An endotracheal plasmablastic lymphoma
(S. Karger AG, Basel, 2019) Bots, Eva M. T.; Opperman, Johan; Bassa, Fatima; Koegelenberg, Coenraad F. N.
ENGLISH ABSTRACT: 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. Plasmablastic lymphoma is a rare form of non-Hodgkin lymphoma and is associated with HIV. Tracheal involvement to the extent seen in our patient is exceptionally rare, and, to the best of our knowledge, has never been described.
