In medicine, a vegetation is an abnormal growth [1] named for its similarity to natural vegetation. Vegetations are often associated with endocarditis. [2] [3] [4] They can be made of fibrin [5] and platelets. [6]

Types

Certain conditions are associated with specific vegetation patterns:

ConditionSizeInfective?

Rheumatic fever related to Streptococcus pyogenes Typically small
Libman–Sacks endocarditis related to systemic lupus erythematosus SmallNo (sterile)
Nonbacterial thrombotic endocarditis (NBTE)SmallNo (sterile)
