Struma ovarii: un tumor ovárico infrecuente

Struma Ovarii associated with Pseudo-Meigs Syndrome and elevated serum Ca 125: Case report and literature review

“…The age of presentation is similar to that of mature cystic teratomas, with the peak incidence in the fifth and sixth decades of life. 2 Although cases have been reported between the ages of 23 and 71 years, very similar to our patient, which was 72 years old. 16 In 5-10% they are usually malignant; although their behavior is predominantly benign.…”

“…17 It is usually unilateral (mainly right), although in 6-15% it is bilateral. 2,7,16 It should be noted that our report presented unilateral right, as reported in the literature. In 20-44% of cases it is asymptomatic.…”

“…The most frequent symptom is pelvic pain, followed by pelvic mass. 2,16 Ascites occurs in 10-17%, however, the association of ascites and hydrothorax with this tumor is rare, and despite its prevalence, we observed presence of recurrent and progressive ascites of unclear etiology, as well as pleural effusion predominated right hemithorax. Symptoms of hyperthyroidism occur in 8% of cases, it is noteworthy that the patient's course is asymptomatic; however, with hyperthyroidism at the time of diagnosis.…”

“…Symptoms of hyperthyroidism occur in 8% of cases, it is noteworthy that the patient's course is asymptomatic; however, with hyperthyroidism at the time of diagnosis. 2,7,16 As previously mentioned, the Pseudo-Meigs Syndrome consists of the presence of ascites, hydrothorax, benign ovarian cysts; the symptoms are resolved with the removal of the benign tumor. 18 This syndrome usually occurs in 5% of the Struma ovarii.…”

“…It constitutes 0.3-2.5% of ovarian teratomas and about 0.3% of all neoplasms of ovarian origin. 1,2 Originally described by Bottlin in 1888; later in 1903 Ludwig Pick who suggested that it represents a teratoma in which the thyroid tissue has grown more than the other elements. 3 It is defined as ovarian goiter comprising total or predominantly thyroid tissue (> 50%), in which the thyroid tissue has coated the other tissues or only the thyroid tissue has developed.…”
