Lesions of the Lower Uterine Segment.

Background: The lower uterine segment (LUS) may become involved in cervical and endometrial lesions. In addition, some lesions are unique to the LUS, and identifying carcinomas in this region may have prognostic significance. Objectives: The aim of this review is provide useful coverage of the scope of lesions affecting the LUS. Methods: A Medline® search was conducted, using the term . Reported lesions of the LUS were reviewed. Results: Adenocarcinomas arising in the LUS can be associated with Lynch syndrome. Endometrial adenocarcinoma spreading to the LUS may indicate an increased risk of lymph-nodal involvement. Endometrial carcinomas arising from-as well as spreading to-the LUS may have prognostic significance. Conclusions: Understanding the scope of LUS lesions, as presented in this review, will assist in developing a differential diagnosis if a patient with such a lesion is encountered.
