Endotracheobronchial lymphoma: Two unusual case reports and review of article.

The tracheobronchial origin of non-Hodgkin's lymphoma (NHL) is a very rare presentation, and there are only a few case reports of primary tracheal or endobronchial NHL. We have two cases of primary tracheobronchial NHL; one case was incidentally diagnosed as anaplastic large cell lymphoma of endobronchial origin when a comprehensive workup and surgery were carried out for an endobronchial aspergilloma which was actually sitting on top of lymphoma. The second patient was a case of myelodysplastic syndrome who presented with acute respiratory distress; on thorough workup, he was found to have endotracheal B-cell lymphoma. Both cases were responding well with standard chemotherapy. The mortality in these kinds of patients is due to disease progression or airway compromise and treatment complications.
