Hyperpigmentation of the skin and oral mucosa is a characteristic feature of primary Addison's disease. This is due to increased levels of adrenocorticotropic hormone (ACTH) which stimulates melanin production in the skin. Enlargement of the liver and spleen is not a specific feature of primary Addison's disease. Kidney failure is not directly associated with Addison's disease. Hypopigmentation would be unlikely since excessive ACTH levels would stimulate melanin production, causing hyperpigmentation instead.
