Quiz 9 Context:
A 77-year-old woman presents to her primary care physician for evaluation of joint pain. She has a longstanding history of osteoarthritis of the hands and wrists, which limits her activities.
The patient's medical history is significant for obesity, diabetes mellitus, and chronic obstructive pulmonary disease with frequent bouts of bronchitis, for which she often takes antibiotics and steroids.
During the physical exam, areas of cutaneous changes are noted on the chest wall, located in the skin folds beneath the breasts. The skin in this area is noted to be moist, tender to touch, with areas of erythematous plaques with an irregular border. There are also areas of small papules visible in the immediate periphery of the rash.
The skin finding is pictured right.
