Scaly Skin and Ichthyosis
Probably everybody at some point notices some flakes – some scales – on their skin. Maybe some dry patches on the lower legs? Or the peeling that happens after a sunburn. But most of the time our skin – if it is healthy – doesn’t produce visible scales or flakes. Instead we shed our skin invisibly, single invisible cell by single invisible cell.
But some people are born with a condition in which visible scales accumulate on most or all of their skin surface. This condition, called ‘ichthyosis‘, we now recognize is not just one thing, but instead represents a whole family of inherited conditions that have this feature in common.
