A Case of Lymphangioma Circumscriptum Treated with Pulsed Dye Laser

Lymphangioma circumscriptum (LS) is a superficial lymphatic malformation which consists of dilated lymphatic channels. Clinically, it presents as grouped translucent vesicles, which usually contain clear lymph fluid but may also contain red blood cells due to hemorrhage. It has been suggested that pulsed dye laser (PDL), which efficacy is known in vascular lesions, has also been successfully used for such lympangiomas with hemorrhagic character. In the literature, two patients who had LS and whose lesions responded well to PDL treatment have been reported. Here, we describe a 14-year-old woman with LS who had vesicles on her left shoulder some of which showed hemorrhagic character and who gave an inadequate partial response to the treatment with PDL.
