[2025-09-30T02:23:37.947338] [PI reasoning] **Analyzing ovarian mass case**

I need to tackle a multiple-choice question about an ovarian mass in an 18-year-old female with elevated LDH. Among germ cell tumors, dysgerminoma is linked to this elevation. Other tumors, like yolk sac or teratomas, have different markers, so dysgerminoma is the likely choice. I'll confirm this by finding literature that cites LDH as a tumor marker for dysgerminoma. I plan to do a straightforward search for relevant studies on this connection.
