Pustule. Like papules, pustules are small round lesions; unlike papules, they are clearly inflamed and contain visible pus. They may appear red at the base, with a yellowish or whitish center. Pustules do not commonly contain a great deal of bacteria; the inflammation is generally caused by chemical irritation from sebum components such as fatty free acids. Nodule or Cyst. Large and usually very painful, nodules are inflamed, pus-filled lesions lodged deep within the skin.
