Epidemiology
A fibroblastic lesion of infants and young children that affects the fingers or toes. Because some lesions regress, operating up front can be worse than watchful waiting if the finger keeps good function.
Basic features
It produces firm nodules that can deform the digit, limit movement, or make wearing shoes and bearing weight difficult.
Usual treatment
Observation is reasonable if function is not compromised; surgery is reserved for pain, progressive deformity, or limitation.
Outcomes and prognosis
It can regress spontaneously, but can also recur after surgery, so management aims to avoid functional damage.
