In addition, patients often have a history of occlusive glove or footwear use. Further predisposing factors include pressure and friction from ill-fitting shoes or thin soles. Many patients have a history of psychoneurosis. In a subset of patients, there may be a family history of symmetrical lividity.
This condition has been subdivided into 2 forms:
- Transient symmetrical lividity – induced by various forms of physical or psychological stress along with the use of occlusive footwear; can be successfully treated with drying agents
- Persistent (chronic) symmetrical lividity – possibly familial; unresponsive to drying agents but with partial response to tretinoin cream
