Background: Mesenteric teratomas are considered rare intra-abdominal tumours with minimum clinical symptoms, which turn di cult their preoperative diagnosis. They represent a poorly studied pathology that has been established with 1 in 26,794 to 250,000 frequency of hospital admissions. It is not frequent to think about this kind of lesion in a preoperative period, and the symptoms it presents can be very ambiguous. Therefore, in this study we present a case of acute abdomen, in a 65-year-old Mexican woman, in which a mesenteric teratoma was obtained as a surgical nding.Case presentation: 65-year-old woman who presented a clinical picture of abdominal pain and distention, nausea and constipation, as well as absence of gas channeling in the last 24 hours. After 48 hours of conservative management, without favorable results and with a diagnosis of acute abdomen, surgery was entered to perform exploratory laparotomy and an intraoperative nding of mesenteric teratoma was made. Two ovoid specimens were extracted and sent to the pathology area, who con rms the diagnosis of mature cystic teratoma.Conclusions: Teratoma is commonly a germ cell tumour that originates in the gonads and is detected in women of reproductive age. This is extremely rare, with an estimated 21 cases reported to date. Despite the low frequency, it is suggested to it considered these teratomas in the differential diagnosis against other pathologies, especially if they do not show a very clear data.

Introducción. Los teratomas son neoplasias que surgen a partir de células germinales pluripotenciales y derivan de dos o más capas de células. Se clasifican en tumores maduros, que contienen tejidos bien diferenciados, o inmaduros, que contienen estructuras inmaduras y embrionarias. Su localización más frecuente son las gónadas; la ubicación mesentérica es infrecuente y se han descrito aproximadamente 40 casos en la literatura mundial. Dentro del abordaje diagnóstico y terapéutico, se emplea la tomografía computarizada y la resonancia magnética nuclear para caracterizar la lesión, evaluar la extensión intraabdominal y la relación con otras estructuras. El diagnóstico debe confirmarse mediante el examen histopatológico. Caso clínico. Paciente femenina de 56 años, con antecedente de carcinoma ductal infiltrante de mama izquierda en remisión, en estudios de seguimiento con hallazgo incidental en tomografía de abdomen de lesión abdominopélvica dependiente del mesenterio, contornos lisos y nivel grasa-líquido. Estudios de extensión con marcadores tumorales negativos. Resultados. Por la alta sospecha clínica e imagenológica de teratoma, fue llevada a resección quirúrgica de la lesión. El examen histopatológico confirmó el diagnóstico de teratoma quístico maduro del mesenterio. Conclusión. El teratoma mesentérico es una entidad clínica rara, que debe ser considerado como uno de los diagnósticos diferenciales de una masa abdominal con efecto compresivo. El diagnóstico se basa principalmente en el examen clínico y los hallazgos imagenológicos. La escisión quirúrgica temprana es el pilar del tratamiento; el abordaje laparoscópico o abierto depende de las características clínicas y la experiencia del cirujano.
