Psoriasis on the breast is uncommon, but it can occur. If it does, it most often involves the breast skin rather than the nipple and areola. Psoriasis can have different appearances in different parts of the body, as well as among different individuals.
This is an example of psoriasis on the breast (biopsied to confirm, given patient known history of psoriasis elsewhere on body) as well as in another patient example on leg.
