Clinicopathologic study of squamous cell carcinoma of the ovary

Clinicopathologic study was performed on 10 squamous cell carcinomas of the ovary. All four patients with stage II or III lesions had deteriorated within 1 year after the operation, and four of six patients with stage I lesions had survived over 5 years. Clinical findings of the patients with ovarian SCC, including age, chief complaint, clinical stage, and outcome of the patients, were similar to those of common epithelial cancer. The effectiveness of chemotherapy was not shown in this study. Histopathologic study revealed that squamous cell carcinoma may arise not only from epidermis, but also from squamous metaplastic epithelium of respiratory gland.
