Endovenous laser ablation with a 1,320-nm laser in combination with foam sclerotherapy and phlebectomy as appropriate is effective treatment of chronic venous ulcers and should be considered as a treatment option for patients with C6 venous insufficiency. To the authors' knowledge, this is the largest, prospective series of chronic venous ulcers treated with EVLA. Further randomized controlled studies are needed to confirm these findings.

Background Basal cell carcinoma (BCC) is a common tumor but rarely presents on nonexposed skin. We sought to identify and characterize the traits of the malignancy over a 10-year period.Methods A retrospective chart review of all BCCs between 2007 and 2017 was performed. Clinical characteristics and histological features were evaluated.Results Of all BCCs biopsied in a 10-year period, 53 tumors in 50 patients were diagnosed in the groin or buttocks. This accounts for 0.094% of all BCCs during this time period. None of the cases had genetic diseases prone to skin cancer development or were immunosuppressed. The most common location was the buttocks, and the most frequently diagnosed histological subtype was nodular (49%).Conclusion To our knowledge, this is the largest report of BCC of the groin and buttocks.In this rare presentation of a common tumor, the histological characteristics of it are not more aggressive than other sites on the body.
