(a) Findings on the first examination: Redness and capillary dilatation were observed in the nose root region over the dorsum of the nose, indicated by the circle. (b) 1 year after surgery: Redness and capillary dilatation in the nose root region disappeared, indicated by the circle. (c) First examination at our hospital: Photograph of the sole. Pustules associated to scaling plaques and some fissures in the palmoplantar area were noted. (d) 1 year after surgery: Photograph of the sole. No recurrence of palmoplantar pustulosis was noted at 1 year after surgery. (e) MRI: A water-soluble implant remained in the region, indicated by the arrow. (f) 1 year after surgery: Postoperative reactions were noted in the region, indicated by the arrow.

Redness and the capillary dilatation were observed in the nose root region (Figure 1(a)). In addition, pustules associated with scaling plaques and some fissures in the palmoplantar area were noted (Figure 1(c)). T2W1 was noted in the nasal apex (Figure 1(e)). The patient reported an abnormality in the injection region at the nose root, but this was not observed. No recurrence of palmoplantar pustulosis was noted 1 year after surgery (Figure 1(d)). Redness and capillary dilatation of the nose root region spontaneously disappeared 1 year after surgery (Figure 1(b)). On imaging, a postoperative reaction was observed in the surgical region 1 year after surgery (Figure 1(f)).
Intraoperative findings. (a) A water-soluble specimen in the wound region, indicated by the arrow. (b) At the completion of debridement.

The wound region was filled with granulation tissue and a water-soluble implant (Figure 2(a)). After implant excision, the wound region was curetted, irrigated, and closed by suturing (Figure 2(b)). Methicillin-resistant coagulase-negative staphylococci (MRCNS) were detected in the culture of a fluid that leaked through the incision (Figure 2(a)).
Histopathological view of granulation tissue: Inflammatory cell infiltration was observed. Scale bar 200 microm.
