Multiple smooth nodules and abscesses

A 36-year-old woman with a long history of cigarette smoking went to her dermatologist complaining of multiple smooth nodules and abscesses that had developed on intertriginous areas, including her underarms and the skin folds of her breasts. She noticed that they had appeared prior to her last period, healed with scarring, and then appeared again just before her most recent period. She thought maybe she just needed to lose weight to avoid her skin rubbing against itself and causing irritation.
