case_images: The CT showed a focal area of bone thinning and focal dehiscence at the floor of the right maxillary sinus without evidence for frank tumor extension into the sinus (Figures 2(a) and 2(b)).

case_images: The secretory material from the glandular spaces was noted to be periodic acid Schiff- (PAS-) positive and diastase-resistant (Figure 3).
case_images: MASC tumor comprised of cells forming microcystic and glandular spaces containing eosinophilic homogenous material (H&E, magnification x200).

case_images: The surgical site was allowed to heal by secondary intention with granulation tissue (Figure 8).
