Objective To improve the knowledge of bone marrow tuberculosis by summarizing the risk factors, clinical features, diagnosis, therapeutic response and prognosis. Methods The medical records of 62 patients with bone marrow tuberculosis from January 2004 to December 2014 were retrospectively analyzed. Results The patients included 34 males and 28 females. Their age ranged from 15 to 80 years with a mean age of 45.3±35.7 years. Among them, 21 cases (33.9%) had one or more risk factors such as advanced kidney disease or liver disease, chronic respiratory disease, rheumatoid immune system disease and diabetes. No specific clinical features were found in patients with bone marrow tuberculosis, and the most common symptom was fever (98.4%). Blood routine examination revealed that variety of hematological abnormalities include leucopenia, thrombocytopenia, anemia or pancytopenia occurred in 59 patients (95.2%). Chest CT scan showed typical disseminated tuberculosis in 22 patients (36.1%), secondary pulmonary tuberculosis in 6 patients (9.8%), and atypical manifestations of tuberculosis in 26 patients (42.6%). The common patterns of abdomen abnormalities on ultrasonic testing or CT scan were hepatosplenomegaly. Bone marrow biopsy was performed in all the 62 patients, among them, the needle-aspirated bone marrow specimens showed granulomatous lesions in 53 patients (85.5%). The acid-fast staining of bone marrow smear was performed in a total of 57 patients, which was positive in 28 patients (49.1%). Twenty-five patients completed phone call follow-up, and 8 patients died from bone marrow tuberculosis and its complications. Conclusions Bone marrow tuberculosis is a rare manifestation of disseminated tuberculosis. The common symptom of this disease is pyrexia . The clinical presentations and laboratory examinations of this disease are nonspecific. Bone marrow biopsy is a major method for diagnosis. Part of patients with bone marrow tuberculosis lack of imaging proof for lung lesion. Therefore, we should heighten vigilance for bone marrow tuberculosis in patients with fever of unknown origin.
ObjectiveTo explore the clinical features, diagnosis, differential diagnosis, pathological characteristics, management and prognosis of airway hemangioma, and improve the level of the diagnosis and therapy.MethodsThe clinical data of a patient with airway hemangioma admitted to West China Hospital of Sichuan University were retrospectively analyzed. The related literatures were reviewed. Databases including PubMed, Ovid Medline, Embase, VIP, Wanfang and Chinese National Knowledge infrastructure were searched using the keywords as " Trachea” OR " Bronchus” AND " Hemangioma” from January 1976 to October 2016.ResultsThe patient was a 32-year-old male presented with hemoptysis and backache more than 10 days. His enhanced chest CT scan revealed thickening of the esophagus wall and narrowing of the lumen of esophagus. A wide range of vascular tumor like changes in the trachea and the two sides of bronchus were found by the fiberoptic bronchoscopy and gastroscope examination suggested esophageal varices. Although the patient had a wide range of airway lesions, the symptom of hemoptysis was relieved after the conservative treatment. The patient’s condition was stable until now. From January 1976 to October 2016, a total of 34 related articles were retrieved and 36 cases of airway hemangioma were reported. The etiology of the disease remains unknown. Recurrent hemoptysis was the common symptoms of airway hemangioma, and imaging changes lacking characteristics. Histopathological examination revealed dilated, thin-walled and different size of vascular or hyperplastic capillary and immunohistochemical staining was positive for vascular endothelial cell specific CD34 and Ⅷ factor.ConclusionsHemangioma is a common benign tumor of head and neck in infants and children. Hemangioma is very rarely occurred in trachea in adults. Clinical and imaging manifestations are not specific, and diagnosis relies on histopathological examination. Fiberoptic bronchoscopy and three dimensional reconstruction of thoracic vessels with CT play important roles in the whole process of diagnosis and treatment of airway hemangioma. It should be differentiated from lymphangioma. The prognosis of airway hemangioma is good.
