Immature teratomas of the genital tract in older women

Immature ovarian teratoma in childhood: Case report of successful management of a monster mass in a preschool girl

Introduction

Ovarian teratomas are most common germ cell neoplasms. Immature ovarian teratoma comprises less than 1% of all ovarian teratomas. It usually occurs in first two decades of life.

Case presentation

We report a case of 4 years old female child presenting with pain and huge lump in lower abdomen. On abdominal ultrasonography, it revealed a solid-cystic pelvic lesion arising from left ovary. Magnetic resonance imaging (MRI) corroborated the ultrasonographic findings. She underwent laparotomy with right oophorectomy with excision of the mass. The histopathological examination of the excised mass confirmed it to be immature ovarian teratoma with yolk sac tumor. The patient had an uneventful recovery with no sign of tumor recurrence at a one and a half year follow-up.

Conclusion

In spite of immature ovarian teratomas having aggressive behaviour and lethal outcome, a high degree of suspicion and timely management can translate into a very good eventual prognosis.

•

In ovarian mass, patient usually presents with non-specific complaints but a high degree of suspicion and imaging is very important for diagnostic work up.

•

Now-a-days tumor markers have also proved to be an important tool for screening the patients of ovarian mass.

•

Early diagnosis and management do reduce the risk of complications like torsion, rupture, hydroureteronephrosis and gastrointestinal obstruction.

•

It also reduces the probability of metastasis and hence improves event-free and overall survival of the patient.

Mature solid teratoma of the fallopian tube associated with uterine leiomyomas

Benign solid teratomas within the fallopian tube are rare. The incidence of this kind of benign solid teratoma of the fallopian tube associated with intrauterine leiomyomas is extremely low and may complicate the clinical manifestations. Here, we report a 40-year-old female with periodic lower abdominal pain and hypermenorrhea who was found to have 3 nodules within the uterine myometrium and left distended fallopian tube. Final pathology revealed benign solid teratoma of the fallopian tube associated with 3 intrauterine leiomyomas. Primary teratoma of the fallopian tube is extremely uncommon. Gynecologic oncologists should be aware of the possibility of this disease entity when making differential diagnoses.

[The ovarian immature teratoma with gliomatosis peritonei]

OBJECTIVE

We return a case of ovarian immature teratoma with peritoneal gliomatose at a woman aged of 20 years.

MATERIAL AND METHODS

The diagnosis discovered following pelvic mass increasing volume and treaty by a one-sided annexectomy, with chemotherapy.

RESULTS

Eighty-seven cases have been published in the literature. Although potential for recurrence is high, the risk of malignancy is very low.

CONCLUSION

Ovarian immature teratoma is a malignant germ cell tumor and represents less than 1% of ovarian malignant tumors. Tissues are derived from the three germ layers (endo-, meso- and ectoderm). Tumor grading is based on the amount of immature neuroepithelium present. The prognosis is directly correlated to histological grade. Rapid (fast) growth leads to large tumors with an early diagnosis. Gliomatosis peritonei is a rare situation, characterized by the recurrence of peritoneal implants after the surgical treatment of ovarian teratoma. This entity does not modify the good prognosis of mature teratomas, but we recommend regular follow-up.

Immature ovarian teratoma in a young girl: very short course and lethal outcome. A case report

Immature teratomas of the ovary represent less than 1% of all ovarian teratomas. They contain several tissues that derive from the three embryologic layers: ectoderm, mesoderm, and endoderm. We report the case of a 17-year-old girl who presented with an immature teratoma of the left ovary that recurred 3 months later as an inoperable malignant neuroepithelial peritoneal tumor resembling a glioblastoma. She died 3 weeks after the second explorative operation. The very aggressive course and fast lethal outcome could be explained by the patient's refusal to receive chemotherapy after the initial operation.
