History: A 20-year-old woman presented with chronic jaw pain and swelling in the left cheek. Computerized tomography (CT) scan identified an expansile, multilocular, osteolytic mass in the left lower maxillary sinus (Fig. 1). The mass had lobulated margins and contained microcystic elements with a large cyst measuring 24 mm. The mass was completely excised which showed dark red fluid inside the cysts. Grossly, the lesion contained heterogeneous, reddish-brown friable soft tissue fragments intermixed with hard components.
