(a) To evaluate the efficacy and safety of narrow-band intense-pulsed light (DPL) in immediate post-operative scar. (b) To observe the process of scar formation under dermoscopy in the first 6 months. Nine patients with postoperative scars were enrolled in the randomized, prospective, split-scar study. Patients were treated in one half of the scar with DPL for cosmetic improvement at a wavelength of 500–600 nm and the other half was not treated as control. The laser treatments were initiated 2 weeks after the surgery and were given 3 times over a 4-week period. All patients were followed-up for 3 months from the last treatment. Photographs and dermoscopy digital images were collected each time. (a) Neither DPL or control produce statistically significant improvements in Vancouver Scar Scale. Moreover, comparatively, there was no statistical difference in Vancouver Scar Scale between DPL or control. However, 6 out of 9 patients treated with DPL had reduced scores in vascularity sooner compared with control. (b) Under dermoscopy, redness, and swelling were obvious from 2 weeks after surgery, but were gradually alleviated. The surface of the scar gradually became uneven and rough. DPL might be beneficial in early recovery of immediate post-operative scar. [ABSTRACT FROM AUTHOR]

Psoriasis is an immune‐mediated chronic inflammatory skin disease and chronic kidney disease is one of the common comorbidities of psoriasis. Ixekizumab, a humanized IgG4 monoclonal antibody, has been approved for the treatment of moderate‐to‐severe plaque psoriasis in recent years. However, ixekizumab has not been studied in a population of patients with renal insufficiency. We report two cases of plaque psoriasis patients with renal dysfunction successfully treated with ixekizumab without dose reduction，which experience no side effects and does not cause further kidney injury.

We report a case of cutaneous phaeohyphomycosis caused by Exophiala dermatitidis. An adult male presented with a 1 month history of erythematous swelling and ulcer on the right forearm. E. dermatitidis was identified from the lesion through microscopic examination, in vitro culture, cutaneous biopsy and molecular analysis. He was treated with oral itraconazole (400 mg/day) and showed improvement. [ABSTRACT FROM AUTHOR]
