[Diagnosis and treatment of mature adrenal teratoma].

To discuss the pathology, clinical manifestation, diagnosis, therapy and prognosis of mature teratoma in adrenal gland. We reported 2 cases of mature adrenal teratoma and summarized their characters. No local recurrence or metastasis was found in the close follow-up of the 2 patients after the radical resection. Teratomas are rare germ tumors with potential malignant character which usually occur in the testes and ovaries. Adrenal teratomas are extremely rare and the diagnosis relies on radiological examinations. Early diagnosis and early surgical resection are the key in the treatment. Whether the postoperative chemotherapy is needed depends on the pathological result. Close lifelong follow-up is recommended and the prognosis is unclear at present.
