Clinical pathology conference case 5: bilateral maxillary sinus resorptive disease with palatal ulceration in a 42-year-old patient

Abstract

A 42-year-old female presented with bilateral periodontal swellings of 6 months’ duration in the maxillary area palatal to the maxillary molar and premolar teeth. The lesions had been treated by a general dentist as localized periodontal disease, and because of local pain, root canal treatment of tooth #2 was administered. As a result of medial expansion of the lesions toward the hard palate (Figure 1) over the next few months and the occurrence of pus-like discharge, orthopantomography (Figure 2) and computed tomography (CT) (Figure 3) were performed, and the examinations showed bilateral lytic lesions of the hard palate involving the roots of teeth # 4 to #14, respectively.
