Somatization disorders in dermatology.

This paper reviews a wide range of somatization-related symptoms that are encountered in dermatology. These include the unexplained cutaneous sensory syndromes especially the cutaneous dysesthesias associated with pain, numbness and pruritus; traumatic memories in post-traumatic stress disorder (PTSD) which are experienced on a sensory level as 'body memories' and may present as local or generalized pruritic states, urticaria and angioedema; and unexplained flushing reactions and profuse perspiration, in addition to unexplained exacerbations of stress-reactive dermatoses such as psoriasis and atopic eczema secondary to the autonomic hyperarousal in PTSD; classic 'pseudoneurologic' symptoms associated with dissociation including unexplained loss of touch or pain, in addition to the self-induced dermatoses such as dermatitis artefacta and trichotillomania that are encountered with dissociative states; and body dysmorphic disorder where the patient often presents with a somatic preoccupation involving the skin or hair.
