Abstract

Epstein-Barr virus-positive Inflammatory follicular dendritic cell/fibroblastic reticular cell tumour (EBV-IFDC/FRCT) is a rare neoplasm that occurs almost exclusively in the liver or spleen. Extra-hepatosplenic presentation is infrequent and exceptional cases have been described arising in the gastrointestinal tract or in the pharynx. However, EBV-IFDC/FRCT cases have not been previously reported in the larynx.

This report describes a case of a 32-year-old woman who arrived to the emergency department due to progressive dyspnea with associated inspiratory stridor and non-productive cough. Direct laryngoscopy showed a nodular tumour arising on the left posterior subglottic mucosa obstructing 90% of the airway. A preoperative dual energy contrast enhanced computed tomography (CECT) was performed demonstrating a low attenuation lesion on virtual non-contrast (VNC) images and vivid iodine uptake on the iodine map. The tumour was excised and the histopathological analysis led to the diagnosis of an EBV-IFDC/FRCT. A fibre-optic laryngoscopy six months after the surgery did not show any abnormalities.

Although the vast majority of EBV-IFDC/FRCT occur in the liver or spleen, some extra hepatosplenic tumours have been reported affecting the head and neck region. We describe here the first case arising in the larynx, as well as the usefulness of preoperative dual energy imaging techniques to assess these lesions, thus providing information that could have management implications.
