Cutaneous vascular lesions have long been a source of puzzlement to both clinicians and pathologists. There is no well-accepted classification scheme; many lesions are so rare that only a handful of experts have experience with them; and in the case of some tumors, the basic question of "benign vs malignant" has required decades to answer.
Pathology of Vascular Skin Lesions goes a long way toward addressing all these problems. Both Sangüeza and Requena are acknowledged as belonging to the inner circle of vascular tumor experts. They have shown courage in proposing a new method of classifying vascular skin lesions. I happen to agree with most of their decisions; those who disagree can simply be asked, "Where is your classification scheme and convince me that it is better." I doubt if anyone will step forward with a more workable approach. After a brief but authoritative introduction, the authors systematically explore the topics of hamartomas, malformations, dilation of existing vessels, hyperplasias, benign tumors, and malignant tumors.
