Thoracic "Frog Roe" With Zosteriform Distribution

Abstract

A 13-year-old female patient was referred to our department for a thoracic lesion present since birth. The physical examination reveals grouped vesicles with clear and hematic content similar to "frog roe", with a subcutaneous component and a zosteriform distribution (Figure 1A). She referred episodes of pain and increased soft tissue associated for a few months ago. The polarized light dermoscopy showed pink lacunae divided by white septa and polymorphic vessels.Besides, the "hypopyon sign" was shown inside the lacunae (Figure 1B). The magnetic resonance imaging study reported mixed veno-lymphatic vascular malformation.
