Physical examination revealed firm swelling and erythema of the cheeks and forehead without any obvious scaling, papules, or pustules (Figure 1Aa-Ac). System (Canfield Scientific, NJ, USA), the erythema was more obvious (Figure 1Ad-Af). Sense of swelling and hyperalgesia were measured using a visual analog scale (VAS) and were 6.0 and 6.5 on a 10-point scale, respectively. Maintenance treatment was administered for a further 2 months, every 4 weeks, and then discontinued due to improvement in clinical manifestations without relapse at 6 months follow-up (Figure 1Ba-Bc, Ca-Cc, and Da-Dc) and a reduction in erythema intensity (Figure 1Bd-Bf, Cd-Cf, and Dd-Df).
(A) VAS score for swelling at the 6-month follow-up. (B) VAS score for hyperalgesia at the 6-month follow-up. (C) Facial erythema extent at the 6-month follow-up.
