The article discusses ten cases of 'vasculitis-like' purpuric plaques with a necrotic center that appeared after follicular unit excision (FUE) hair transplantation surgery, a phenomenon not previously described in the literature. The patients, from five trichology and hair transplantation units in Spain, experienced lesions that clinically resembled leukocytoclastic vasculitis, but all resolved spontaneously within 14 days without complications. The histopathologic study ruled out vasculitis, suggesting that trauma to blood vessels during the FUE procedure or thermal damage may have caused the lesions. The authors emphasize the importance of accurate diagnosis by dermatologists to prevent unnecessary aggressive treatments for this benign and self-resolving condition. [Extracted from the article]

We describe 28 patients who experienced effluvium with previously unreported features shortly after hair transplant surgery. Notable features were as follows: a) a linear morphology; b) immediate onset (1-3 days); c) association with dense-pack grafting in areas of receding hairline at the temples (Mickey Mouse pattern); d) a progressive increase in the diameter of the hair loss line (wave-like pattern); e) in some cases, subsequent concentric linear effluvium on the crown (donut pattern); and f) other forms of previously unreported immediate-onset effluvium. The linear morphology could be the result of dense packing, which can cause perilesional hypoxia and loss of miniaturized hairs around the recipient area. Since linear hair loss can cause patient concern about graft failure, we recommend taking images of transplanted and nontransplanted areas immediately after surgery and warning patients in advance about these transient effects, which are fully reversed in 3 months., (Copyright © 2023 AEDV.

Introduction and Objectives: Electrochemotherapy is indicated for the treatment of unresectable cutaneous and subcutaneous tumors. The technique involves the synergistic use of electroporation of cell membranes to increase the cytotoxicity of anticancer drugs delivered to the tumor cells. The aim of this study was to analyze the clinical effectiveness and safety of electrochemotherapy in the treatment of unresectable locoregional recurrent or metastatic melanomas., Material and Methods: We studied 31 patients treated between January 2007 and December 2012. The European Standard Operating Procedures of Electrochemotherapy (ESOPE) were applied in all cases. Treatment response was analyzed as overall patient response (mean response based on results for all lesions treated in a given patient)., Results: Response was classified as partial in 49% of patients and complete in 23%. At 1 year, the level of response achieved had been maintained in 17 patients. Disease progression was observed in 28% of the series. Immediate local complications (pain, swelling, erythema) were mild and resolved within 48hours in most cases. Eight patients developed subsequent local complications, such as ulcers and secondary infections associated with necrosis of the lesions. These complications were brought under control with topical treatments., Conclusions: Electrochemotherapy is a very effective, safe, and efficient treatment for advanced locoregional disease in patients with unresectable melanoma lesions., (Copyright © 2014 Elsevier España, S.L.U. and AEDV.
