OBJECTIVE To evaluate the yield of polymerase chain reaction (PCR) for detection of Mycobacterium tuberculosis from different clinical specimens. STUDY DESIGN Observational study. PLACE AND DURATION OF STUDY Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from January 2001 to December 2010. METHODOLOGY Different clinical specimens received for Mycobacterium tu...

Hamartomas are the most common benign tumors of the lung. It is most common peripherally in the parenchyma as solitary nodule or endobronchial lesion. Endobronchial form may cause obstruction of airway, atelectasis and recurrent pneumonia. Endobronchial hamartomas may be treated by surgical intervention or bronchoscopic excision (with rigid or flexible procedures). We are presenting a case of e...

We present two patients with benign endobronchial tumours: polypi and a chondroma. Both were treated by Neodymium-YAG laser photoresection. There have been no signs of recurrence in the four years since treatment. Endobronchial resection by Neodymium-YAG laser is an effective treatment for benign endobronchial tumours.

We report a man presenting with dyspnea, cough, and hemoptysis due to left lung collapse from an endobronchial tumor obstructing the left main bronchus. Endobronchial biopsy of the tumor showed renal cell carcinoma, identical to a previous specimen of renal cell carcinoma removed by a radical left nephrectomy five years ago. The endobronchial tumor was removed by snare diathermy through a flexi...

Pulmonary mucormycosis is an uncommon infection and its endobronchial form is rare. Fever, cough, dyspnoea and hemoptysis are the usual presenting symptoms. Hoarseness of voice, a rare manifestation of endobronchial mucormycosis, has been reported earlier but its exact anatomical basis was unclear. We report an instance of polypoid endobronchial mucormycosis and vocal cord paralysis in a patien...

A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. Diagnosis of schwannoma was confirmed from the specimen obtained by ...
