Background The development of bullae accompanying acute oedema is a commonly observed clinical sign but has been rarely reported in the literature.
Objectives To document the clinical features and increase awareness of this entity.
Methods Retrospective case note review of 13 inpatient consultation cases seen in two dermatology departments.
Results Oedema blisters appear to be related to the speed of development rather than the degree of oedema, and respond rapidly to the reduction of the underlying oedema.
Conclusions Recognition of oedema blisters is important as they respond quickly and completely to treatment of the underlying oedema.
