SILVA, Paulo Alexandre; FERNANDES, Maria Teresa de Fátima  e  FREIRE, Fernando Silva. Rare case of osteolipoma in the oral cavity. Rev. Assoc. Paul. Cir. Dent. [online]. 2013, vol.67, n.3, pp. 198-201. ISSN 0004-5276.

Osteolipomas are subtypes of lipoma with osseous metaplasia, mostly with bone inside and extremely rare occurrence in the oral cavity, so that in the literature, at time, there are only 12 papers. Its etiology is not well understood, several theories being described. Histologically feature mature adipose tissue surrounded by bone tissue or bone tissue inside. We present a rare case of osteolipoma oral cavity located in the mandibular fornix of a female patient, totally surrounded by mature bone tissue and completely independent of the adjacent bone tissue. After surgical removal, during six years of follow-up, there were no clinical signs of recurrence.
