Spontaneous pneumothorax in lymphomatoid granulomatosis.

Lymphomatoid granulomatosis is a unique form of pulmonary angiitis and granulomatosis characterized histologically by a necrotizing angiocentric and angiodestructive lymphoid infiltrate, which in most cases represents a proliferation of Epstein-Barr virus infected B-cells, with a prominent T-cell reaction. The most common radiographic findings in lymphoma-toid granulomatosis are multiple rounded mass densities, often suggestive of metastatic tumour. We report a case of spontaneous pneumothorax with bronchopleural fistula in a patient suffering from lymphomatoid granulomatosis.
