We present a case of thoracic splenosis in a 42-yr-old man with a medical history of abdominal surgery for a penetration injury with an iron bar of the left abdomen and back. He had been in good condition, but a chest radiograph taken during a regular checkup showed a multinodular left pleura-based mass. Computed tomography (CT) showed that the mass was well-enhanced and homogeneous, indicating a sclerosing hemangioma. Following its removal by video-assisted thoracoscopic surgery, the mass appeared similar to a hemangioma, with marked adhesion to the left side diaphragmatic pleura and lung parenchyma. Frozen section showed that the lesion was a solid mass consisted with abundant lymphoid cells, suggesting a low grade lymphoma. On permanent section, however, the mass was found to be composed of white pulp, red pulp, a thick capsule and trabeculae and was diagnosed as ectopic splenic tissue, or thoracic splenosis. Review of the patient's history and chest CT at admission revealed that the patient had undergone a splenectomy for the penetration injury 20 yr previously.

Mediastinal tuberculous lymphadenitis is rare in adults, and it is even rarer for dysphagia to be the presenting symptom of mediastinal tuberculous lymphadenitis. Mediastinal tuberculous lymphadenitis with esophageal symptoms has been presented as esophageal ulceration, mucosal or submucosal mass with ulceration, fistula or sinus formation, extrinsic compression, or displacement of the esophagus. An exaggerated form of extrinsic compression may be presented as a submucosal tumor, radiologically or endoscopically. A barium esophagography of a 34 year-old woman with painful dysphagia revealed a large submucosal tumor-like mass on the mid-esophagus. The symptom was spontaneously improved over a 3-week period together with reduction of the mass size. A computed tomography of the chest disclosed an enlarged subcarinal lymph node and histologic examination of the specimen obtained by thoracoscopic biopsy brought about a diagnosis of tuberculosis. We herein report a case of mediastinal tuberculosis with unusual manifestations.

BACKGROUNDAmyloidosis is a collection of diseases in which different proteins are deposited. Amyloid deposits occur in systemic and organ-limited forms. In both systemic and localized forms of the disease, lung can be involved. The aim of this study was to explore the different respiratory manifestations of amyloidosis.

METHODSChest radiology, clinical presentations, bronchoscopic/laryngoscopic findings and lung function data of 59 patients with amyloidosis involving respiratory tract collected during January 1986 to March 2005, were analysed.

RESULTSOf the 16 cases with localized respiratory tract amyloidosis, 8 had the lesions in the trachea and the bronchi, 2 in the larynx and the trachea, 5 in the larynx and/or the pharynx, and 1 in the lung parenchyma. Of 43 systemic amyloidosis with respiratory tract involvement, 3 had the lesions in bronchi, 13 in lung parenchyma, 33 in pleura, 8 in mediastina, 1 in nose and 1 in pharynx. Chest X-rays were normal in most cases of tracheobronchial amyloidosis. CT, unlike chest X-rays, showed irregular luminal narrowing, airway wall thickening with calcifications and soft tissue shadows in airway lumen. Localized lung parenchymal amyloidosis presented as multiple nodules. Multiple nodular opacities, patch shadows and reticular opacities were the main radiological findings in systemic amyloidosis with lung parenchymal involvement. In pleural amyloidosis, pleural effusions and pleural thickening were detected. Mediastinal and/or hilar adenopathy were also a form of lung involvement in systemic amyloidosis. The major bronchoscopic findings of tracheobronchial amyloidosis were narrowing of airway lumen, while nodular, 'tumour like' or 'bubble like' masses, with missing or vague cartilaginous rings, were detected in about half of the patients.

CONCLUSIONSLocalized respiratory tract amyloidosis mostly affects the trachea and the bronchi. Chest X-rays are not sensitive to detect these lesions. Systemic amyloidosis often involves lung parenchyma and the pleura. Open lung biopsy or pleural biopsy should be performed for the diagnosis.

OBJECTIVEDiffuse lung disease comprises a large, heterogeneous group of pulmonary interstitial and parenchymal disease. It is therefore difficult to some extent to make etiologic diagnosis. Little information on clinical spectrum and diagnostic evaluation of pediatric diffuse lung disease is available in our country. The purpose of this study was to explore the causes of and diagnostic approach to diffuse lung disease in children.

METHODSTwenty-eight children with diffuse lung disease aged 2 months to 14 years were studied retrospectively. Their history, physical examination, radiographic findings, final diagnosis and diagnostic processes were reviewed.

RESULTSConfirmed diagnosis was established in 25 cases and suggestive diagnosis in 3 cases. Confirmed diagnoses included: mycoplasma pneumonia in 1 case, Chlamydia trachomatis pneumonia in 2 cases, Epstein-Barr virus pneumonia in 1, CMV pneumonia in 2, hematogenous disseminated pulmonary tuberculosis in 3, pulmonary cryptococcosis in 1, invasive pulmonary aspergillosis in 2, Staphylococcus aureus sepsis in 1, diffuse bronchiectasis in 2, idiopathic pulmonary hemosiderosis in 1, idiopathic pulmonary fibrosis in 1, extrinsic allergic alveolitis in 1, HIV-related lymphocytic interstitial pneumonitis in 1, Wegner's granulomatosis in 1, Langerhan's cell histiocytosis in 2, and lymphoma in 3. Suggestive diagnoses included Nocardia pneumonia in 1, Pneumocystis carinii pneumonia in 1, and juvenile rheumatoid arthritis-associated pulmonary fibrosis in 1. The diagnostic directions of 26 patients were conducted by radiographic features. In 17 of 26 cases, the diagnostic range was confined by history. The diagnosis of 14 cases was made by noninvasive tests including antibody detection, bacterial culture, those of 8 cases by examination of biopsy material, and those of 2 cases by autopsy.

CONCLUSIONSThe causes of pediatric diffuse lung disease included pulmonary infectious disease, idiopathic pulmonary disease and pulmonary lesion associated with systemic diseases. The diagnosis may be made by radiography, history, physical examination, noninvasive tests in most cases, while in some cases invasive procedures were necessary.
