The mandible demonstrated an extensive expansile lytic lesion about 6.5 cm (antero-posterior) x2.5 cm (transverse) involving the posterior part of the body and angle on the right side (Figures 1 and 2). The lesion was seen surrounding the roots of mandibular right second premolar, permanent mandibular right first molar and permanent mandibular right second molar with multiple thin and thick septae intervening the lesion (Figure 1).

The mandible demonstrated an extensive expansile lytic lesion about 6.5 cm (antero-posterior) x2.5 cm (transverse) involving the posterior part of the body and angle on the right side (Figures 1 and 2). There was also an evidence of break in the lingual cortex along the postero-inferior border of the mandible (Figure 2).

An incisional biopsy revealed typical odontogenic epithelium in a plexiform ameloblastomatous pattern with interspersed prominent endothelial-lined blood filled spaces (Figure 3).
