ABSTRACT
Little is known about longitudinal lung function variation in patients with pulmonary Langerhans' cell histiocytosis (LCH). The contribution of serial lung computed tomography (CT) to managing these patients has not been evaluated. This long-term retrospective study included 49 patients who were serially evaluated by lung CT and pulmonary function tests. The lung function variation was categorised as improvement or deterioration. The extent of the CT lesions was correlated with lung function. Lung function deteriorated in â¼60% of the patients. Forced expiratory volume in 1 s (FEV(1)) and diffusing capacity of the lung for carbon monoxide (D(L,CO)) were the parameters that most frequently deteriorated. A subgroup of patients experienced a dramatic decline in FEV(1) within 2 yrs of diagnosis. Airway obstruction was the major functional pattern observed. In a multivariate analysis, % predicted FEV(1)at diagnosis was the only factor associated with the incidence of airway obstruction. The increase in cystic lesions on the lung CTs was associated with impaired lung function but did not anticipate the decline in FEV(1) or D(L,CO). Serial lung function tests are essential for following patients with pulmonary LCH, who frequently develop airway obstruction. A lung CT at diagnosis is informative, but routine sequential CTs seem less useful. A prospective study is needed to characterise those patients with early progressive disease.

Synovial sarcoma (SS) is a rare tumor. It is characterized by various sites of occurrence but rarely involves the chest. The tumor may be wrongly diagnosed as benign due to its slow growth. Less than 10% of patients present with metastatic cancer. Endobronchial metastases are exceptional. Immunohistochemical examination and cytogenetic analysis allow to distinguish it from other mesenchymal tumors. The presence of SYT-SSX fusion transcript allows the diagnosis. Surgery is used for localized tumors that can be treated with radiation therapy while chemiotherapy is used for metastatic tumors. The average rate of locoregional or metastatic recurrence two years after SS is 50%. We report the case of a 28-year old patient with metastatic SS characterized by its uncommon metastatic site. He presented with endobronchial metastasis revealing his disease, that had evolved for more than 2 years. The SS is life-threatening due to its slow and insidious growth. Prognosis is guarded. This study aimed to emphasize this atypical site for metastatic synovial sarcoma as well as to insist on the role of early diagnosis and treatment.

Endobronchial aspergilloma and intracavitary pulmonary aspergilloma may clinically and radiologically mimic a bronchial neoplasia, hence the importance of systematically searching for an association. A confirmed association completely changes the prognosis as well as the therapeutic approach. We here report two cases with two different forms of pulmonary aspergilloma associated with bronchial carcinoma.

BACKGROUND: Breast tuberculosis is an uncommon disease even in countries where the incidence of tuberculosis is high. CASE REPORT: This is a case series concerning 4 postmenopausal breast tuberculosis cases encountered in Moulay Youssef Hospital between January 2007 and December 2010. Breast tuberculosis represents 0.25% of all hospitalized tuberculosis patients in our department. The mean age of our patients was 62.5 ± 5.8 years. Clinical findings were heterogeneous; 1 case was multifocal tuberculosis, and another case was coexistent tuberculosis and malignancy of the breast. Mammography and ultrasonography findings were suspicious for malignancy in all 4 cases. Fine needle aspiration was negative in 3 cases. The diagnosis was made in all patients by histological examination of biopsy specimens, which revealed typical tuberculous lesions. Anti-tuberculosis therapy formed the mainstay of treatment. CONCLUSION: The clinical and radiological features of mammary tuberculosis can be very confusing and easily mistaken for breast cancer. Symptoms suggestive of tuberculosis warrant a biopsy to exclude possible cancer.
