case_images: On clinical examination, there was a diffuse, proliferative soft tissue growth of the maxilla extending from the marginal gingiva in the palatal aspect of the anterior tooth and involving the entire surface of the hard palate up to the level of the hard and soft palate junction along with erythema of attached gingiva in relation to posterior teeth palatally and buccally as well as Grade III mobility of all the anterior and posterior maxillary teeth (Figures 1 and 2).
