In this chapter we will review the anatomy and traumatic injuries of the perineum, external genital organs and the breast, both sexual and nonsexual in origin.  Although the breasts anatomically are not part of the perineum or the external genital organs, it is considered an accessory to reproduction function.  Also, when considering traumatic injuries to the breasts, especially those of a sexual abuse nature, they are not uncommonly subjected to trauma as are the external genitalia.

As in previous chapters the first part, pages 1 – 141, will cover the relevant anatomy of the perineum, external genital organs and the breasts.  The remaining portion of the chapter, pages 142 – 416, are devoted to traumatic injuries to these structures.  The purpose of this format is two fold: first, it will constitute a review of the anatomy of these structures for medical students, pathology residents, forensic pathology fellows, forensic nurses, emergency room residents and trauma residents, aiding them in understanding the pathophysiologic dynamics of traumatic injuries; secondly, since this educational blog may also be used by medicolegal investigators, emergency medical technicians, paramedics, law enforcement personnel and attorneys, such a review will help them to develop a better understanding of the effects of trauma on the victims.

As indicated above, there will be a discussion of traumatic sexual abuse injuries, which will include male and female, adults, elderly, children and infants.  Due to the nature of this subject the illustrations are graphic, which some may find disturbing to view.

Lastly, there will be a section addressing various pragmatic issues , which the forensic pathologist may face as a medical examiner/coroner
