Kim, Cho, Lee, Lim, Park, and Kim: A Case of Adrenal Teratoma


Teratoma is a congenital tumor containing tissues derived from all germ layers. Teratoma in the region of the adrenal gland is a very uncommon retroperitoneal tumor. Only 7 cases of adrenal teratoma have been reported worldwide, but in Korea, no similar cases have been reported until now. This case report describes an adrenal teratoma in a 38-year-old healthy woman who was incidentally diagnosed with a left adrenal mass on abdominal ultrasonography during a medical inspection. Computed tomographic scans revealed a 9-cm heterogeneous circumscribed round mass, containing primarily fat tissue, and a solid calcification component in the left adrenal gland. Adrenal hormonal assessment results and biochemical markers for gonadal neoplasia were negative. Result of serum laboratory tests were normal. The patient underwent laparoscopic adrenalectomy. Histologic analysis confirmed the diagnosis of a mature teratoma; the obtained specimen measured 5 × 7 × 7.5 cm and weighed 267 g. The surface of the mass was smooth, and sebaceous tissue and hair with hard material were observed on the incisional surface. The patient was discharged on postoperative day 4, without complications. In this case report, we describe the incidental finding of a teratoma occurring in the adrenal gland region in a healthy woman; the teratoma was laparoscopically excised.
