Wilson, Young Lee, and Babar Rao A 15-year-old Asian female presents to the emergency room due to a 4-month his- tory of increasing fatigue, nausea, and vomiting. She vomited between 3 and 12 times a day and displayed signs of dehydration due to her inability to tolerate oral intake. She also complained of a 12 lb weight loss despite no changes in diet and a sense of lightheadedness when she stands abruptly. She was diagnosed with alope- cia areata 2 years ago and was treated with monthly intralesional triamcinolone injections for 3 months. Physical examination of the scalp revealed three well-defined patches of hair loss without scarring. Further examination revealed hyperpigmentation of the area around the eyes, dorsa of the hands, palmar creases, buccal mucosa, oral cavity, and gingiva (Figs. 1.1 and 1.2). The patient reported this hyperpigmentation has wors- ened over the last year. Her temperature is 99.7 °F, pulse is 89/min, and blood pressure is 101/67 mmHg. Her pregnancy test came back negative, sodium level was 127 mEq/L, potassium was 5.6 mEql/L, thyroid-stimulating hormone was 4.2 μU/mL, AM cortisol was 1 μg/dL. Dermatology was consulted.
