. Only two of these associations showed consistent patterns by sex and geographic region (myeloma with eczema and with musculoskeletal conditions). While prior history of eczema and musculoskeletal conditions may slightly increase risk of myeloma, this study provided little if any support for an association of chronic infectious, autoimmune, allergic, and musculoskeletal conditions with subsequent occurrence of the leukemias or NHL. Additionally, these data did not support a role for chronic antigenic stimulation, as defined in previous epidemiologic studies, in the etiology of hematopoietic malignancies.

Three patients developed severe respiratory syncytial virus pneumonia after bone marrow autograft for acute leukaemia. Clinically, the disease presents as interstitial or bilateral alveolo-interstitial pneumonia with hypoxaemia. Signs of ENT infection (otitis media, sinusitis) are present in 30 percent of the cases. In all 3 patients, the syncytial virus was isolated by direct immunofluorescence in bronchoalveolar lavage fluid. In 2 patients the infection began soon after the autograft, in deeply aplastic subjects, and required intubation and assisted ventilation. These 2 patients died despite inhalation of aerosolized ribavirin combined, in one of them, with ribavirin injections. In the third patient the infection began some time after the autograft and responded well to ribavirin in aerosols. In these three cases the viral infection occurred in an epidemic and nosocomial context. The respiratory syncytial virus is usually transmitted by the hands. Owing to the severity of this infection with lung involvement in immunodepressed patients, specific prophylactic measures should be taken side by side with the conventional measures.

Mucormycosis is a rare infection that occurs in immunocompromised patients. The rhinocerebral form presents in diabetics as a severe necrotizing sinusitis and is not frequent in patients with haematologic malignancies. Diagnosis requires direct examination and culture of biopsy specimens. Two patients with rhinocerebral mucormycosis and haematologic neoplasms (Non-Hodgkin's lymphoma and acute myeloblastic leukaemia) are described. Both patients had severe drug-induced neutropenia when the infection appeared. One patient died in spite of aggressive treatment with surgery and amphotericin.

This paper reviews the treatment and diagnosis of immunocompromised patients with fungal sinusitis at St Jude Children's Research Hospital. Sinusitis of all types was found to be more common in patients with hematopoietic neoplasms than in patients with solid tumors; 42% of patients with leukemia had abnormal sinus radiographs. Eight cases of pathologically proven fungal sinusitis were identified. All patients were undergoing chemotherapy for either acute myeloblastic leukemia or acute lymphoblastic leukemia and had neutrophil counts less than 100 cells/mm3. The most common findings were fever, facial pain, and abnormal sinus radiographs. Surveillance cultures of the upper aerodigestive system did not reliably predict sinus pathogens. An aggressive treatment approach consisting of early administration of amphotericin B (intravenously and via catheter irrigations of the sinuses) and surgical drainage is advocated. There was an 80% survival rate in patients in remission who were undergoing maintenance chemotherapy. All patients undergoing chemotherapy for relapse died.

The occurrence of adult T-cell leukemia-lymphoma in two New Orleans patients, one native-born, the other originally from Honduras, is reported. Both exhibited an unusual feature. One patient was diagnosed following an atypical episode of sinusitis and demonstrated lymphomatous infiltration of the nasopharynx. A second patient had a fulminant course complicated by severe diarrhea and was found to have both tumor involvement and cytomegalovirus inclusions in the colon. Both had high titers of antibodies to HTLV-I. A cell line with T-lymphocyte characteristics was established from the peripheral blood of the first patient. Such studies may help better establish the clinical course, detection, and epidemiologic features of this difficult disease.

Sinusitis tends to occur in immunodeficient and immunosuppressed patients during periods of severe leukopenia. This group of patients includes those with primary immunodeficiency diseases, patients with leukemia receiving chemotherapy, and those undergoing bone marrow transplantation or kidney transplantation. The clinical and radiographic signs may be minimal or initially unimpressive. Sinusitis due to Aspergillus, Phycomycetes, or Pseudomonas may be fulminant and even fatal, requiring extensive surgical procedures for control.

A patient with acute leukaemia developed a maxillary sinusitis and septicaemia with Branhamella catarrhalis during the period of bone marrow hypoplasia. One blood culture also grew Staphylococcus aureus. In the same period, the patient developed tender red skin lesions and disseminated intra-vascular coagulation. The patient recovered when therapy with high dosages of amoxicillin was instituted. At the same time, however, the bone marrow recovered.

A review of the hospital records of 71 patients from whose blood viridans streptococci were isolated showed that in 13 cases the patient's illness was definitely related to the bacteremia: 4 patients had endocarditis, 3 had pneumonia, 2 had peritonitis and 1 each had meningitis, a scalp wound infection, sinusitis and otitis media. The bacteremia may have contributed to the two deaths among these 13 patients. In 45 cases the viridans streptococci may have contributed to the patient's illness: 15 patients had an infection of the lower respiratory tract and 7 an infection of the upper respiratory tract, 8 were neonates with suspected septicemia, 3 had soft tissue infections, 3 had leukemia and sepsis, and 9 had miscellaneous infections; the bacteremia was unrelated to the two deaths in this group. In another 13 cases the viridans streptococci could not be related to the patient's illness. The species most frequently isolated were Streptococcus mitis, S. sanguis II and S. MG-intermedius. The outcome of the bacteremia was generally good, even among the 11 patients not treated with antibiotics. When viridans streptococci are cultured from a single blood sample, further samples of blood and, if feasible, specimens from the associated focus of infection should be obtained for culture; further blood cultures are especially important in cases of suspected endocarditis.

Herein we report the successful treatment of invasive aspergillosis with the liposomal amphotericin B (AMB) formulation, Amphotericin B Lipid Complex (ABLC). This investigational compound was employed in a 50-year-old patient with acute myelomonocytic leukemia complicated by prolonged, treatment-induced granulocytopenia and documented Aspergillus flavus sinusitis with signs of disseminated aspergillosis. The patient demonstrated radiographic signs of pulmonary aspergillosis and biochemical signs of hepatic involvement that were resistant to a 23 day course of conventional AMB (Fungizone) therapy. Following therapy with ABLC her fever abated, her chest X-ray findings improved, and her hepatic function tests improved with eventual resolution.
