Single lung transplantation. Morphological surveillance by transbronchial biopsy.
Seven cases of single lung transplantation are reported. The recipients were all below 60 years of age and severely disabled with end-stage lung disease. Transplantation was performed according to ABO blood group compatibility and negative lymphocytotoxic cross-match between donor and recipient irrespective of HLA mismatch. Recipients' diagnoses were sarcoidosis (3), alfa-1 antitrypsin deficiency (3), and idiopathic emphysema (1). Mean recipient age was 48 +/- 2.4 years (range 45-52). Donor age was 29.7 +/- 5.6 years (range 16-49). The immunosuppressive regimen included cyclosporin A, azathioprine, steroids and rabbit antithymocyte globulin. Excellent graft function was achieved. Six patients survived the postoperative period and are alive 4-18 months posttransplant. One patient died after the operation due to pneumonia with respiratory distress syndrome. Graft function was also monitored by transbronchial biopsy, and 57 biopsy procedures were performed without fatal complications. Acute cellular rejection was seen in 16 biopsy specimens from 5 recipients (grade 1 and 2 rejection in 14, grade 3 rejection in 2). Neither severe rejection with septal necrosis (grade 4) nor obliterative bronchiolitis was seen. The rejection rate was 0.03 episodes per patient/month. In contrast to other reports, episodes of cellular rejection occurred throughout the observation period, and were not mainly limited to the first 4 months posttransplant. Graft vascular occlusive disease or chronic vascular rejection was found in 6 biopsy specimens from one recipient. Five patients experienced 7 episodes of cytomegalovirus infection. The cytomegalovirus infection rate was 0.01 episodes per patient/month. The incidence of infection was significantly lower compared to previous studies of rejection in other lung graft combinations. Both infections and rejection episodes may contribute to the development of obliterative bronchiolitis. Almost one third of the specimens (30%) showed lymphocytic bronchitis without perivascular inflammation. The absence of perivascular infiltrates and exclusion of infectious agents leaves in question the aetiology of this inflammation. The lymphocytic bronchitis could be ischaemic, related to aspiration, or represent recurrent sarcoidosis, or, in fact, express bronchial rejection. All biopsy specimens regarded as rejection with cellular infiltrates in the lung parenchyma also showed a lymphocytic bronchitis. The impact of HLA mismatch on cellular and vascular rejection is unclear. Transbronchial biopsy is a reasonably safe and reliable method in the diagnosis of rejection and infection in single lung transplantation.

[A case of pulmonary cryptococcosis with lung cancer in a pulmonary lobe].
A 63-year old female was admitted because of an abnormal shadow on chest X-ray film. Chest CT showed a nodular shadow in the right S6 and a patchy shadow in the right S10. Right lower lobectomy was performed under a diagnosis of lung cancer made by TBLB in the right S6. Pathological examination of the resected lung revealed papillary adenocarcinoma in the right S6 and numerous cryptococci in the right S10. No cryptococcal infection was found in the resected lymph nodes.

[Aspergillosis with non-cavitary lung cancer].
Growth of Aspergillus was observed in the necrotic tissue of non-cavitary lung cancer. Case 1 was a 60-year-old male complaining of cough and fever and was found to have left lower lobe atelectasis on chest X-ray. Bronchoscopic examination showed the yellow soft lesion occluding the left upper and lower lobe bronchus. Specimen from the lesion demonstrated adenocarcinoma and hyphae of Aspergillus in the necrotic tumor. Case 2 was a 53-year-old male who was found to have a left upper lobe mass by chest X-ray screening. Bronchoscopic examination showed the yellow polypoid lesion occluding the left upper division bronchus. Pneumonectomy was done and resected specimen of the lesion demonstrated adenocarcinoma and the hyphae of Aspergillus growing in both necrotic tissue and cancer tissue. As both patients had hyphae of Aspergillus in the necrotic tumor, it is considered that the presence of necrosis may cause the growth of Aspergillus.

Necrotizing pneumonia caused by Penicillium chrysogenum.
We report a case of necrotizing pneumonia due to Penicillium chrysogenum in a 57-year-old woman operated on for lung cancer. The residual right lower pulmonary lobe was infiltrated by Penicillium chrysogenum. The patient underwent a second pulmonary right lobectomy and was successfully treated with oral itraconazole. To our knowledge, this is the first case of pneumonia due to P. chrysogenum.

Posttransplantation disseminated coccidioidomycosis acquired from donor lungs.
A North Carolinian developed fatal coccidioidomycosis immediately after bilateral lung transplantation. The donor had previously traveled to Mexico, and the recipient had no travel history to an area where Coccidioides immitis is endemic. Immunosuppressive therapy of the transplant recipient likely reactivated latent Coccidioides infection in the donor lungs, leading to posttransplant coccidioidomycosis.

Atypical isolate of Cryptococcus neoformans cultured from sputum of a patient with pulmonary cancer and blastomycosis.
Cryptococcus neoformans was isolated repeatedly from a patient with epider-moid carcinoma and pulmonary blastomycosis. The isolate was atypical in that it had only a minute capsule, caused persistent infection but no perceptible disease in mice, and initially appeared not to assimilate trehalose. Only after an incubation of 2 to 3 weeks did utilization of this substrate become apparent.

Multiple chronic benign pulmonary nodules.
Four cases are discussed in which were found unusual multiple chronic pulmonary nodules: leiomyomatous hamartomas, rheumatoid nodules, multiple histoplasmomas, and possible multiple plasma cell granulomas (hyalinizing pulmonary nodules). In each case the initial impression of metastic malignancy was countered by more than 2 years' observation, during which time the lesions appeared to be benign. Histologic examination is necessary to exclude malignancy, although a definitive diagnosis may be difficult to establish.

Solitary pulmonary nodule: high-resolution CT and radiologic-pathologic correlation.
Edge and internal characteristics of pulmonary nodules evaluated with high-resolution computed tomography (HRCT) were correlated with the pathologic specimens in 93 patients. Speculation correlated pathologically with irregular fibrosis, localized lymphatic spread of tumor, or an infiltrative tumor growth pattern and was observed in six of 11 benign nodules (55%) and 74 of 85 malignant nodules (87%). Pleural tags were observed in three benign nodules (27%) and 49 malignant lesions (58%); pathologically, these represented fibrotic bands usually associated with juxta-cicatricial pleural retraction. Bubblelike areas of low attenuation within the nodule were observed in 21 malignant lesions (25%) and only one benign nodule (9%). They were observed most commonly in bronchioloalveolar carcinomas (seven of 14) and were due either to patent small bronchi or small, cystic spaces within neoplastic glands. Malignant nodules as a group were larger than benign lesions (P = .02) and more commonly demonstrated a spiculated contour (P less than .05), lobulation (P less than .001), and inhomogeneous attenuation (P less than .05).

Opportunistic bronchopulmonary infections after lung transplantation: clinical and radiographic findings.
PURPOSE: To assess clinical and radiographic findings in opportunistic bronchopulmonary infections after lung transplantation. MATERIALS AND METHODS: Forty-five episodes of opportunistic bronchopulmonary infection occurred in 27 (35%) of 77 lung transplant recipients during a 4-year period. Causative organisms, radiographic patterns, and mortality were reviewed. RESULTS: Cytomegalovirus (CMV) was the most common pathogen (25 episodes), followed by Aspergillus species (seven episodes), Pneumocystis carinii (six episodes), herpes simplex virus (four episodes), Mycobacterium avium complex (two episodes), and M tuberculosis (one episode). Eighteen of the 25 episodes (72%) of CMV pneumonitis occurred in the first 4 months after transplantation; 24 (96%) occurred within the 1st year. Radiographic patterns of symptomatic CMV pneumonitis were diffuse haziness (60%), focal haziness (33%), and focal consolidation (7%). Aspergillus species locally invaded a necrotic bronchial anastomosis in three patients, each within 4 months of transplantation. P carinii was seen as focal haziness and caused no symptoms. Radiographic findings, when present, were seen almost exclusively in the transplanted lung. Despite three deaths attributable to opportunistic bronchopulmonary infection, the difference between the survival rates of patients with and those of patients without bronchopulmonary infection was not statistically significant (82% and 81%, respectively, 1 year after transplantation). CONCLUSION: Opportunistic bronchopulmonary infections are common after lung transplantation. The most common pathogen is CMV, which causes diverse chest radiographic patterns. Opportunistic bronchopulmonary infections do not adversely affect overall mortality.

Multiple pulmonary nodules in AIDS: usefulness of CT in distinguishing among potential causes.
PURPOSE: To determine whether the computed tomographic (CT) appearances of multiple pulmonary nodules in patients with acquired immunodeficiency syndrome (AIDS) can help differentiate the potential infectious and neoplastic causes. MATERIALS AND METHODS: The thoracic CT scans obtained in 60 patients with AIDS and multiple pulmonary nodules were reviewed retrospectively by two thoracic radiologists who were blinded to clinical and pathologic data. The scans were evaluated for nodule size, distribution, and morphologic characteristics. CT findings were correlated with final diagnoses. RESULTS: Thirty-six (84%) of 43 patients with opportunistic infection had a predominance of nodules smaller than 1 cm in diameter, whereas 14 (82%) of 17 patients with a neoplasm had a predominance of nodules larger than 1 cm (P <.001). Of the 43 patients with opportunistic infection, 28 (65%) had a centrilobular distribution of nodules; only one (6%) of 17 patients with a neoplasm had this distribution (P <.001). Seven (88%) of eight patients with a peribronchovascular distribution had Kaposi sarcoma (P <.001). CONCLUSION: In patients with AIDS who have multiple pulmonary nodules at CT, nodule size and distribution are useful in the differentiation of potential causes. Nodules smaller than 1 cm, especially those with a centrilobular distribution, are typically infectious. Nodules larger than 1 cm are often neoplastic. A peribronchovascular distribution is suggestive of Kaposi sarcoma.

Complications (excluding hyperinflation) involving the native lung after single-lung transplantation: incidence, radiologic features, and clinical importance.
PURPOSE: To determine the incidence, importance, and radiologic features of native lung complications after single-lung transplantation. MATERIALS AND METHODS: Seventeen (15%) of 111 single-lung transplant recipients developed native lung complications (excluding hyperinflation) 0-58 months (mean, 17 months) after transplantation. Complaints at presentation, culture or histopathologic results, diagnostic or therapeutic procedures, and outcome were recorded. Chest radiographs (n = 17) and computed tomographic (CT) scans (n = 8) obtained at time of diagnosis were reviewed. Serial radiographs were assessed for disease progression or improvement. RESULTS: The most common complications were infection (n = 10), caused by bacteria (n = 4), fungi (n = 4), or mycobacteria (n = 2), typically manifested as lobar or segmental opacities on chest radiographs or CT scans. Lung cancer manifested as a solitary well-circumscribed nodule (n = 1), multiple nodules (n = 1), or a hilar mass (n = 1). Five (29%) of 17 patients died of native lung complications. Seven patients underwent mediastinoscopy (n = 3), lobectomy (n = 2), thoracoscopic wedge resection (n = 2), tube thoracostomy (n = 2), or pneumonectomy (n = 1) for diagnosis or treatment. CONCLUSION: Native lung complications occurred in 17 (15%) single-lung transplant recipients, were most commonly due to infection or lung cancer, and caused serious morbidity or mortality in 12 (71%) of 17 patients affected.

Lymphangiomyomatosis recurrence in the allograft after single-lung transplantation.
The evolution of lung transplantation has offered an additional treatment option for patients with a variety of end-stage lung diseases, including some with systemic disorders. Lymphangiomyomatosis (LAM) is a multisystem disease of premenopausal women. The lung is the most frequently involved vital organ, and respiratory failure is the most common case of death. A small number of patients with LAM have undergone lung transplantation. This report describes a case of recurrent LAM in the allograft after single lung transplantation and discusses the implications of this finding.

Bronchoalveolar lavage fluid angiotensin-converting enzyme in interstitial lung diseases.
In this study we evaluated the disease specificity of bronchoalveolar lavage fluid angiotensin-converting enzyme (BALF-ACE), its correlation with cellular constituents of bronchoalveolar lavage fluid (BALF), and for sarcoidosis, with other proposed markers of disease activity. Furthermore, the question of the clinical value of BALF-ACE determinations in in interstitial lung diseases or any of its subgroups was addressed. The study population consisted of 222 patients, 69 with biopsy proven sarcoidosis, 3 with hypersensitivity pneumonitis, 4 with acute histoplasmosis, 27 with idiopathic pulmonary fibrosis (IPF), 4 with rheumatoid arthritis-related interstitial fibrosis, 9 with pulmonary drug toxicity, 16 with pulmonary malignancies, 26 with other parenchymal lung disease entities, and 30 in whom the final diagnosis remained indeterminate. Elevated BALF-ACE concentrations were seen in all diagnostic categories. In sarcoidosis BALF-ACE levels correlated well with lavage lymphocyte counts (r = 0.49; p less than 0.0001), in contrast to IPF where they correlated well with lavage neutrophil counts (r = 0.51; p less than 0.007). The correlation of BALF-ACE and serum-ACE was significant. In sarcoidosis the mean BALF-ACE level was lower for patients with Stage-I chest roentgenographic patterns (0.664 U/L), compared to those with Stage II (1.112 U/L) and Stage III (1.083 U/L). It was concluded that elevated BALF-ACE levels are not specific for sarcoidosis. The correlations of BALF-ACE levels with different cellular constituents of BALF suggest a different cellular origin of BALF-ACE. In sarcoidosis BALF-ACE levels correlate well with other proposed markers of disease activity and seem to reflect pulmonary activity better than serum ACE.(ABSTRACT TRUNCATED AT 250 WORDS)
