Oral leiomyoma in retromolar trigone. A case report.

Leiomyomas are bening tumours originated on smooth muscle. The most frequent site of appearance are uterine myometrium, gastrointestinal tract and skin. The highest incidence occurs between 40 and 49 years of age. Its presentation is unusual in children or in older patients. Leiomyomas are unfrequent in the oral cavity, but in this location are usually localized on tongue, lips and palate. Leiomyomas use to appear as well-defined masses, with slow growth and totally asymptomatic. Pain is present just in rare cases. The treatment is surgical escision. Recurrences are extremely unfrequent. The diagnosis is mainly determined by histological studies due to its unspecific clinical appearance. Histopathologically proliferation of smooth muscle cells is observad without necrotic areas. A low number of mitotic figures can be seen. We present the case report of a 25-year old male patient, with a leiomioma on his right retromolar trigone. The low incidence of this pathology, the age of the patient and the unusual location, make the report of the case worthy.

Oral leiomyoma in retromolar trigone. A case report

Los leiomiomas son tumores benignos originados en el músculo liso. Su localización más frecuente es el útero, el tracto gastro-intestinal y la piel. Se presenta habitualmente entre los 40 y 49 años de edad, siendo muy rara su aparición en la infancia y en la senectud. Son muy infrecuentes a nivel de la cavidad oral, pero cuando se dan en esa localización, asientan principalmente en la lengua, los labios o el paladar. Inicialmente suelen presentarse como una masa muy bien definida, de lento crecimiento y totalmente asintomática. En raras ocasiones producen dolor. Su tratamiento es casi siempre quirúrgico, siendo las recurrencias excepcionales. Dada su clínica inespecífica, su diagnóstico es principalmente histológico, observándose en las muestras una proliferación de células musculares lisas, sin focos de necrosis y con escasas mitosis. Presentamos el caso clínico de un paciente de 25 años de edad con un leiomioma en trígono retromolar derecho. Dada la escasa incidencia de este tipo de patología, la edad del paciente y su inusual ubicación, se justifica la presentación de este caso
