  1. 1.Callus

    A callus is a hard, thick layer of skin that develops when the skin experiences lots of friction and pressure. A callus may cause discomfort, but is of no big concern.

    Should go away immediately by trimming excess skin, and will not reappear if shoe inserts are used.

    Rarity:

  2. 2.Acromegaly

    Acromegaly is an uncommon condition where the body makes too much growth hormone, which is a hormone made by the pituitary gland that stimulates growth and repair of various body tissues. In most cases the excess hormone comes from a small non-cancerous growth in the pituitary gland.

    Surgery is effective in returning hormone levels to normal, but body abnormalities will remain for life.

    Dupuytren Disease, also known as Dupuytren's contracture, is a condition that gradually causes connective tissue (fascia) under the skin of the palm to thicken and become scar-like. Although Dupuytren's isn't painful, it does restrict movement. The thickened tissue forces several fingers - usually the ring and pinky fingers - to curl in toward the palm.
