Update on the classification of hemangioma

Area of Science:

• Vascular Biology
• Medical Terminology
• Congenital Anomalies

Background:

• Mulliken and Glowacki's 1982 classification of congenital vascular tumors and malformations has not resolved terminological confusion.
• The terms 'hemangioma' and 'vascular malformation' are often used interchangeably, despite distinct biological differences.
• Analysis of scientific literature reveals ongoing inappropriate use of terms for vascular lesions.

Purpose of the Study:

• To highlight the persistent confusion in terminology for vascular tumors and malformations.
• To emphasize the importance of differentiating true neoplasms (hemangiomas) from developmental defects (vascular malformations).
• To advocate for adherence to standardized classifications like the International Society for the Study of Vascular Anomalies (ISSVA) classification.

Main Methods:

• Review of scientific articles and medical textbooks.
• Analysis of the application of established classification systems for vascular anomalies.
• Comparison of terminology used for vascular lesions.

Main Results:

• Significant confusion remains regarding the classification and terminology of vascular tumors and malformations.
• Hemangiomas (neoplasms) are frequently misidentified as vascular malformations (morphogenesis defects).
• The ISSVA classification effectively distinguishes between proliferative endothelial lesions and structural anomalies.

Conclusions:

• Accurate terminology is essential for clear communication regarding vascular lesions.
• Adherence to standardized classifications like ISSVA is critical for appropriate management.
• Correctly identifying vascular lesions impacts therapeutic guidelines, patient management, and follow-up strategies.
