If you tried trimming a callus at home, or even just picked at it a little bit and noticed a little pearl/rock fall out of it, this is likely the core of a porokeratosis.  When callus material builds up near or into a sweat gland, it can have the appearance of a small pebble once it loosens and falls out (which doesn’t always happen). 

To see if you have a porokeratosis and to get treatment, please contact our office for an appointment today!
