The surgical treatment of primary malignant lymphoma of the heart in a 43-year-old man is reported. The tumor was extensively resected together with the right atrial wall and both venae cavae, and the resulting defect was repaired with a bovine pericardial patch. The postoperative course was fairly stable for more than 7 months following surgery, under a regular chemotherapy regimen. The patient died of acute pneumonia on the 234th postoperative day. The autopsy findings confirmed the diagnosis of primary malignant lymphoma of the heart.

A 77-year-old man with chronic obstructive pulmonary disease was treated with low-dose methotrexate (7.5-15 mg per week). After 15 months a diagnosis of urothelial carcinoma of the bladder was made; after a further 6 months pneumonitis and pancytopenia developed. The patient died due to massive pulmonary hemorrhage. A malignant teratoma was diagnosed in a 65-year-old asthmatic man 16 months after initiation of methotrexate therapy (15 mg per week). The patient died 4 months later due to fulminant progression of the neoplasm. A third malignant neoplasm (dermal squamous cell carcinoma) was seen in a 64-year-old woman with rheumatoid arthritis after 13 months treatment with 7.5 mg methotrexate per week. These three cases, while obviously not proving a causal relationship between long-term treatment with low-dose methotrexate and development of malignant neoplasm, do call for stringent treatment criteria, close surveillance, and prospective studies.

The authors describe the finding of Nocardia asteroides from a haemoculture in a patient with right-sided pneumonia and several predisposing factors (TB, chronic bronchitis, anamnestic hepatitis, chronic hepatopathy, anaemia, ethylism and a neoplasm revealed in the final stage). Early bacteriological diagnosis and aimed antimicrobial therapy led to radical improvement of the very dramatic clinical condition. The authors discuss the possible higher incidence of the infectious agent, which previously was detected only very rarely.

Bronchoscopy was performed on a 68-year-old male patient with pulmonary tuberculosis, and revealed a yellow smooth polypoid tumor in the lumen of the left upper division bronchus. The histopathological diagnosis of the biopsy specimen was endobronchial lipoma. Since the patient did not have any symptoms due to the lipoma, we performed treatment for tuberculosis and continued careful observation of the tumor. During the subsequent 4 years, the patient developed no complications such as obstructive pneumonia, and the size of the tumor under bronchoscopic observation did not change. Endobronchial lipoma is a very rare benign tumor. Almost all reported cases have undergone operation or endoscopic surgery. This case is the first that was followed over 4 years without surgical procedure. The findings of follow-up bronchoscopic examination suggest that the growth rate of endobronchial lipoma is very slow. Furthermore, we reviewed 36 cases of endobronchial lipoma in the Japanese literature, including our case. Smoking seems to have a strong relation to the occurrence of the tumor. It is noteworthy that 6 cases had separate malignancies, but the direct relationship between endobronchial lipoma and such malignancies is unclear.

An 80-year-old male was admitted to our hospital because of multiple tumors in October 1989. A pathological diagnosis of non-Hodgkin's lymphoma (diffuse, medium-sized cell type) was made with the histological examination of his biopsied tumors. His clinical stage was stage IV A. Chemotherapy (CHOP) brought him to complete remission. In May 1990, relapse of non-Hodgkin's lymphoma was observed in the neck and both eyes. The diagnosis of uveitis due to involvement of lymphoma cells was confirmed by an aspiration biopsy of left aqueous humor. Complete recovery of his visual acuity was possible with additional chemotherapy, and lymphoma cells in his right aqueous humor were expelled completely, while his cervical tumor remained 1/3 of the original size. He eventually died of pneumonia on December 9th, 1990. Intraocular involvement of malignant lymphoma is rare in comparison with extraocular involvement. Especially, the patient who has only turbid aqueous humor as an ophthalmic sign is very rare. In this paper, we reported a case of lymphoma with intraocular involvement and discussed the mechanisms of infiltration of lymphoma cells into the aqueous humor and the therapy.

Children with malignant disease have an increased risk for bacterial infections. We investigated a possible correlation between septic episodes and decreased IgG subclass levels in 63 patients. At diagnosis 13 of 50 children showed decreased IgG subclass levels: 10x IgG4, 2x IgG1, and 1x IgG3 + IgG4 were reduced. Bone marrow infiltration by tumor cells did not increase the frequency of subclass reductions (4/25 with, 9/25 without bone marrow infiltration). The time course of subclass levels was followed during 37 febrile episodes (mainly fever of unknown origin, septicemia, pneumonia) of 23 children under cytostatic therapy. 6 patients showed transient low IgG subclasses: 2x IgG4, 1x IgG1, 1x IgG3, 1x IgG2 + IgG4, and 1x IgG1 + IgG3 + IgG4. Children with decreased IgG subclass levels appeared to occur more independently of leucopenia. In general, febrile episodes in children with subclass decreases did not last a longer period and did not occur more frequently than in children without IgG subclass deficiencies. In conclusion, the determination of IgG subclasses in cancer children at diagnosis or during chemotherapy did not add substantial information of prognostic or therapeutic relevance.

A total of 161 patients with lobar or segmental consolidation were examined by realtime ultrasound and Doppler ultrasound. Air bronchograms were detected in 141 patients, fluid bronchograms in 27 patients, and parapneumonic effusion in 74 patients. In 36 patients with necrotizing pneumonia, ultrasound detected microabscesses in 33 (91.7%) compared with the air-fluid levels detected by standard chest radiographs in 20 patients (55.6%; p less than 0.05). Of 31 patients with tumors causing obstructive pneumonitis, 29 (93.5%) had tumors detected by chest ultrasound, whereas only 11 patients (35.5%) had chest radiographs that suggested a tumor was causing the obstructive pneumonitis (p less than 0.05). Chest ultrasound was used to guide thoracentesis for parapneumonic effusion in 65 patients, with a 100% success rate. Twenty-six patients with necrotizing pneumonia underwent ultrasound-guided needle aspiration of microabscesses. The procedure was successful in 24 patients (92.3%), and 21 patients (80.8%) had microbiologic confirmation. Twenty patients with tumor-associated obstructive pneumonitis received needle aspiration biopsy under ultrasound guidance; 19 patients (95.0%) had the histology confirmed. Five patients with malignancy manifesting as pulmonary consolidation underwent a diagnostic ultrasound-guided needle aspiration biopsy. Five patients (3.8%) developed complications of minimal pneumothorax or mild hemoptysis in 132 episodes of needle aspiration. We conclude that ultrasonography is useful for the evaluation of pulmonary consolidation. It can also be used for needle aspiration guidance for etiologic diagnosis of patients with complicated pneumonia.

This review covers the papers that we believe represent the most interesting and innovative developments in hilar and mediastinal imaging over the past year. One of the most exciting of these is the expanded role for sonography in imaging extracardiac mediastinal pathology. A number of reports highlight its use in directing mediastinal biopsy, for tissue characterization, and for staging lymphoma. The comparative merits of CT and MR imaging in staging bronchogenic carcinoma have been further clarified. The past year has also seen further attempts to characterize tumor versus postobstructive pneumonitis or collapse using MR imaging and CT. Other useful clinical work includes the documentation of signs distinguishing paramediastinal lung masses from primary mediastinal pathology. References are also made to clinically relevant aspects of MR scanning and advances in imaging of the airway, particularly cine and high-resolution CT of the trachea.

Long-term data on the management of early breast cancer in Australia by conservative surgery and radiation therapy is limited. To examine this issue we reviewed our experience of 131 patients with Stage I or II breast cancer treated between November 1979 and December 1985. Ninety patients had a T1 tumor and 41 a T2 tumor. The extent of surgery varied from a local excision (LE), a wide local excision, to a quadrantectomy or partial mastectomy. Sixty-two per cent of patients also had an axillary dissection. One hundred and nineteen patients were treated using 6Mev photons to the whole breast (Median dose; 50 Gy) +/- regional nodes followed by a single plane Iridium-192 boost to the primary tumor site (median dose; 30 Gy). Ten patients did not receive a boost and two elderly patients were treated with an implant only. The median follow-up of surviving patients was 83 months (range, 51-133 months). Six other patients were lost to follow-up at a median of 48 months (range, 4-62). The pattern of first relapse is: breast alone, 7.0%; breast + distant, 0.75%; breast + nodes, 0.75%; regional nodes only, 0.75%; and distant disease, 18%. The extent of surgery did not influence the probability of a recurrence in the primary tumor region. The time to a breast recurrence ranged from 12 to 127 months (median, 61 months). The 5-year actuarial rate of a breast recurrence was 4.5%. The 5-year freedom from distant relapse was 80%. The complications of treatment were acceptable. These included rib fracture (5%), symptomatic pneumonitis (4%), fat necrosis or fibrosis requiring surgery (4.5%), severe arm edema (4.5%). The treatment of the axilla by both surgery plus radiation therapy was associated with a moderate or severe arm edema rate of 29% compared to 8% for surgery alone and 6% for radiation therapy alone. Our long-term data indicate that conservative surgery plus radiation therapy is associated with low rates of breast cancer recurrence which are independent of the extent of surgical resection. Complications were acceptably low provided that the axilla was treated by surgery or radiation therapy but not by both modalities.

A case of pleuropulmonary paragonimiasis that mimicked reactivation of pulmonary tuberculosis, pneumonia, and neoplasm occurred in a Laotian immigrant to Australia. The key to the diagnosis of this condition is awareness of the disease in persons from this region. The diagnosis was supported by enzyme-linked immunosorbent assay testing. The patient was successfully treated with praziquantel.
