Blue-colored sweating: four infants with apocrine chromhidrosis.

Apocrine chromhidrosis is a very rare, idiopathic disorder of the sweat glands characterized by the secretion of colored sweat. Because hormonal induction increases sweating, the symptoms of apocrine chromhidrosis usually begin after puberty. Although treatment may not be necessary in some cases, capsaicin cream and 20% aluminum chloride hexahydrate solution have been successfully used to treat patients requiring intervention. Here we report four cases with apocrine chromhidrosis. To the best of our knowledge, our patients are the youngest cases reported in the literature.
