Mesenteric Teratoma in Adult Female: a Rare Case

Abstract

Mesenteric teratomas are considered rare intra-abdominal tumors with minimum clinical symptoms, which turn difficult 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 finding. Sixty-five-year-old woman who presented a clinical picture of abdominal pain and distention, nausea and constipation, and absence of gas channelling in the last 24 h. After 48 h of conservative management, without favorable results and with a diagnosis of acute abdomen, surgery was entered to perform exploratory laparotomy and an intraoperative finding of mesenteric teratoma was made. Two ovoid specimens were extracted and sent to the pathology area, who confirms the diagnosis of mature cystic teratoma. Teratoma is commonly a germ cell tumor 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 consider these teratomas in the differential diagnosis against other pathologies, especially if they do not show a very clear data.
