A case of generalized red sweating.

We report a case of a 70-year-old man with a 5-year history of red pigmented sweating on the axillae, groin, forearms, trunk, and and peri-nuchal sites. No identifiable cause of the pigmented sweat was identified. Biopsy revealed lipofuscin pigment leading to the diagnosis of idiopathic chromhidrosis. This case represents an unusual presentation of chromhidrosis that was not limited to the apocrine sweat gland distribution and ultimately revealed no identifiable cause. After failing multiple treatment options, the patient elected for a trial of treatment with 20% aluminum chloride solution.
