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.
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.
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.
性腺外腹膜内畸胎瘤非常罕见，尤其是那些起源于肠系膜和结肠系膜的畸胎瘤。在当代文献中，仅报道并描述了22例此类肿瘤。
我们报告一例52岁女性患有乙状结肠系膜良性囊性畸胎瘤。患者表现出轻度肠梗阻的临床症状。骨盆和腹部计算机断层扫描显示左半腹下部有一个9.7×8.9×9.4 cm的巨大钙化肿瘤。结肠镜检查在距肛缘35 cm处证实存在管腔外梗阻。术中发现乙状结肠系膜的囊性钙化肿瘤导致左半结肠管腔外梗阻。切除肿瘤并对粘连的大网膜进行了部分切除。组织病理学检查显示为良性囊性畸胎瘤。
鉴于肠系膜畸胎瘤是极其罕见的肿瘤，很难为患有此类肿瘤的患者指定一个通用的充分治疗结论。为了建立正确的组织病理学诊断并缓解患者症状，建议进行完整的手术切除。
