low-magnification micrograph (A)and is from the same organ as the high-
magnification micrograph (B).
A 30-year-old woman presents with chronic fatigue that has worsened
during the past months. She has muscle weakness and describes a loss of
appetite with a 15-lb weight loss since her last visit. She admits to having
“no appetite and eating less,” but “craves salty foods” when she is able to
eat. She is nauseous much of the time and sometimes vomits after eating.
Her bowel movements are loose with frequent diarrhea. Her blood pres-
sure is low and she becomes dizzy when standing. It is the middle of win-
ter in Kansas and she has a healthy tan. The darkening of her skin is most
visible in her skin folds and at her elbows, knees and knuckles. She
describes being “irritable and depressed” and has had very irregular men-
strual periods over the 6 months, which she attributes to early menopause.
However, she reports no“hot flashes.” Which of the following would
occur in the regions of a biopsy specimen labeled in the accompanying
