Transmigrant impacted mandibular canines: a retrospective study of 15 cases.

BACKGROUND: Transmigration of mandibular canines across the midline is rare. The authors describe the clinical and radiologic characteristics of patients with transmigrant impacted mandibular canines. METHODS: The authors conducted a retrospective observational study of 14 patients with transmigrant canines. They diagnosed transmigrant canines in all of the patients on the basis of the clinical and radiological findings, and they obtained the data from the patients' case histories and panoramic radiographs. They considered a canine to be transmigrant when one-half or more of its length crossed the mandibular midline. RESULTS: There were 15 transmigrated canines in 14 patients aged 16 to 60 years. Primary canines were present in 10 cases. One case involved a pericoronal infection, two involved supernumerary teeth, one was associated with an odontoma, and in two a pericoronal radiolucency was seen that was compatible with a follicular cyst. Treatment consisted of surgical extraction for eight patients, and periodic clinical and radiologic follow-up visits for six patients. CONCLUSIONS: Radiographic examination is necessary to diagnose impacted transmigrant canines, among other anomalies. Surgical extraction is the treatment of choice for patients with transmigrant canines involving associated pathology. In some cases, the management of asymptomatic impaction can be limited to periodic clinical and follow-up visits. CLINICAL IMPLICATIONS: The absence of the permanent canine within the arch beyond the normal time of eruption suggests the presence of an impacted canine. A transmigrant canine may develop an associated pathology.

Leiomyoma of the hard palate: a case report.

Leiomyoma is a benign smooth muscle tumor that is very rarely located in the oral cavity. It is accepted that the smooth muscle giving rise to this tumor corresponds to the tunica media of the arteries. The tumor can develop at any age, with no clear gender predilection, and typically manifests as a slow-growing, asymptomatic lesion. The diagnosis is based on the histopathological study, with the use of specific staining techniques, including immunohistochemical markers. Treatment consists of complete resection of the lesion, with due safety margins. We present the case of a 57-year-old male with a tumor located for the previous four months in the region of the hard palate, adjacent to the left upper premolars. After surgical resection with safety margins, hematoxylin-eosin staining and immunohistochemical study confirmed the diagnosis of leiomyoma.

Leiomioma del paladar duro: informe de caso / Leiomyoma of the hard palate: a case report

El leiomioma es un tumor benigno del músculo liso muy poco frecuente a nivel de la cavidad bucal. Se acepta que la fuente de músculo liso originaria de este tumor es la túnica media de los vasos arteriales. Se trata de un tumor que puedeaparecer a cualquier edad, sin presentar una clara predilección por el sexo y normalmente lo hace en forma de tumoración asintomática de crecimiento lento. Su diagnóstico está basado en el estudio anatomopatológico, utilizándose tinciones específicas como podrían ser las técnicas de inmunohistoquímica. Su tratamiento consiste en la extirpación completa de la lesión con márgenes de seguridad. En este artículo se expone el caso de un paciente hombre de 57 años que presentaba una lesión en el paladar duro, adyacente a los premolares superiores del lado izquierdo, de 4 meses de evolución. Tras la exéresis quirúrgica con márgenesde seguridad de dicha lesión, se realizó su estudio anatomopatológico. La tinción con hematoxilina y eosina junto conel estudio inmunohistoquímico de la muestra confirmaron el diagnóstico de leiomioma
