benign teratoma

These structures are distinctly different from squamous papilloma and benign teratoma.

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with benign teratoma.

It could be a dermoid cyst, a benign teratoma, which was a semi-solid mass of skin, hair, teeth, lungs, or it could be a compound malignant ovarian cancer.
