Primary mature teratoma presenting as an adrenal tumor in a child.

Teratomas, rare germ tumors usually found in the ovaries and testes, are potentially malignant. Adrenal teratomas are extremely rare, and their diagnosis relies on the findings from radiologic examinations. Early diagnosis and surgical resection are important for effective treatment. The success of the treatment determines the need for postoperative chemotherapy. Because the prognosis is currently difficult to predict, close, lifelong follow-up is recommended. The present review discusses the character of mature teratomas of the adrenal gland. We report 1 case of a primary mature teratoma presenting as an adrenal tumor in a child and review the published data.
