Detailed answer

Dark spots can be a sign of certain autoimmune conditions. Conditions such as systemic lupus erythematosus (SLE) or dermatomyositis can cause hyperpigmentation or dark patches on the skin. In these autoimmune conditions, the immune system mistakenly attacks healthy cells, which can lead to inflammation and subsequent skin discoloration. It is important to consult with a healthcare professional for proper diagnosis and management of any skin concerns.
