Satoyoshi syndrome is a rare, multisystemic autoimmune disease mainly characterized by intermittent painful muscle spasms, alopecia (totalis or universalis in most cases) and long-lasting diarrhea that could lead to malnutrition, growth retardation, and amenorrhea. Secondary bone deformities and various endocrine anomalies may also be associated. Antinuclear antibodies are reported in many cases.
