There is an ambiguous and controversial line between fetiform teratoma and fetus in fetu (FIF) as differential diagnoses of a fetiform mass. Classically, the presence of vertebral column often with a relatively proper arrangement of other organs around the central axis favor the diagnosis of FIF over teratoma.
Based on previously proposed criteria and the presence of vertebral organization in the radiological and histopathological assessment of the fetiform mass, we present an extremely rare case of adnexal FIF in a 10-year-old girl presenting with acute abdominal pain.
Whether FIF and fetiform teratoma are one entity or two, clinical discrimination for the choice of treatment seems to be unnecessary and the patient should be clinically followed for the probable malignant potential.
在鉴别诊断胎形畸胎瘤和胎儿内胎（FIF）时，两者之间的界限存在模糊和争议。经典地，存在脊柱，通常伴随着中央轴周围其他器官的相对适当排列，这有利于 FIF 而非畸胎瘤的诊断。
基于先前提出的标准和对胎形肿块的影像学和组织病理学评估中存在的脊柱组织，我们提出了一个极其罕见的 10 岁女孩附件 FIF 的病例，该女孩表现为急性腹痛。
无论 FIF 和胎形畸胎瘤是否为同一实体，为选择治疗方法进行临床鉴别似乎是不必要的，患者应进行临床随访以评估可能的恶性潜能。
