Which type of ovarian tumor typically presents as unilateral, solid, and yellowish to gray-pink in appearance?

The type of ovarian tumor that typically presents as unilateral, solid, and yellowish to gray-pink in appearance is a dysgerminoma. Dysgerminomas are a type of germ cell tumor and are considered analogous to seminomas in men. They are known for their solid texture and often have a yellowish to gray-pink coloration due to their cellular composition and the presence of lipids.

Dysgerminomas usually originate from the germinal epithelium of the ovary and are characterized by their well-defined borders and soft consistency. These tumors frequently occur in young women and can produce elevated levels of specific tumor markers, such as lactate dehydrogenase (LDH).

Other ovarian tumors, such as endometrioid and clear cell tumors, typically display different histological features, growth patterns, and colors, making them distinct from dysgerminomas. Granulosa cell tumors, being sex-cord stromal tumors, would present differently, often having a more cystic nature and associated hormonal activity.
