A member asked:

White patches on left upper arm, no pain, had it for about 3 months. thought it was a tan but it's not.

A doctor has provided 1 answer

White patches: Depigmented areas of skin are seen as an aftermath of previous injuries or severe inflammation but in the absence of these factors, white patches are commonly caused by an autoimmune disorder known as vitiligo. A dermatologist could confirm the diagnosis and advise you.
