Toxic epidermal necrolysis is a life-threatening skin disorder, and its mortality rate is estimated to be approximately 20-30%. It is characterized that more than 30% of the skin surface is eroded, however, skin lesions are usually re-epithelialized within 2-3 weeks. Previously, we reported a fatal case of toxic epidermal necrolysis with hyperbilirubinemia, and more than 60% of body surface areas had been eroded for 9 weeks. ⋯ In this case, we had an opportunity to treat another case of toxic epidermal necrolysis with severe hyperbilirubinemia. In order to reduce serum bilirubin levels, we performed bilirubin adsorption therapies, and skin lesions were successfully re-epithelialized within 4 weeks. Though further studies are required, we considered that bilirubin adsorption therapies are worth trying for toxic epidermal necrolysis with hyperbilirubinemia, especially for the cases suffering from delayed re-epithelialization.

Multicenter Study Clinical Trial
Efficacy and safety of topical tacrolimus for the treatment of face and neck vitiligo.
Vitiligo is a common acquired idiopathic hypomelanotic disorder characterized by circumscribed depigmented maculae. The conventional treatments are limited by their inconsistent and incomplete responses, relapse rate, inconvenience to apply, side-effects and especially long-term effects. The aim of the present study was to determine the efficacy and safety of topical tacrolimus as monotherapy for the treatment of face/neck vitiligo in Taiwan. ⋯ All the reported adverse events were mild and similar to the well-known adverse effect of tacrolimus in the treatment of atopic dermatitis. Tacrolimus ointment is effective and well tolerated for the treatment of patients with vitiligo in Taiwan. It will be another drug of choice for persons with vitiligo who are unable to receive regular phototherapy and fear the side-effects of topical steroid in long-term use.

Review Case Reports
Pyoderma gangrenosum on the breast: a case presentation and review of the published work.
We present a case of pyoderma gangrenosum localized on the breast, without a preceding surgical intervention and associated systemic disorder. The ulcer had rapidly developed and covered a large portion of the breast. The patient responded well to systemic steroids and salicylazosulfapyridine and the ulcer completely healed with scarring after 3 months of treatment. ⋯ Though an unusual site for pyoderma gangrenosum, lesions on the breast showed the characteristic clinical features of the disease. The types of associated disorders were also similar to those of the cases with classical pyoderma gangrenosum. As most of the lesions healed with significant scarring, early recognition and treatment of pyoderma gangrenosum located on the breast is important to prevent serious physical and psychological morbidity.

A 73-year-old woman developed linear erythema at the sites of scratching-induced scars on the bilateral thighs 2 weeks before the initial consultation. Subsequently, edematous erythema developed in the upper eyelids, dorsum of the nose and the face, and pitting edema in the dorsum of the bilateral hands and feet. The C-reactive protein (CRP) level was 8.2 mg/dL and erythrocyte sedimentation rate (ESR) 121 mm/h. ⋯ However, because the joint swelling and pitting edema did not improve, p.o. administration of prednisolone (20 mg/day) was initiated. The CRP and ESR levels normalized 2 months after the initiation of administration, and pitting edema disappeared after 3 months. We report this case because linear erythema like that observed in dermatomyositis has not been described as eruptions associated with RS3PE.
