Ovarian embryonal carcinomas are rare and malignant germ cell tumours of the ovary.
It is found predominantly in children and adolescents (average age 14 years).
Pure embryonal carcinoma is rare and embryonal carcinoma often occurs mixed with other malignant germ cell tumour types.
Predominantly solid, but nonspecific imaging features on ultrasound, CT, and MRI, that overlap with other germ cell tumours 3. Abnormal serum markers in the setting of an adolescent with a unilateral solid ovarian mass would put the tumour on a differential diagnosis.
Treatment and prognosis
For this malignant tumour, staging laparotomy and salpingo-oophorectomy is an accepted treatment, followed by chemotherapy.
