case_images: On examination, there was a smooth mucosa covered dumbbell-shaped swelling occupying the oral cavity, eroding the posterior part of the upper alveolus and the adjacent hard palate on the right side extending in to the maxillary sinus [Figure 1].
case_images: Magnetic resonance imaging of the paranasal sinuses: Laterally, the mass was extending in to the buccal space and medially in to the oral cavity. Superiorly, the mass was eroding the floor of the maxillary sinus, completely occupying the antral cavity, occluding the osteomeatal complex. Anteriorly, the mass was eroding the maxilla up to the first molar tooth
