Clinical and Radiographic Findings

The patient reported a slowly enlarging red-purple swelling lingual of the posterior mandible of one and a half years’ duration (Figure 1).  A similar, smaller swelling was removed six years ago from the same location.  The swelling was described as ulcerated and fungating but was not painful.  The swelling had displaced tooth #30 almost completely outside the dentoalveolar housing.  The first biopsy was performed in February and the lesion was completely removed in March.  The incisional biopsy taken in February measured 1.2 x 1.0 x 0.4 cm while the complete surgical specimen arrived in two sections measuring 3.5 x 3.6 x 2.0 and 2.1 x 0.7 and 0.3 cm at its greatest dimensions.  A panoramic radiograph shows that the alveolar ridge is superficially resorbed, leading to the so called “saucerization” of the alveolar bone (Figure 2).
