Signs and Symptoms
The most common locations for pitted keratolysis include:
  • Pressure-bearing sites on the soles of the feet, especially the heels
  • Non-pressure-bearing sites on the soles of the feet
  • Palms of the hands
In these areas, the condition appears as white patches studded with small (0.5–5 mm), shallow pits in the superficial skin. These pits can sometimes join together (coalesce) to form larger, crater-like lesions.

Pitted keratolysis may occasionally be itchy or painful. The foot odor often associated with pitted keratolysis may be socially embarrassing.
