The botryoid odontogenic cyst is a rare asymptomatic lesion characterized by its typical multilocular aspect similar to a bunch of grapes commonly affecting the mandible bicuspids and canine region. The possibility of this lesion representing a clinical variation of the lateral periodontal cyst is source of discussion and doubt among many authors. Our article reports a rare case of the polemic odontogenic cyst and presents considerations related to its etiopathogenic, diagnostic and therapeutic aspects.
RESUMOPoucos relatos de lipoma intramuscular na região temporal são vistos na literature. Devido as suas características invasivas, essa neoplasia pode ser confundida com um lipossarcoma. Apesar de exames de imagem ajudarem no diagnóstico diferencial entre lesões lipomatosas benignas ou malignas, o exame histopatológico é o único capaz de diagnóstico definitivo. Remoção total da lesão é essencial pois a taxa de recidiva sem completa excisão pode ser de até 62,5%. Uma paciente com um lipoma intramuscular localizado na região temporal é apresentada com o devido tratamento da lesão. Grande importância deve ser dada a essas lesões incomuns que podem se apresentar como um desafio aos profissionais que atuam na região maxilofacial.

Neoplasms of salivary glands represent a small group among the diseases involving the head and neck complex. In this group, the pleomorphic adenoma is the most frequent neoplasm, yet involves the submandibular gland in only 12.3% of cases. A patient presenting a swelling in the region of the submandibular gland was submitted to an incisional biopsy, where a fragment of the gland and one juxtaposed node were removed. Histologically they were defined as pleomorphic adenoma. Later, the patient was submitted to submandibulectomy and two other nodes were found close to the gland and removed. All specimens were histologically defined as pleomorphic adenoma. This multicentric finding is of great interest, perhaps explaining the recurrence rate of this neoplasm. The patient is in continuous follow-up and has not presented signs of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
