A 66-year-old male presented to our hospital in January 1990 with chief complaints of hemoptysis and cough. These symptoms had developed 10 months previously and had gradually increased. Fine crepitations were audible over the right lower lung field. There were no results suggesting an inflammatory process such as leucocytosis, elevation of ESR or positive CRP reaction. Chest X-ray film on the first visit showed fine nodular shadows in the right lower lung field, and chest CT revealed fine nodular shadows and mild dilatation of the right lower lobe bronchus. Transbronchial lung biopsy specimens showed granulomas with multinucleated giant cells, alveolitis and Masson bodies. The open lung biopsy specimens showed numerous macrophages and foreign body giant cells, and extensive organizing exudates in the bronchioles and alveolar spaces. Proliferation of smooth muscle and fibrosis around the dilated bronchioles were also seen. Thus, this patient demonstrated BOOP pattern, with granulomas and foreign body giant cells. His hemoptysis appeared to have resulted from inflammation of dilated bronchioles. His symptoms and abnormal shadows on chest X-ray improved without any therapy after admission. After treatment with corticosteroid, the diffuse fine nodular shadows disappeared. There has been no recurrence of symptoms to date, although this patient has continued living in the same environment as prior to admission. BAL findings during his prolonged follow-up revealed decrease in lymphocytes and elevation of CD4/CD8 ratio. Although the presence of granulomas suggests the possibility of an allergic reaction, no antigenic material could be identified in this case.(ABSTRACT TRUNCATED AT 250 WORDS)

A 32-year-old female complained of productive cough and bloody sputum. Infiltrative shadows and cavitary lesions with thick and irregular wall in the bilateral lung fields and the swelling of mediastinal lymph nodes were pointed out on the chest radiography. Physical examination revealed no abnormal findings. ESR and the level of the serum angiotensin converting enzyme were slightly elevated. In the BAL (broncho-alveolar lavage) fluid, lymphocytes and neutrophils increased, and the OKT4/OKT8 ratio of the lymphocytes was 0.81. Open lung biopsy revealed numerous sarcoid granulomas with granulomatous vasculitis in the cavity wall, surrounding infiltrative lesions and hilar lymph nodes. After the administration of prednisolone, the infiltrative shadows and the cavitary lesions showed marked improvement. It was concluded that open lung biopsy is necessary for the diagnosis of NSG because the differential diagnosis between NSG and limited form of Wegener's granulomatosis is extremely difficult from such a small lung specimen as that obtained by trans-bronchial lung biopsy.

Bronchiolitis obliterans organizing pneumonia (BOOP) is a pathologic finding common to various injuries to the lung of either definite or idiopathic etiology. Since the presentation of patients with idiopathic BOOP varies, we studied 16 patients with BOOP on pulmonary histology to define more distinct and homogeneous clinical and imaging profiles of idiopathic BOOP. We distinguished three groups of patients: group 1 (n = 4), with multiple patchy migratory pulmonary involvement of the pneumonia type. Their clinical course was subacute, with cough, fever, weight loss, mild dyspnea, and increased ESR. Chest x-ray film and CT scan showed multiple alveolar opacities. All patients completely recovered with corticosteroid therapy but relapsed when therapy was stopped too rapidly. Group 2 (n = 5) had solitary pulmonary involvement of the pneumonia type occurring in a similar clinical context. Since carcinoma was suspected, they underwent surgical excision of the pneumonic area and recovered without relapse. Group 3 patients (n = 7) presented with diffuse pulmonary involvement of the interstitial lung disease type. They had more progressive onset of more severe dyspnea, crackles heard over all lung surfaces, and interstitial opacities with or without alveolar opacities on chest imaging. Improvement with corticosteroid therapy was obtained in only three patients. In all three groups, lung function test results showed a restrictive pattern. The obstructive pattern characteristic of pure bronchiolitis obliterans was found in none. BAL showed a mixed pattern (increase of both lymphocytes and polymorphonuclear cells) in the patients of the first two groups. Thus, we distinguished three characteristic clinical and imaging profiles in patients with idiopathic BOOP: multiple patchy pneumonia, solitary pneumonia, and diffuse interstitial lung disease. These profiles are so different that they should be distinguished in clinical studies of idiopathic BOOP.

Dysphagia is a rare manifestation of sarcoidosis. It is more commonly the result of esophageal compression by enlarged mediastinal lymph nodes rather than direct esophageal involvement and rarely secondary to neurosarcoidosis and oropharyngeal dysphagia. We report a 54 year old female presenting with a six month history of worsening dysphagia. She denied respiratory symptoms. Physical exam was normal. ESR was 61 mm/hr. Serum ACE level was 65 mcg/L. Chest X-ray was normal. Esophagram revealed a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. Swallow videofluorography showed a decreased retraction of the base of the tongue, limited laryngeal elevation, and a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. EGD showed a normal opening of the upper esophageal sphincter and the cricopharyngeus appeared normal. Proximal esophageal biopsies were normal. Brain MRI with gadolinium was normal. Lumbar puncture was performed. CSF showed a moderate pleocytosis, a WBC count of 19 with 97% lymphocytes, an elevated total protein level of 85 mg/dl (15-60). Neck CT scan showed no oropharyngeal tissue thickening or infiltration, no masses or enlarged lymph nodes. Chest CT scan showed enlarged intrathoracic lymph nodes and no esophageal compression. Bronchoscopy showed the vocal cords to be intact, and the CD4/CD8 ratio in BAL was 5.3. Subcarinal lymph node EBUS biopsy revealed non caseating granulomas. The patient was started on IV methylprednisolone. Three days later, the swallow videofluorography showed a near complete response to steroids. The patient tolerated regular consistency diet with thin liquids, and she was discharged on a slow taper of prednisone over a period of three months. A unique case of isolated dysphagia unmasking bulbar neurosarcoidosis and pulmonary sarcoidosis is herein reported.
