Struma Ovarii: 3 years’ experience of a tertiary center
Abstract
Struma Ovarii: 3 years’ experience of a tertiary center
Objective: Struma ovarii accounts 0.5-1% of all ovarian tumors and
2-5% of ovarian teratomas. Struma ovarii cases are usually benign, only 5-10%
of cases are malignant and the most common type of malignancy is papillary
thyroid carcinoma(70%). The struma ovarii may be seen in all ages but it is
generally seen in 5th and 6th decade of life. Although most of the cases are
benign, clinical and radiological similarities to malignant masses leads to
treatment with laparotomy. In the present study 3 years’ experience of a
tertiary center's struma ovarii cases were studied.
Material-Methods: Patients who underwent surgery
for adnexal masses were investigated from achieves of the hospital. Among
pathology results 6 patients with struma ovarii were detected.
Results: When the ages
of the patients are evaluated, the youngest patient was 29 years old and the
oldest patient was 71 years old age. Two of the patients were in the fourth
decade and remaining two were in the fifth decade Maximum size of the adnexal
mass 18 cm and the minumum size was 6 cm in lenght.Among 6 cases of struma
ovarii 3 of them had a frozen section diagnosis of struma ovarii. In final
histopathological diagnosis 3 of the cases had accompanying malignancies. One
of the malignant case was a metastasis of breast carcinoma to struma ovarii.
Conclusion: Struma ovarii is a monodermal teratoma where there
is extensive differentiation to thyroid tissue. Among ovarian tumors, it
accounts 0.5-1%. A total number of 185 patients underwent surgery in our center
for ovarian masses in the last 3 years. Six struma ovarii cases were detected
among those cases which approximately accounts 3.2% of all ovarian mass cases.
This increased ratio may be attributable to the status of our center in which
complicated cases are referred. Struma ovarii cases are generally benign in
nature. Only 5-10 % of malignant cases are detected in struma ovaries. The
mostly seen malignancy in struma ovarii is the papillary thyroid carcinoma. Among
our 6 cases, one patient (16%) had a malignancy of papillary carcinoma.
Similarly, Wei et al. showed 10 papillary carcinomas among 96 cases of struma
ovarii. Although struma ovarii has a benign course macroscopic and microscopic
examinations are important to detect rare malignancies. In most of the cases,
the course of strumosis is uneventful. In our cases, patients are followed up
without disease. Struma ovarii may show changes similar to thyroid pathologies.
Hashimoto like thyroiditis may be seen. Patients may have simultaneous thyroid
pathology. In our series preoperative and postoperative TSH levels and thyroid
ultrasound of all patients were in normal range. As a conclusion Struma ovarii
cases are generally benign in nature but malignancy risk and accompanying
thyroid diseases should be kept in mind during follow up of struma ovarii
cases.
