72 cases of diffuse interstitial lung diseases were observed from 1969 to 1976. Specimens removed from 47 patients were subjected to the whole spectrum of reactions. According to variation of both elastin and collagen, the following groups were outlined: group A: mycobacteriosis, farmer's lung, sarcoidosis and silicosis; group B: chronic eosinophilic pneumonia, lymphocytic interstitial pneumonia, post-tuberculous pulmonary fibrosis, and group C: X-ray pneumopathy, desquamative interstitial pneumonia, sclerodermic pneumopathy and chronic pulmonary fibrosis (primary chronic fibroadenomyosis). Each of these groups presents a close relationship between histochemical, radiological, clinical and functional findings.

An extensive range of investigations were used in a comparative study of immune reactivity in the tuberculous pulmonary pathology, as well as in sarcoidosis, pneumonia and cancer of the lungs. T and B lymphocyte populations were followed, indexes of leucocyte migration, induced lymphoblastogenesis to phytohaemagglutinin, and the serum levels of immunoglobulins. Also the intensity of the hypersensitivity to tuberculin was investigated, to allergens extracted from staphylococcus and streptococcus strains, as well as against organ antigens (pulmonary tissues). Differences were evidenced, of immunologic reactivity in various nosologic entities investigated. The dynamic follow-up of some of the cases has demonstrated that the immunological reactivity varies in parallelly with severity of cases, deficiences being corrected by adequate therapy. The immunologic status may be considered a criterium for a rational pathogenetic treatment, for assessing the efficiency of such a treatment, as well as for the differential diagnosis of pulmonary diseases.

Between April 1976 and February 1980, serum levels of angiotensin-converting enzyme were determined in 61 cases of sarcoidosis at different stages of evolution. Cases were divided in three groups on the basis of social determinations done every 3-6 months. In the group with 46 active cases the increase in mean value of the enzyme is statistically significant compared to the control group; 30 of these (65.2%) had values higher than + 2DS. In the second group with 24 cases of non-progressive or inactive sarcoidosis the mean value was slightly higher than the normal mean value, without being statistically significant; 21 patients (87.5%) showed normal values: in the third group with 19 patients who had been treated with corticosteroids, mean value was equal to normal values; after 12 months treatment values were normal in 17 cases (89.5%). In the control group of 80 patients with a variety of pulmonary diseases other than sarcoidosis (pulmonary tuberculosis, pneumonia, pulmonary thromboembolism and primary lung cancer) only 9 cases presented values higher than the normal + 2SD (11.2% false positive). Serial determination of angiotensin-converting enzyme is a useful diagnostic parameter in sarcoidosis; especially in evaluating progression of the disease as well as the efficacy of corticosteroid treatment.

The pulmonary manifestations of sarcoidosis are varied. This report describes a patient with rapidly progressive pulmonary sarcoidosis which had several unusual features and presented with acute pneumonia with air bronchograms on chest radiographs. Gallium-67 scanning and serum angiotensin-converting enzyme estimations aided in the diagnosis and in determining the response to steroid therapy.

Routine preoperative testing on patients undergoing elective and emergency surgery has identified life-threatening illnesses unknown to the patient. Over a six-year period, 34 patients were found to have such medical problems, including cancer, diabetes, heart disease, tuberculosis, pneumonia, Paget's disease, and sarcoid.

The chest roentgenograms are described in eight patients with sarcoidosis who demonstrated a peripheral distribution of pulmonary infiltrates quite similar in appearance to that classically observed in eosinophilic pneumonia. The presence of mediastinal/hilar lymph node enlargement (eight patients), a nodular component to the infiltrate (four patients), an often asymptomatic presentation (four patients), and absence of blood eosinophilia (eight patients) should suggest the correct diagnosis.

We report here an elderly woman who started vague complaints around the age of 50, was proved to be a sarcoidosis by negative skin reaction with purified protein derivative, bilateral hilar lymphadenopathy, and sarcoid lesions in biopsied liver and lymph nodes, and died of cardiac insufficiency after 15 years of the illness. Necropsy revealed a huge tumor-like left atrial thrombus with nonspecific fibrous lesions throughout the myocardium, a pulmonary hamartoma, pneumonia, liver cell necrosis, and cholecystopathy. To our knowledge, this may be the first case of myocardial sarcoidosis associated with this kind of atrial thrombus, although the sarcoidosis and thrombus may have occurred independently.

Rapidly progressive pulmonary distress occurs as a secondary complication in immunocompromised pediatric patients. These patients usually develop a pattern of diffuse alveolar and/or interstitial infiltrates on chest x-ray and pursue a rapidly downhill course despite intensive respiratory support with the use of multiple and varied antimicrobial regimens. These patients are subjected to diagnostic open lung biopsies to establish a diagnosis. The diagnostic value of open lung biopsy and its current impact on therapy is not clearly established. This retrospective study attempts to determine the impact of open lung biopsy on diagnosis and therapeutic outcome. Between November, 1974, and October, 1982, 40 diagnostic open lung biopsies were performed on immunocompromised patients with clinically progressive respiratory disease. Adequate follow-up for complete evaluation was possible in 34 of these patients. Most of these patients had hematologic malignancies and all were on chemotherapeutic drugs at time of open lung biopsy. Open lung biopsy was considered helpful, ie, resulted in a change in antimicrobial therapy or substantiated preoperative therapy, in 17 of our 34 patients (50%). A "treatable" condition, amenable to antimicrobial therapy, was diagnosed in 16 of our patients (47%). Pneumocystis carinii pneumonitis (PCP) was the most common diagnosis in 11 (69%) of our "treatable" patients. The remaining five "treatable" patients had sarcoidosis (1), histiocytosis X (1), bacterial pneumonitis (1) and fungal pneumonitis (2). No diagnosis was achieved by open lung biopsy in ten (30%) of our patients. There were two complications attributable to open lung biopsy (6%), including one death. All PCP patients treated with trimethoprim sulfamethoxazole (T/S) survived.(ABSTRACT TRUNCATED AT 250 WORDS)

A 49-year-old man with fever, malaise, weight loss, and pneumonia developed cutaneous nodules and neurologic symptoms. Skin biopsy studies revealed granulomatous inflammation consistent with a sarcoid reaction, and mild granulomatous changes were noted on biopsy specimens of liver and bone marrow. A lymph node biopsy was unremarkable. Neurologic deterioration prompted an extensive workup that revealed an intracranial mass. A brain biopsy study revealed malignant lymphoma, large cell type. Autopsy study confirmed the diagnosis and showed no evidence of granulomatous infiltrates. The cutaneous granulomas represent a nonspecific immune response possibly related to the underlying lymphoma. The relationship between sarcoidosis and sarcoid reactions and lymphoma is discussed.

M. pneumoniae is a common cause of pneumonia. The diagnosis is suspected when the patient presents with symptoms suggesting primary atypical pneumonia including cough, fever, chills, headache, and malaise in association with a segmental or subsegmental pulmonary infiltrate(s), the white blood cell count is normal or only slightly elevated, and the Gram stain of the sputum (if any can be obtained) reveals polymorphonuclear leukocytes and few bacteria. The diagnosis is more difficult when the patient presents with symptoms not suggestive of pneumonia including lethargy, dyspnea, and a 1- to 4-week history of shortness of breath without cough or fever in association with diffuse reticulonodular or interstitial pulmonary infiltrates. The disease in the previously healthy host is usually benign and self-limiting. However, the course is shortened by the administration of tetracycline derivatives or erythromycin. M. pneumoniae pneumonia can occur in association with other diseases including sickle cell anemia, sarcoidosis, systemic lupus erythematosus, Hodgkin's disease, and various other immunodeficiency states. In these patients mycoplasma pneumonia can be very serious. Although there is no pathognomonic clinical or radiographic presentation, careful consideration of epidemiologic, clinical, laboratory, and radiographic data are usually sufficient to suggest the diagnosis in most patients.
