Malignancy per se and cytotoxic chemotherapy given for its treatment both are recognised risk factors for the development of tuberculosis (TB). However, individual case descriptions of pleural tuberculosis (TB-PE) following chemotherapy for lung cancer (LC) have not been published previously. We herein report the first two cases of histopathologically proven TB-PE following LC chemotherapy. The first patient was a 38-year-old man with stage IV non-small cell LC (adenocarcinoma) who developed TB-PE following four cycles of chemotherapy (pemetrexed-cisplatin). The second patient was a 49-year-old man with extensive disease small cell LC who developed TB-PE after six cycles of chemotherapy (irinotecan-cisplatin). In both patients, diagnosis of TB-PE was established by demonstration of granulomatous inflammation, caseous necrosis and positive stain for acid-fast bacilli in pleural biopsy specimens. Both cases responded to standard four-drug antitubercular therapy. These cases highlight the importance of carrying out an extensive evaluation for exudative pleural effusions in LC patients receiving chemotherapy, especially in countries with high TB prevalence. Attributing such pleural effusions to disease progression, without histopathological confirmation, may be associated with disastrous consequences. [ABSTRACT FROM AUTHOR]

Pulmonary hamartomas are usually clinically silent and found incidentally on chest radiographs. They can lead to diagnostic confusion especially in patients who have been previously treated for primary cancers at other sites. This can lead to consideration of metastatic malignancy as the primary diagnostic possibility. In this case, evaluation of a solitary pulmonary nodule (SPN) in a patient with carcinoma of tongue led to the diagnosis of pulmonary chondroid hamartoma. This highlights the fact that a pulmonary nodule in a patient with progressive cancer at another site does not always indicate pulmonary metastasis. [ABSTRACT FROM AUTHOR]

Foreign body aspiration can infrequently occur following trauma. Tooth aspiration after trauma is a rare clinical scenario. Here, we report a case in which tooth aspiration after trauma led to a presentation of acute respiratory failure with clinical findings mimicking tension pneumothorax. Successful removal of the aspirated tooth was accomplished by rigid bronchoscopy. Tooth aspiration must be considered in the list of differential diagnosis for any patient having signs or symptoms of respiratory distress following trauma especially maxillofacial trauma.

The article discusses case stiudy of a 14-year-old girl with insidious onset dyspnoea. It is informed that she had taken successful antituberculous treatment for sputum smear positive pulmonary tuberculosis (TB) three years earlier. It is informed that massive hyperinflation and anterior herniation of left lung were demonstrated in the Computer Tomography (CT) scan.
