[Discussion on pathological diagnosis of vascular diseases based on ISSVA classification]

Area of Science:

• Pathology
• Vascular Biology
• Oncology

Context:

• Accurate diagnosis of vascular lesions is crucial for effective treatment.
• Distinguishing between vascular tumors and malformations presents diagnostic challenges.
• The International Society for the Study of Vascular Anomalies (ISSVA) classification provides a framework for understanding these conditions.

Purpose:

• To clarify diagnostic criteria for vascular diseases based on the ISSVA classification.
• To emphasize the importance of endothelial cell proliferation in differentiating lesion types.
• To discuss pathological diagnostic issues related to vascular anomalies.

Summary:

• This article reviews the pathological diagnosis of vascular diseases, emphasizing the ISSVA classification.
• Key diagnostic features include assessing endothelial cell proliferation to differentiate hemangiomas from vascular malformations.
• The focus is on understanding the fundamental nature of the disease, not just lesion categorization.

Impact:

• Improved diagnostic accuracy for vascular anomalies.
• Enhanced understanding of the pathological basis of vascular tumors and malformations.
• Facilitation of standardized clinical practice in the study of vascular anomalies.
