title: A curious case of blue-green discoloration in a middle-aged indian man: Chromhidrosis.
abstract: BACKGROUND
  Chromhidrosis is a rare sweat gland disorder characterized by the excretion of colored sweat. It can be classified as apocrine, true eccrine, and pseudochromhidrosis. Amongst the different types of chromhidrosis, green chromhidrosis is extremely rare. We describe herein a case of blue green chromhidrosis induced by ingestion of homeopathic medicine.
  
  
  METHODS
  A middle aged man presented to us with blue green discoloration of hands and feet. There was a preceding history of ingestion of homeopathic medication. Histopathology from the involved skin showed greenish particles within eccrine glands. Initial blood copper level was high which returned to normal level after discontinuation of the homeopathic medicine. Spectrophotometry revealed high copper content of the green sweat.
  
  
  CONCLUSIONS
  Our case emphasizes the importance of considering any type of ingested medicine, including homeopathic medicine, as a probable cause of chromhidrosis.
