Overview

It is thought that Struma ovarii is mediated by activation of the mitogen activated protein kinase signaling pathway as a critical step in tumorigenesis. Malignant struma ovarii (MSO) are rare tumors which arise from ectopic thyroid tissue in the ovary which is benign.

Pathophysiology

Pathogenesis

Genetics

  • Malignant struma ovarii (MSO) are rare tumors which arise from ectopic thyroid tissue in the ovary which is benign.
  • Malignant struma ovarii (MSO) are classified histologically as papillary thyroid carcinomas (PTC). The genes involved in the pathogenesis of Malignant struma ovarii (MSO) include BRAF (35% to 69%), RAS (10%), and RET (5% to 30%). [1]
  • The development of Malignant struma ovarii (MSO) along with papillary thyroid carcinomas (PTC) features is associated with mutations in the BRAF of the type which is commonly observed in PTC, therefore it suggests a common pathogenesis for all PTCs regardless of their location. On the contrary, mutations in the RET/RAS/RAF pathway are not observed in BSO (Benign Struma ovarii). [1]

Associated Conditions

Gross Pathology

  • On gross pathological examination, Struma ovarii characteristically presents as a: [16] [17]
  • Solid and cystic tumor.
  • Tumor with several nodules partially separated by gray whitish fibrous tissue.
  • Nodules appear tan-brown in color with small dark red areas.
  • Cystic spaces filled with yellow-brown or straw-colored fluid.
  • Focal areas of calcification are observed.

Microscopic Pathology

  • On microscopic histopathological analysis the tumor was initially diagnosed as granulosa cell tumor in frozen study but finally turned out to be Struma Ovarii which is the characteristic finding of Struma ovarii. [12]
  • Hematoxylin and eosin-stained tissue helps analyze branching papillae with atypical cytologic features including nuclear groves, clearing, overlapping, and enlargement, consistent with papillary thyroid carcinoma arising in a struma ovarii. [18]
