Immature Teratoma of the Ovary: A Case Report and Literature Review

Immature teratomas are rare malignant tumors representing less than one percent of ovarian teratomas, occurring in young women and adolescents. Their development arises from cells derived from the three embryonic germ layers (endoderm, mesoderm, and ectoderm). They are classified into three grades of increasing severity based on the proportion of immature neural cells. The prognosis is directly correlated with the histological grade. The therapeutic management is primarily surgical, possibly combined with adjuvant chemotherapy, while maximizing the preservation of fertility potential.
