Sclerosing stromal tumours of the ovary

Sclerosing stromal tumours of the ovary have recently been described as a histologically and clinically distinct subgroup within the thecoma‐fibroma spectrum of benign ovarian sex cord stromal tumours. Reported cases occurred predominantly in young women and only occasional tumours showed evidence of hormonal activity. The present series of five cases expands the spectra of both histological patterns and clinical presentations and suggests that the entity of sclerosing stromal tumours may not be as clearly circumscribed as has been previously reported.
