Pruritus without identifiable underlying disease, see also pruritus cum materia. In dermatology, this term is also incorrectly used for pruritus without recognizable skin changes in the case of underlying internal diseases. In fact, it is a diagnosis of exclusion that should only be made when all other causes have been ruled out. Idiopathic pruritus sine materia is often psychogenic. It is found in older, single, depressive personalities. Sebostatic pruritus must always be ruled out.
