Cutaneous Lymphangioma Circumscriptum Occurred Seven Years after Surgery with Soft Tissue Cystic Lymphangioma.

Lymphangiomas are rare benign congenital lymphatic malformations. They can be divided into three groups: cutaneous lymphangioma circumscriptum (CLC), cavernous, and cystic. CLC is the most common type, and rarely occurs with cavernous or cystic lymphangioma under the lesion. Here, we describe the case of a 9-year-old girl who presented with an asymptomatic vesicular lesion on her back. She was finally diagnosed with CLC by clinical manifestations, dermoscopic findings, and histologic findings. Seven years ago, there was a history of surgical operation in the department of general surgery, and the surgery was soft tissue cystic lymphangioma removal surgery. There was no skin lesion for seven years after surgery, but one occurred a month ago. Herein, we present a case of CLC that occurred after a long interval after surgery for soft tissue cystic lymphangioma.
