Introduction. Extragonadal intraperitoneal teratomas are very rare,
especially those arising from mesentery and mesocolon. In the contemporary
literature only 22 cases of such tumors have been published and described.
Case Outline. We report a case of a 52-year-old woman with a benign cystic
teratoma of the mesosigmoid. The patient presented with mild clinical signs
of intestinal obstruction. Computerized tomography of the pelvis and abdomen
showed a large 9.7 × 8.9 × 9.4 cm calcified tumor in the lower part of the
left hemiabdomen. Extraluminal obstruction was verified by colonoscopy at 35
cm from the anal verge. Intraoperatively, a cystic calcified tumor of the
mesosigmoid was found causing extraluminal obstruction of the left colon. The
tumor was extirpated and a partial resection of the adherent great omentum
was performed. The histopathological examination revealed a benign cystic
teratoma. Conclusion. Considering the fact that mesenteric teratomas are
extremely rare tumors, it is difficult to designate a general conclusion for
an adequate treatment of patients suffering from them. Complete surgical
excision is indicated in order to establish a correct histopathological
diagnosis and to relieve the patients of symptoms.
