TLDR Patients with alopecia areata should be checked for muscle spasms, diarrhea, and ANA to avoid missing Satoyoshi syndrome.
Satoyoshi syndrome, an autoimmune disorder affecting mainly girls and young women, was characterized by alopecia, muscle spasms, and diarrhea, with 60% of patients showing antinuclear antibodies (ANA). Trichoscopy revealed yellow dots similar to alopecia areata, leading to potential misdiagnosis. The study proposed diagnostic criteria and identified two subtypes: ANA-positive, which responded well to glucocorticosteroids, and ANA-negative, with a poorer prognosis. It recommended that patients with alopecia areata, especially alopecia totalis, be evaluated for muscle spasms, diarrhea, and ANA to avoid missing Satoyoshi syndrome.
