“…A teratoma is a tumor derived from germ cells that may contain multiple types of tissue (1)(2)(3). It may develop anywhere in the body, but is most commonly encountered as sacrococcygeal, retroperitoneal, ovarian and testicular teratoma.…”

Retroperitoneal teratoma misdiagnosed as a gastric stromal tumor: A case report

The misdiagnosis of retroperitoneal teratoma as a gastric stromal tumor is rarely reported. There are numerous abdominal organs, and retroperitoneal tumors are easily concealed by organs situated more anteriorly on the abdomen; therefore, retroperitoneal tumors are easily misdiagnosed as human digestive system tumors by abdominal surgeons. We herein present the case of a 39-year-old female patient who was diagnosed with a gastric stromal tumor (GST) on preoperative examination, whereas the postoperative diagnosis was retroperitoneal mature cystic teratoma. Such cases are clinically rare. In the present case, the tumor was located in the retroperitoneum, near the lesser gastric curvature, without an obvious gap. The anterior surface of the tumor was concealed by the lesser gastric curvature and did not move significantly with breathing and changes in posture. In such cases, a preoperative misdiagnosis is very likely. The aim of the present study was to improve our understanding of the presentation of retroperitoneal teratomas, thereby gaining more clinical experience and hopefully reducing the rate of misdiagnosis.

“…Teratomas may occur in various parts of the body. They may originate from embryonic and primordial germ cells, embryonic mesenchymal stem cells or embryonic carcinoma cells, and usually contain three embryonic components, which have evolved from the inner, middle and outer primitive embryonic layers (1)(2)(3).…”

“…Although most teratomas are mature teratomas, which are benign, they have the potential to become malignant and, as they increase in size, can compress surrounding organs and even rupture bleeding and infection. Therefore, once diagnosed, surgery should be performed as soon as possible ( 6 ). The surgeon may choose open surgery or laparoscopic surgery, based on the patient’s specific condition and the surgeon’s own experience, and the key to treatment is complete removal of the tumor ( 7 ).…”

Teratomas are very rare, originating from embryonal germ layers. The majority of them are mature, most common in the gonads, and with only 15% out of gonads. In particular, primary adrenal teratomas are extremely rare. The present study reported a case of a young female patient with right adrenal tumor who underwent intermittent pain in the right waist and abdomen and whose CT of adrenal gland showed an 88 mm × 79 mm × 69 mm mass. Besides, her adrenal gland-related hormones are not abnormal. Laparoscopic adrenal tumor resection was performed on her and the histopathological results confirmed that the mass was mature adrenal teratomas. As a newly diagnosed case, strict and regular follow-up is needed, and it is also necessary to detect her AFP and check her adrenal CT in the future. In addition, we have reviewed the literature from 1952 to the present, and a total of 49 cases of adrenal teratoma have been identified and analyzed.
