The sensitivity of frozen-section diagnosis of LMP and malignant mucinous tumors was low. The inaccuracy of a frozen-section diagnosis of ovarian mucinous tumors may be related to a tumor size of greater than 13 cm. Increasing the number of intraoperative samples over 3 sections per case may not effectively increase the accuracy of frozen-section diagnosis in mucinous tumors.

International Federation of Gynecology and Obstetrics stage, age at diagnosis, and deep stromal invasion were important prognostic factors for CSS in patients with SNEC. Adjuvant chemotherapy may provide survival benefits in surgically treated patients with early-stage SNEC.

The sonographic feature of intracystic floating echogenic balls is probably pathognomonic for mature teratoma and is easily detected in most cases. Color Doppler sonography is helpful in differentiating these benign nodules (small balls) from malignant tumors.

The objective of this series was to describe a simple rule for prenatal diagnosis of total anomalous pulmonary venous return (TAPVR). Fourteen fetuses had a prenatal diagnosis of TAPVR by the simple rule, including the following components: (1) the major criterion, which was the absence of a connection between the pulmonary vein and the left atrium; and (2) at least 1 of the following minor criteria: (a) the presence of a vascular confluence behind the atria, (b) abnormal spectral Doppler waveforms in the pulmonary veins, (c) a smooth posterior wall of the left atrium, (d) increased retroatrial space, (e) a dilated coronary sinus (cardiac type), (f) a dilated superior vena cava or brachiocephalic vein, and (g) an additional vessel on the 3-vessel/3-vessel and trachea view or a vertical descending vein. All were accurately diagnosed, and none were missed by the diagnosis. In summary, the simple rule described is helpful in increasing the number of accurate prenatal diagnoses of TAPVR.
