Overview
The history, progression, and complications of pruritus are diverse and based on the cause.
Natural History
In patients with malignancies, pruritus could be the first sign. In allergic reactions, pruritus may be one of the hallmark features. Pruritus after hot baths is a finding associated with hematologic malignancies.
Complications
Secondary bacterial infections can occur when bacteria are introduced through breaks in the skin brought about by scratching. Lichenification, the thickening of skin as a result of chronic scratching, can also be seen [1].
Prognosis
Pruritus by itself never has a poor prognosis besides its effects on comfort and mental health. However, the underlying causes of pruritus have diverse prognoses, with malignancies being the poorest. Skin irritations such as with poison ivy often produce no lasting effects once treated.
