The most common vascular lesions in childhood are the hemangiomas of infancy and, in adulthood, the cherry angiomas. Hemangiomas and angiomas are benign proliferations of blood vessels and although they have different clinical behavior, they are described together because they share common dermoscopic features.
- Absence of melanocytic criteria
- Lacunae (also known as lagoons): well-demarcated, round to oval red, reddish-brown or reddish-blue areas that commonly vary in size and color within a given lesion. Lacunae may be either tightly clustered or loosely scattered throughout the lesion and they are often located on a background of red, red-blue, or red-white homogeneous color. No vascular structures are seen inside the lacunae.
- Occasionally, individual dilated blood vessels or a red network of vessels may be visible.
- Hemangiomas may develop a partial thrombosis, acquiring a focal blue-black color, or a total thrombosis manifesting a jet-black color.
