Background. Patients with epithelial ovarian cancer have a high risk of (non-)melanoma skin cancer. The association between histological variants of primary ovarian cancer and skin cancer is poorly documented. Objectives. To further evaluate the risk of skin cancer based on the histology of the epithelial ovarian cancer. Methods. A cross-sectional study within a large population-based dataset. Results. Skin cancer was found in 2.7% (95% CI: 2.3–3.1) of the 5366 individuals forming our dataset. The odds ratio (OR) for endometrioid cancer in the ovary to skin cancer in the under 50 age group was 8.9 (95% CI: 3.2–25.0). The OR decreased in older patients to 1.2. Conclusions. Patients with epithelial ovarian malignancies show an increased risk of skin cancer. A significantly increased risk (4.3%) for endometrioid ovarian cancer was found in the group aged under 50.
