Uterus

This chapter is an overview of frequently used markers in the differential diagnosis of both common and less common tumors of the uterine cervix and corpus, with a focus on the effective markers employed to differentiate ade­nocarcinoma of the endocervix versus endometrium, low- grade versus high-grade endometrial neoplasms, benign versus malignant mimics of cervical and endometrial lesions. Other useful panels in the differential diagnosis of undiffer­entiated tumors of the uterine corpus and gestational tropho­blastic lesions in addition to the less common carcinomas of the cervix are also addressed. There are 47 tables in this chapter with immunohistochemical markers answering ques­tions that may arise when examining hematoxylin and eosin- stained sections. A summary of useful and frequently used markers with potential pitfalls is also provided. The effective diagnostic panels of antibodies for several entities are high­lighted in several tables.
