ABSTRACT: The skin is the largest organ in the human body, and as such, cutaneous problems constitute a common component of visits to medical professionals. The skin functions as a physiologic barrier and a major organ of homeostasis. The practicing obstetrician–gynecologist can play an important role in identifying skin diseases and initiating management. Additionally, the skin often reflects internal disease states. An astute health care provider can identify systemic conditions early, with the goal of improving management. This monograph reviews common cutaneous conditions, both benign and malignant, hair and nail disorders, and skin conditions unique to the adult woman.
