A Case of Progressive Acquired Lymphangioma / 대한피부과학회지

ABSTRACT

Acquired progressive lymphangioma is a benign lymphatic proliferation characterized clinically by gradually enlarging erythematous patches and histopathologically by dermal vascular channels with "dissection of collagen" appearance. A 30-year-old woman presented a 6x4cm sized, erythematous patch on the right thigh, which had been gradually enlarging for 10 years since she had had a burn injury on the same site. Histopathologic findints of the lesion showed vascutar channels forming a network in the dermis with a "dissection of collagen" appearance. The cells lining the channels were stained with antibodies against muscle actin, factor VIII-related antigen, Ulex europaeus agglutinin I, CD34, and CD31. We made a diagnosis of acquired progressive lymphangioma and have been observing the course of the disease without specific treatment.
