Interstitial pneumonitis includes more than a hundred diseases in which alveolitis is the main manifestation of the affected lung. Symptoms such as dry cough and exertional dyspnea, fine crackles on chest auscultation, interstitial infiltrates on chest X-ray films and CT scans, respiratory function tests, and Ga-67 scintigraphy have been used for the diagnosis and the evaluation of disease activity. However, the poor prognosis of some types of interstitial pneumonitis has not been improved. We discovered a high molecular weight mucin-like antigen, designated KL-6, which is also known as MUC1. The serum level of KL-6/MUC1 was elevated in 70-100% of patients with interstitial pneumonitis, such as pulmonary fibrosis (either idiopathic or related to collagen-vascular disorders), hypersensitivity pneumonitis, sarcoidosis, and radiation pneumonitis. The levels were significantly higher in patients with active disease than in those with inactive disease. In contrast, patients with noninterstitial lung disease did not show a significant elevation of KL-6/MUC1. Furthermore, the serum KL-6/MUC1 level was found to be an early predictive marker of the therapeutic effect of high-dose corticosteroids in patients with rapidly progressing idiopathic pulmonary fibrosis. These results indicate that KL-6/MUC1 may be a useful serum marker for the diagnosis and monitoring of patients with interstitial pneumonitis.

We report a case with rheumatoid arthritis and hypersensitivity pneumonitis. A 66-year-old female was admitted to our hospital because of fever, cough, and progressive dyspnea on October 10, 1997. She had a history of rheumatoid arthritis from 1987 and was treated with cyclophosphamide when she developed pulmonary symptoms in September 1997. On admission arthritis was subsided. Fine crackles on ausculation of lung, hypoxia, ground-glass appearance on chest X-ray were detected. The computed tomography of the chest disclosed diffuse interstitial shadow with patchy destruction of alveolar structures. Bronchoalveolar lavage demonstrated an increase in lymphocytes with predominance of suppressor-cytotoxic T cell subset (CD 8+). The histopathological examination of transbronchial lung biopsy showed interstitial inflammation with marked predominance of lymphocyte with intraalveolar exudate. Her condition got better and she discharged without definitive diagnosis and treatment for her respiratory symptoms. Eight hours after she went back home, she suddenly presented high fever and cough and gradually developed dyspnea. She was readmitted 5 days after the previous discharge. Although no specific precipitin antibody against various microorganisms was detected in her sera, the diagnosis of hypersensitivity pneumonitis was made. Thirty mg per day of prednisolone was resolved her symptoms promptly. There was no reported case with hypersensitivity pneumonitis and rheumatoid arthritis of other collagen diseases. The clinical course that arthritis and pulmonary symptoms appeared alternatively is of considerable interest to investigate for the pathogenesis of these two immune disorders.

The purpose of this study was to describe the clinical features at onset and outcome and the diagnostic approach in subjects with bronchiolitis obliterans-organizing pneumonia (BOOP). Over a 7-year period we observed 78 cases of biopsy-proven bronchiolitis obliterans-organizing pneumonia, in which well documented clinical and radiographic data were available. The final diagnosis of BOOP was validated when patients presented: (i) negative microbiological analysis on BAL fluid; (ii) a well documented improvement either spontaneous, or after steroid treatment or (iii) cases with progressive respiratory failure and increasing radiographic shadows, an open lung biopsy or autopsy that excluded other entities. There were 42 males and 36 females; the mean age was 61+/-12 years (range 12-85 years). Forty-two (54%) patients were current smokers, 25 (32%) had never smoked and 11 (14%) were ex-smokers. The clinical pattern at presentation of BOOP was more frequently similar to classical acute or sub-acute infectious pneumonia. Fever (63%), dyspnoea (58%) and dry cough (53%) were the typical symptoms on admission. A flu-like syndrome preceeding BOOP was observed in 21 cases (27%). Inspiratory crackles (78%) were the most typical finding at physical examination. However, 13% of the patients were asymptomatic and an abnormal chest X-ray film was the reason for seeking medical attention. Radiographically the most frequent pattern of BOOP was a unilateral consolidation (44%) with lower field predominance. A migratory behaviour was present in 22% of the cases. High-resolution computed tomographic (HR-CT) scan when performed, was more sensitive in detecting ground glass infiltrates, sub-pleural or peri-bronchovascular distribution or the presence of nodules or cavitation. Most patients (68%) were classified as having idiopathic BOOP. However, the same clinical-roentgenological pattern was observed in patients after radiotherapy for ductal breast carcinoma (6%), in collagen-vascular diseases (6%), related to drugs (9%), to infections serologically documented (4%), and to graft vs. host disease (4%). Four patients (all of whom had idiopathic BOOP) presented a rapid progressive respiratory failure needing mechanical ventilation. In another two cases respiratory failure appeared after a long period during which patients experienced exertional dyspnoea and low grade fever. BAL profile was characterized by lymphocytosis with a reduction of the CD4/CD8 ratio, associated with a slight increase of neutrophils and eosinophils and scattered mast cells. However in two cases we had an increased CD4/CD8 ratio and in one case the presence of a significant 12% of polyclonal B cells. In a few cases atypical (cytokeratin-positive cells) epithelial cells were detected: these cells were constantly present in the BAL fluid of patients with rapidly progressive respiratory failure. From the diagnostic point of view this series documents that transbronchial lung biopsy (coupled with BAL) can be the first diagnostic step. However, therapy can be started on the basis of BAL data (when a characteristic morphological and phenotypical profile is evident) in cases in which the clinical presentation is suggestive and a biopsy cannot be made. Most patients showed a rapid and good response to steroid therapy. However, three patients died (4%) in spite of steroid therapy (two cases) and steroid and cyclophosphamide therapy (one case). In conclusion, although clinical findings, chest X-ray film and CT Scan findings usually suggest the diagnosis a definite confirmation requires transbronchial lung biopsy and BAL and, less frequently, open lung biopsy.

A 73-year-old woman had a 4-year history of lung fibrosis from collagen vascular disease. She presented with a complaint of dry cough. A chest radiograph showed a 2-cm solitary pulmonary nodule with a small cavity in the right lower lobe. Preoperatively, we performed computed tomography of the chest and measured tumor markers. Video-assisted thoracotomy was performed because we could not rule out lung cancer. Pathologic analysis confirmed the presence of a granuloma with Dirofilaria immitis. In Japan, the incidence of human dirofilariasis has steadily increased and must be considered in the workup of cavitary pulmonary nodules.

A 71-year-old male is presented as ever the oldest patient of tetralogy of Fallot who underwent successful radical surgery. Heart murmur was pointed out at the age of 10 years. The patient consulted us because of dyspnea and cough, and was noted to have cyanosis and clubbing fingers. Polycythemia was also detected by hemoglobin of 20.8 g/dl and hematocrit of 58.4%, and a low PaO2 of 48.5 mmHg at room temperature was pointed out. Preoperative echocardiography and cardiac catheterization indicated a ventricular septal defect, overriding of the aorta, and right ventricular outflow tract stenosis with a pressure gradient of 115 mmHg between the right ventricle and the main pulmonary artery. Under cardiopulmonary bypass, the ventricular septal defect was closed with a dacron patch and the right ventricular outflow tract was enlarged by a patch of collagen-coated vascular graft with a commissurotomy of the pulmonary valve. Postoperatively, cyanosis disappeared and the pressure gradient was decreased to 26 mmHg.

We report two cases of localized benign pleural mesothelioma with different clinical features. Neuropsychiatric symptoms, including coma, hemiplegia, seizures and misbehavior predominated in the first case, associated with hypoglycemia. The symptoms in the second case were essentially respiratory (cough, dyspnea, and chest pain). Treatment consisted in thoracotomy and complete surgical resection. Histopathology revealed fusiform cells and collagen stroma. These two cases illustrate the diversity of clinical expression of benign localized pleural mesothelioma and confirm their complete resolution after surgical treatment.

A 67-year-old man with a four-year history of mixed connective tissue disease (MCTD) associated with interstitial pneumonia was admitted to our hospital with a complaint of dyspnea and moist cough. Because the interstitial pneumonia was exacerbated, he was given high-dose steroid treatment (pulse therapy and sequential oral treatment of PSL 50 mg/day). After treatment his general condition showed some improvement, but then he suddenly died of acute respiratory failure. Autopsy disclosed fat emboli in the lungs, kidneys, liver and myocardium. The fat embolism may have been a consequence of the steroid treatment. Fat embolism should be taken into account as one of the causes of the acute respiratory failure in collagen vascular disease patients receiving steroid treatment.

A 56-year-old woman was initially seen in March 1998 with a complaint of back pain. Her thyroid gland was swollen and the level of TSH was elevated at 10 microU/ml. Chronic thyroiditis with hypothyroidism was diagnosed. Negative reactions were obtained for both anti-thyroglobulin and anti-thyroid peroxidase antibodies. Daily treatment with thyroxine 50 mg was started. A cough developed in August 1998, and her chest radiographs revealed multiple bilateral consolidation shadows. A transbronchial lung biopsy specimen demonstrated mononuclear cells infiltration in the alveolar septa with fibrosis, consistent with nonspecific interstitial pneumonia (NSIP). There were no findings clinically or serologically suggestive of collagen-vascular diseases. Ultimately interstitial pneumonia compatible with the NSIP pattern in association with chronic thyroiditis was diagnosed. Oral prednisolone (30 mg/day) and azathioprine (50 mg/day) administration was initiated. The cough and the shadows on the chest radiographs improved. However, one year after completion of the treatment, interstitial pneumonia recurred. Retreatment with prednisolone and azathioprine has resulted in its improvement.

A 73-year-old African American female presented to our clinic with painful lower extremity lesions of 2 weeks duration. She was in her usual state of health until 3 months prior to presentation when she reported symptoms of fatigue and weakness. She also noticed an enlarging mass on the left side of her neck. She denied fevers, chills, night sweats or cough. Her symptoms were unresponsive to a course of oral dicloxacillin. The neck mass enlarged over 8 weeks and she was referred to our institution for evaluation. CT scan of the neck showed an enlarged lymph node. Ten days prior to her presentation in dermatology, a fine needle aspirate of the enlarging lymph node revealed necrotizing granulomas. Tissue was sent for routine mycobacterial and fungal cultures. Routine blood work, chest radiograph, and a tuberculin skin test were also performed. At the time of her dermatology visit she described the development of multiple new painful, non-pruritic lesions, bilaterally on the lower extremities. She also reported a red crusted area that appeared at the site of her tuberculin test that was placed subsequent to the development of her lower extremity lesions. Her past medical history was significant for Parkinson's disease, hypothyroidism and hypertension. Her current medications included l-thyroxine, estrogen and diltiazem. Her travel history was only remarkable for a trip to Jamaica the previous spring. She was born and raised in Haiti. She reported a history of a positive tuberculin skin test 20 years ago, but received no therapy. Physical examination revealed a 2 x 3 centimeter firm, nontender left lateral neck mass (Fig. 1). Her right forearm revealed an erythematous, ulcerated, indurated plaque 1.5 cm in diameter (Fig. 2.). Her lower extremities revealed tender 0.5 to 1 cm erythematous nodules below the knees bilaterally (Fig. 3). A punch biopsy of a lower extremity nodule revealed a mild pervisacular dermal infiltrate. Within the subcutaneous tissue there was septal widening. There was also a lymphohistiocytic infiltrate with a slight admixture of neutrophils within the septa of the fat lobules. There was no evidence of necrotizing vasculitis or collagen necrosis. An acid-fast stain was not performed. The histologic findings were consistent with a diagnosis of erythema nodosum. Her laboratory evaluation including CBC, electrolytes, thyroid studies, angiotensin converting enzyme level and chest radiograph were normal. Approximately 1 week after her dermatological evaluation, the fine-needle aspirate culture grew Mycobacterium tuberculosis. A diagnosis of tuberculous lymphadenitis associated with erythema nodosum was confirmed. The patient was started on quadruple therapy of isoniazid, rifampin, ethambutol and pyrazinamide. Her lower limb skins lesions rapidly resolved over the subsequent month and her neck mass also diminished in size. She completed 6 months of antituberculous therapy with complete resolution of her lymphadenopathy.

Desmoplastic mesothelioma is a rare subtype of diffuse malignant mesothelioma, and is often difficult to distinguish from reactive pleural fibrosis because of associated extensive collagen fibrosis. An 82-year-old woman with a severe cough was revealed to have pleural effusion and diffuse pleural thickening on the right side. Antibiotics were ineffective, and a compression fracture of the ninth and tenth thoracic vertebral bodies was recognized on X-ray. Autopsy revealed a diffuse pleural thickening with hyalinized collagen tissue in the central part of the pleura. However, the peripheral part of the fibrous tissue was composed of spindle and polygonal cell proliferation that were immunohistochemically positive for antibodies against cytokeratin and vimentin. In addition, the ninth and tenth thoracic spines were infiltrated by similar cells. The condition was diagnosed as desmoplastic mesothelioma with bone metastases. Asbestos bodies were detected in the thickened pleura and fibrosed alveolar septa, and it was suggested retrospectively that the patient had been exposed to asbestos. Thus, autopsy analyses of fibrous pleurisy are necessary to detect a desmoplastic variant of mesothelioma of the pleura and its association with asbestos exposure.
