Management of metastatic struma ovarii with papillary thyroid carcinoma and a neuroendocrine component: A case report

Abstract

Struma ovarii is a rare form of teratoma that is invariably benign. When neuroendocrine and thyroid tissue both coexist within the ovary, the term strumal carcinoid is often used. The incidence of malignant transformation in this lesion has been rarely described in the literature. Here, we present a case in which the thyroid component metastasized widely throughout the peritoneum.
