1. Cutaneous Vascular Anomalies By Dr. Ari Zangana

2. There are two main categories : - Hemangiomas - Vascular malformations

3. They are totally different biological entities has been confirmed by immunohistochemical, radiological, and hemodynamic studies.

4. Hemangiomas: Antenatal or postnatal endothelial proliferation

5. Hemangiomas: Grow rapidly during infancy, regress slowly during childhood, and never appear in adulthood.

6. Hemangiomas: - Proliferative phase. - Involutional phase.

7. Proliferative phase : - Hemangioma grow rapidly during 6-8 months reach the maximum size by the end of the first year. - Skin becomes elevated and red color.

8. Involutional phase: Color begins to pale and tumor fells less tense.

9. Hemangiomas: - Typically appear in the neonatal period. - Approximately 80% was a single tumor. - More common in female 3-5:1. - Incidence in white infant is 10%-20%. - Involution is complete in 50% of children by age 5 years. - Normal skin is restored in about 50%.

10. Clinical types of hemangiomas : New Terminology Old Terminology - Superficial - Capillary - deep -Strawberry

11. Vascular malformations: Are errors of embryonic development Usually obvious at birth Never regress and often expand

12. Vascular malformations : Subcategorized based on predominant channel type and flow characteristics: - Slow flow - Fast flow

13. Slow flow: - Capillary and telangiectases - Lymphatic malformation -Venous malformation

14. Fast flow: - Arterial malformation - Arteriovenous malformation

15. Vascular malformations: New terminology Old terminology Capillary Port wine Venous Cavernous Lymphatic Lymphangioma Cystic hygroma

16. Capillary Malformation

17. Venous Malformation

18. Arterial malformation
