borderline ovarian tumor
Also written as: BOT — Borderline Ovarian Tumor
Low-grade epithelial ovarian neoplasm with malignant potential but lacking stromal invasion.
Full Definition
Borderline ovarian tumors (BOTs), also known as tumors of low malignant potential, are epithelial ovarian neoplasms that exhibit features between benign cystadenomas and invasive carcinomas. They are characterized by epithelial proliferation, nuclear atypia, and mitotic activity but lack destructive stromal invasion. BOTs typically have an excellent prognosis but require long-term surveillance due to potential for recurrence or progression to invasive carcinoma.
Usage
Usage note: Also acceptable: tumor of low malignant potential (LMP).
