Verrucae, Corns, and Calluses
It’s easy to get confused about the differences between a corn and a verruca. It’s a wise idea to ask a professional to determine which one you have. As a general rule, a corn is more commonly seen among children and young adults. A verruca has the appearance of numerous black pin-hole spots. The black spots are tiny capillaries that have pinched up in the skin formation and do not have the normal skin striations running through them. A verruca is painful when pinched, while a corn is painful when pressed directly.
Calluses are localised areas of hard skin. Corns, on the other hand, have a centralised area of hard skin with a nucleus and are formed when pressure is applied to a bony prominence. Calluses are caused by rubbing or sheering pressures – the result of ill-fitting shoes, or uneven pressure when walking
