A Rare Case of Synchronous Lobular Capillary Hemangioma and Non-Lobular Capillary Hemangioma Arising From the Both Arytenoid Mimicking Laryngeal Granuloma

Laryngeal granuloma (LG) is a non-neoplastic lesion that mainly develops in the posterior vocal folds. It arises response to inappropriate use, and endotracheal intubation. Recently, it has been found coronavirus disease 2019 (COVID-19) also causes it.

The LCH usually caused by stimuli such as low-grade local irritation, traumatic injury. Despite differences, difficult differentiate them from each other, surgical biopsy necessary. rare find either or larynx, our knowledge, bilateral without intubation history smoking have never reported worldwide. Here, with review literature, we report case arytenoid mimicking LG.
