Findings

No curated finding names struma ovarii yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

An ovarian mature teratoma characterized by the presence of aberrant thyroid tissue. The aberrant thyroid tissue shows morphologic changes identical to thyroid adenoma or carcinoma. Patients may present with abdominal mass and unusual symptoms due to thyrotoxicosis, or Meigs syndrome (ascites and pleural effusion).
