The classification and characteristics of tumors and tumor-like lesions of the female lower genital tract have remained relatively constant over the years, though shifts in nomenclature have occurred, and a comprehensive review of the diverse histomorphology and differential diagnosis of lesions at these sites is of paramount importance. Although female lower genital tract pathology is largely dominated by epithelial tumors, the pathologist will also encounter mesenchymal, melanocytic, and hematopoietic neoplasms. This fascicle provides a comprehensive discussion of these categories with emphasis on their wid¬ening clinical and pathologic spectrum as well as their evolving molecular landscape. The book conveys the authors’ extensive experience as pathologists devoted to women’s health and to ad¬vancing understanding of gynecologic disease.
