Bronchocentric granulomatosis with extensive cystic lung disease in tuberculosis: An unusual presentation.

Tuberculosis is known to cause both cystic lung disease and bronchocentric granulomatosis (BCG). However, both are rare manifestations of this common disease. We report a case of BCG with extensive cystic lung disease in a young female who presented with fever, weight loss, and recurrent pneumothoraces with respiratory failure. Early diagnosis and treatment are imperative, as appropriate therapy may be life-saving in such cases.

Phenytoin-induced acute hypersensitivity pneumonitis.

Lungs are target organs for toxic effects of various drugs due to many reasons. Diphenylhydantoin (DPH) is reported to have many extrapulmonary side effects. We are presenting a case of acute hypersensitivity pneumonitis (HP) secondary to DPH, presenting with respiratory failure. Acute HP with respiratory failure is an uncommon drug side effect of the DPH therapy and is a diagnosis of exclusion. It requires detailed workup and exclusion of other causes along with evidence of improvement in the patient's condition after withholding DPH.

Sarcoidosis as unusual cause of massive pleural effusion.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Pleural involvement is relatively rare. Development of pleural effusion in sarcoidosis needs to be evaluated for other causes, especially tuberculosis in endemic countries. Sarcoid pleural effusion responds to systemic corticosteroids. We are presenting case of 42 year old male patient of sarcoidosis who developed massive pleural effusion while on treatment with steroids, which was attributed to disease per se. Sarcoidosis as a cause of massive pleural effusion has not been mentioned before in published literature.
