Incidence, clinical characteristics, and survival outcomes of ovarian strumal diseases: a retrospective cohort study.

ABSTRACT:

Background

Struma ovarii (SO) is a rare tumor and may transform into ovarian strumal carcinoid (OSC) and/or malignant struma ovarii (MSO), but the incidence, clinical characteristics, and survival outcomes have not been well defined.
