Reflex sympathetic dystrophy: Occurrence of chronic edema and nonimmune bullous skin lesions
1993
Background: Reflex sympathetic dystrophy (RSD) is a poorly understood syndrome of post-traumatic pain, autonomic dysfunction, and progressive tissue atrophy, Classical descriptions of the cutaneous manifestations of RSD are usually limited to skin atrophy, vascular instability, and hyperhidrosis. Objective: Our objective was to further delineate the cutaneous changes in RSD. Methods: We have observed RSD-related inflammatory and bullous lesions in nine patients with active RSD. Results: Eight patients had significant edema of involved skin, two patients had evidence of a pigmented purpura-like inflammatory dermatitis, and two other patients had bullae on involved skin, Ultrastructural studies on a biopsy specimen from one patient with recurrent bullae revealed a disrupted basement membrane and abnormal anchoring fibrils. Conclusion: Skin disease in RSD is more diverse than commonly appreciated and includes severe edema, inflammatory lesions, and a nonimmune bullous eruption.
