Osteoarthritis progresses further with obliteration of the joint space. The appearance of subchondral cysts (cysts in the bone underneath the cartilage) indicates the erosive phase of disease progression in osteoarthritis.
Keratosis pilaris is a common and harmless condition where the skin becomes rough and bumpy, as if covered in permanent goose pimples.
Keratosis pilaris occurs when the human body produces excess amounts of the skin protein keratin, resulting in the formation of small, raised bumps in the skin often with surrounding redness. The excess keratin, which is the color of the person's natural skin tone, surrounds and entraps the hair follicles in the pore.
