* Refer to UpToDate graphic on common causes of pseudochromhidrosis.
¶ Apocrine distribution consists of involvement of the axilla, areola, anogenital skin, and/or malar cheeks.
Δ In patients with apocrine chromhidrosis, Wood's lamp illumination of blue, green, or yellow sweat will demonstrate yellow fluorescence and confirms the diagnosis of apocrine chromhidrosis. Wood's lamp illumination is not reliable for apocrine chromhidrosis that manifests as darker sweat (black or brown).
