Mature teratoma of the uterine corpus with thyroid differentiation

A case of a clinically silent mature teratoma of the uterine corpus is reported. A 55‐year‐old woman presented with multiple uterine leiomyomas. The discovery was incidental, because the patient was asymptomatic. Macroscopically, a colloid–hemorrhagic‐looking nodule was present. Histologic and immunohistochemical studies showed that this tumor was a small thyroid mass. Key words: , ,
