Over 90 cases of sclerosing stromal tumor of the ovary (SST) have been reported in the English-language literature, but these authors did not mention the cytologic examination of SST. In 2 patients with SST, we were able to collect specimens for tumor imprint cytology. The number of cells in the specimens was extremely small. Two types of benign cells were observed against a clean background, comprising cells with round nuclei surrounded by abundant cytoplasm and cells with spindle-shaped or oval nuclei that had scanty cytoplasm. Our present findings suggest that intraoperative imprint cytology was able to rule out cancer. Considering that SST most commonly occurs in young women requiring conservative treatment, imprint cytology seems to have a potential diagnostic significance.
