Ovarian yolk sac tumors (OYSTs), also known as endodermal sinus tumors, are rare and highly malignant germ cell tumors, accounting for approximately 1% of all ovarian cancers. They predominantly affect children and young adults, with a rapid growth rate and early metastasis, making early diagnosis and treatment crucial. This report presents the case of a 6-year-old female from a low-resource setting who initially presented with symptoms suggestive of acute appendicitis, including abdominal pain, fever, and vomiting.

Article Synopsis
- - Mediastinal yolk sac tumors (YST) are aggressive tumors that are often advanced and difficult to remove at the time of diagnosis, lacking a standardized treatment protocol due to their rarity.
- - The common treatment involves a combination of chemotherapy with cisplatin followed by extensive surgery, as tumors often invade nearby structures like the lungs and heart.
- - This review analyzes existing literature on surgical methods for treating YST, noting the limited information available and aiming to provide clinicians with a better understanding of the complex surgical approaches involved.
