REACTIVE CONDITIONS (note all of these can be "purple plums" clinically)

•pyogenic granuloma
•bacillary angiomatosis
•angiolymphoid hyperplasia with eosinophilia

 

DEVELOPMENTAL ABNORMALITIES

•nevus flammeus
•Sturge-Weber syndrome*
•Klippel-Trenany-Weber syndrome*
•Cobb syndrome*
•angiokeratoma
•lymphangioma circumscriptum

 

BENIGN TUMORS

•capillary hemangioma
•strawberry nevus
•cherry angioma
•Neonatal Hemangiomatosis*
•cavernous hemangioma
•Mafucci syndrome*
•Blue-Rubber-Bleb nevus syndrome*

 

 

 

*these syndromes are sporadic (i.e. not inherited)

 

 

 

Hemangioma:benign self-limited neoplasm of vascular endothelium (hypercellularity) with proliferative and involutional phases  

Port wine stain: not a neoplasm; a vascular malformation

vascular malformation: permanent structural anomalies made of capillaries, veins, arteries, or lymphatic vessels

Lymphangioma: not a neoplasm; a vascular malformation
