We report a case of herpes zoster with thermographic follow-up. This case revealed a correlation of thermal image with intensity of pain. A thermogram might be used as an objective assessment tool of subjective pain symptoms in herpes zoster.
A 39-year-old Korean man reported dysesthesia of the left axilla. Two days later (day 0 [D0]), a pruritic urticarial plaque was noted on the left side of the chest. One day later (D1), tiny vesicles began to develop, and pain became evident. On the next day (D2), skin lesions appeared on the back, and the first thermogram was performed (Figure 1). From then on, the lesions were followed up by thermogram (IRIS-5000; Medicore, Seoul, South Korea) during the course of this mild herpes zoster eruption. In addition, the severity of pain was assessed by the visual analog scale (VAS), and gross findings were followed-up by photographs. We measured temperature differences between the lesions and contralateral normal skin (ΔTs) by thermography.
