Le rhabdomyosarcome est la tumeur mésenchymateuse la plus fréquente chez l'enfant et l'adolescent. Il représente 60 à 70% des tumeurs mésenchymateuses et environ 5% de l'ensemble des tumeurs solides à ces âges. Près de la moitié des rhabdomyosarcomes surviennent au niveau de la tête et du cou. Nous rapportons le cas d'un rhabdomyosarcome agressif à localisation temporo-pariétale. Chez un jeune adolescent de 20 ans avec une forme histologique nouvelle.

Idiopathic gingival fibromatosis is a rare benign oral disorder characterized by non-hemorrhagic, gradually progressive fibrous gingival enlargement. This overgrowth can be so severe that it can impact both maxillaries, on lingual and buccal sides, sometimes completely covering the crowns. This condition can begin during primary dentition and continue throughout adulthood, setting up a cascade of stomatognathic and psychological negative effects. Herewith, we report a case of a non-syndromic 14 year old female who presented with generalized severe gingival enlargement involving both arches and subsequently diagnosed as idiopathic gingival fibromatosis. The chief complaints were unaesthetic appearance and lack of eruption. The excess tissue was surgically removed under general anesthesia, using electrosugery. The patient was issued regular follow-ups to ensure proper oral hygiene and periodontal controls. Awareness of this condition is of utmost importance for early diagnosis and to prevent further complications spilling into adult age.

After the first report of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in 2003, it has increased significantly since then. We report a very rare extensive case never seen before in our experience of bone exposure with necrosis reaching the mandibular inferior border. Although the treatment modalities are not yet established, most researchers have recommended conservative approaches. The surgery was to be as conservative as possible, with a resection of the mandibular range followed by reconstruction using titanium plate with space maintainer. The authors would like to share their approach, management, and awareness.
