Dermoscopic-Histopathologic Correlation of Cutaneous Lymphangioma Circumscriptum

Abstract

C LINICALLY, CUTANEOUS LYMPHANGIOMA circumscriptum (CLC) (Figure 1A and Figure2A) should be differentiated from other vascular and lymphatic lesions, such as hemangiomas, angiokeratomas, lymphangioendotheliomas, and angiosarcomas, as well as from warts, molluscum contagiosum, condyloma acuminata, and hidrocystoma. The dermoscopic features of CLC demonstrate 2 distinct patterns: (1) yellow lacunae surrounded by pale septa without inclusion of blood (Figure 1B) and (2) yellow to pink lacunae alternating with dark-red or bluish lacunae due to the inclusion of blood (Figure 2B). In pattern 2, the blood cells precipitate, giving rise to 2-tone lacunae.
