pound weight gain in the last two years. Her past medical history is
unremarkable. She is not taking any medications. She does not smoke cigarette
nor drink alcohol. She has a sister who was recently diagnosed with left breast
invasive ductal carcinoma. Physical examination reveals a full moon face, a
humped neck, abdominal obesity and moderate hirsutism. She has red striae on
abdomen and legs. A few light brown macules are seen on her face and chest.
Laboratory tests reveal an afternoon cortisol level at 28 microgram/dl (normal
2-18 microgram/dl) and an ACTH level at 5.6 pg/ml (normal 10-50pg/ml).
