Learning Objective
Describe the clinical features, common types, and behavior of benign vascular tumors of the skin.
Hemangiomas
- Definition: Benign vascular tumors of endothelial origin
- Clinical Appearance:
- Can be macular, plaque-like, or lobular
- Vary in size, color, and location
- Notes: Refer to the vascular pathology chapter for detailed histology and classification
Pyogenic Granulomas
- Definition: Misnomer; these are capillary hemangiomas, not true granulomas
- Etiology: Often develops after trauma
- Location: Skin and mucous membranes (commonly the mouth)
- Clinical Features:
- Well-demarcated, red or pink fleshy growths
- May ulcerate easily
- Behavior: Benign; may regress or be removed if symptomatic
Activity
High-Yield Points:
- Hemangiomas have varied morphology and are usually self-limited
- Pyogenic granulomas are rapidly growing, vascular, and often post-traumatic
