Abstract
Lymphangioma circumscriptum is a rare lymphatic malformation that involves the skin and may extend to subcutaneous tissue and muscle. It usually presents as grouped micro- to macroscopic vesicles filled with lymph. Surgical excision has been the standard treatment, but it is associated with scarring, infection, injury to the surrounding structures, and a high recurrence rate. Herein, we report a 24-year-old male patient with a lymphangioma circumscriptum on the nape of the neck that was treated with two sessions of an intralesional injection of 1% sodium tetradecyl sulfate sclerotherapy with a very good result. After this treatment, there was no more discharge and a reduction in the lesion's size by 70%. Sclerotherapy using sodium tetradecyl sulfate can be considered a successful minimally invasive treatment option for lymphangioma circumscriptum.
