An Endotracheal Plasmablastic Lymphoma.

We describe an exceptionally rare case of a male patient with newly diagnosed advanced human immunodeficiency virus (HIV) infection, who presented with a plasmablastic lymphoma involving the right maxillary alveolar ridge with associated cervical lymphadenopathy. On a staging positron emission tomography computed tomography (PET-CT) scan, he was incidentally found to have an endotracheal tumour involving the anterolateral aspect of the mid-trachea. The tumour appeared to be well-vascularised at bronchoscopy and was confirmed as well-differentiated plasmablastic lymphoma.

Syncope due to tracheal adenoid cystic carcinoma.

We present a case of a 34-year-old male who presented with syncope secondary to a large adenoid cystic carcinoma (ACC) of the distal trachea. A computed tomography and flexible bronchoscopy showed almost complete occlusion of the distal trachea. Resection with curative intent was performed, but resection margins were unfortunately not clear.
