  • This paper reports the clinical case of a 26-year-old adult female diagnosed with a mature ovarian teratoma. Ovarian teratomas are germ cell tumors composed of tissues derived from all three embryonic layers, more frequently seen in young women but rare in adults. The patient presented with severe lower abdominal pain; imaging revealed a 20 cm heterogeneous mass in the right ovary with hyperechoic areas suggestive of fat and calcifications. Emergency laparotomy with cystectomy and ovarian tissue preservation was performed due to suspected torsion. Histopathological examination confirmed a mature teratoma without malignancy. The postoperative course was favorable, with preserved ovarian function and no tumor recurrence during follow-up. This case highlights the relevance of early diagnosis and timely surgical management to prevent complications and preserve fertility in young women.
