Stretch Marks in the Armpit

Stretch marks in the armpit. Stretch marks or striae in the armpit. Striae are usually associated with rapid weight gain, muscular growth or pregnancy. The location depicted here suggests an adverse effect caused by long-term use of a potent corticosteroid ointment as one differential diagnostic option. Fresh striae are reddish and gradually become more light-coloured.
