Objective:
To report two cases of laryngeal plasmablastic lymphoma, a rare and relatively recently described form of non-Hodgkin's lymphoma. It has not previously been described in the larynx, nor associated with upper airway obstruction.
Case Reports:
We describe the clinicopathological features of two such cases in human immunodeficiency virus positive patients, and we discuss their unusual presentations and diagnostic features.
Conclusion:
When evaluating a laryngeal tumour, plasmablastic lymphoma and other non-Hodgkin's lymphomata should be considered as differential diagnoses, particularly in the setting of a high prevalence of human immunodeficiency virus infection. Biopsy with detailed histopathological and immunohistochemical evaluation is recommended to ensure correct diagnosis and optimal management.
