The teratoma is a dysgenetic tumor consisting of tridermal differentiation products. The most common classification is made according to maturity - benign adult teratoma and malign nonmature embryonal teratoma. In the case demonstrated, a 15-year-old male suffers from tiredness, paleness and pains in the epigastrium. The radiological examination showed a tumor in the size of a fist with a number of teeth located partly within the stomach. The histological findings after operation confirmed the diagnosis of a coetaneous (= adult) gastric teratoma. The discussion shows that all cases of gastric teratoma published until 1972 are male, in 77% under the age of 1 year, in 13% under the age of 10, and only in 10% over the age of 10 years.
畸胎瘤是一种由三胚层分化产物构成的发育异常肿瘤。最常见的分类是根据成熟度——良性成人畸胎瘤和恶性未成熟胚胎性畸胎瘤。在所示病例中，一名15岁男性出现疲倦、面色苍白和上腹部疼痛。放射学检查显示一个拳头大小的肿瘤，有一些牙齿部分位于胃内。手术后的组织学检查结果证实为实性（即成人型）胃畸胎瘤。讨论表明，截至1972年发表的所有胃畸胎瘤病例均为男性，77%在1岁以下，13%在10岁以下，仅10%在10岁以上。
