Nonneoplastic Lesions of the Ovary

Abstract

The World Health Organization (WHO) recognizes three general categories of invasive carcinoma of the cervix: squamous cell carcinoma, adenocarcinoma, and “other epithelial tumors” (Table 6.1 ) [278]. The “other epithelial tumors” include adenosquamous carcinoma, adenoid basal cell carcinoma, adenoid cystic carcinomas, as well as neuroendocrine tumors and undifferentiated carcinoma (Table 6.1 ) [278]. The relative frequency of these different tumor types varies between studies; in general, squamous cell carcinoma is the most common histologic subtype accounting for 70–80% of invasive carcinomas. Adenocarcinoma and adenosquamous carcinoma comprise 10–15% of all cases, and all others 10–15% [45, 245, 271].
