Definition / general
- Very common; rapidly growing polypoid red mass surrounded by thickened epidermis, often in finger or lips
- Also called granuloma pyogenicum, lobular capillary hemangioma
- May be associated with keratinous cyst
- Benign, often regresses spontaneously
- May be disseminated, occur within port wine stains, be in deep dermis / subcutis or be intravenous
Variants:
- Classic polypoid, dermal, subcutaneous, intravenous, eruptive, with multiple satellites

Pyogenic granuloma
Gross description
- Fleshy cutaneous tumor
Microscopic (histologic) description
- Lobular pattern of vascular proliferation with inflammation and edema resembling granulation tissue
- Thin epidermis at top with variable ulceration
- Acanthosis and hyperkeratosis at sides
- Central branching vessel is called capillary or vascular lobule, with no / rare red blood cells, surrounded by endothelial cells
- Variable mitotic activity
- Deep lesions often lack edema and inflammation
