"Knuckle pads, also known as Garrod pads, Garrod nodes or holoderma, are benign, subcutaneous, fibrofatty growths that overlie the interphalangeal joints of the fingers or toes 1,2. These are a rare form of superficial musculoskeletal fibromatoses."
"The aetiology is unknown and is usually considered idiopathic but there are associated with repetitive trauma (e.g. boxing, swimming, carpet laying), and other fibromatoses (e.g. Duputren disease, Peyronine disease, Ledderhose disease) 2,3,5."
"Knuckle pads present as bilaterally asymmetrical subcutaneous growths that overlie the dorsal aspect of the finger or toe interphalangeal joint or, less commonly, the metacarpophalangeal joint 2. Knuckle pads are usually skin-coloured, firm and painless. However, they can lead to discomfort and large knuckle pads can cause difficulty moving the fingers or toes 3."
