What type of mastectomy is most likely to include a simple breast, nipple, and skin ellipse?

The type of mastectomy that most likely involves the removal of a simple breast, nipple, and an ellipse of skin is a skin-sparing simple mastectomy. This surgical approach preserves as much skin as possible while removing breast tissue and the nipple, which can be beneficial in cases where immediate breast reconstruction is planned.

In contrast, a prophylactic mastectomy is typically performed to prevent breast cancer in individuals at high risk, and while it may involve significant tissue removal, it does not specifically focus on preserving skin in the same way that a skin-sparing approach does. A radical mastectomy involves the removal of breast tissue, surrounding lymph nodes, and some chest wall muscle, making it more extensive and less focused on skin preservation. A modified radical mastectomy retains the chest wall muscles while removing breast tissue and lymph nodes, and though it may allow for some preservation of skin, it does not typically prioritize the skin ellipse as much as a skin-sparing simple mastectomy does.

Thus, the characteristic of including a simple breast, nipple, and skin ellipse aligns most closely with the intent and method of a skin-sparing simple mastectomy.
