Fertility preservation for a patient with advanced immature teratoma of the ovary is reported. The patient, a 29-year-old woman, delivered a healthy baby after having had ovarian immature teratoma, grade 3, uncertain stage, at 13 years of age. She was initially treated with unilateral salpingo-oophorectomy and a contralateral wedge resection for tumor invasion, followed by a 6-course cisplatin+...

The pancreatic teratoma is a congenital tumor which results from abnormal embryonic development of totipotent cells. The preoperative diagnosis is challenging. We report, to our knowledge, the 26th case in a 64-year-old man in whom the diagnosis was made preoperatively on imaging.

A 21 year old female presented with incidental findings of complex anterior mediastinal mass. This patient was otherwise healthy, without contributory medical, surgical, family or social history. CT imaging identified a right paracardiac mediastinal mass with components of variable attenuation, including fluid, soft tissue and fat components. Mediastinal mature teratoma was suspected. Cystic or...

Germ cell tumors are derived from the primordial germ cells of the ovary and immature teratoma is the second most common germ cell malignancy. About 50% of pure immature teratomas of the ovary occur in women between the ages of 10 and 20 years, and they rarely occur in pregnancy. A 21-year-old woman, gravid 1, para 0, at 18 weeks of gestation, was incidentally diagnosed with a right ovarian mas...

Immature mediastinal teratoma is very rare, found in only 1% of all mediastinal teratomas. Raised serum alpha feto-protein acts as important surrogate marker for both diagnosis and follow up in such cases. Surgery and adjuvant chemotherapy are keys in the management, especially in patients older than 15 years of age. We present a 14-year-boy presenting clinico-radiologically as left sided massi...

This study aimed to investigate an unusual case of immature ovarian teratoma with onset of mature glial cells implanted on the contralateral ovary, a challenge in the diagnosis of the second ovarian tumor. We report the case of a 31- yr-old woman, who developed at the age of 16 an immature teratoma in the right ovary that was surgically removed. Six years later mature glial implants were presen...

Background. Although some mature cases of teratomas have recently been described in the cervix, they are not commonly found in the uterus, especially in immature forms. An immature uterine teratoma relapsing after surgery as malignant neuroepithelioma has never been reported in the literature. Case Presentation. We describe a case of immature teratoma which occurred primarily in the uterus in a...

Sacrococcygeal teratoma (SCT) is the most common congenital tumor in neonates. SCT may be benign (mature and immature) or malignant. Malignancy is rare in SCT diagnosed before 2 months of age. Here, we describe a neonate having a mature teratoma with a focus of malignant yolk sac tumor within and the difficulties faced in its management.
