Intra-lesional steriod for the management of symptomatic Infantile Digital Fibromatosis

SummaryBackgroundInfantile Digital Fibromatosis (IDF) is a benign, often asymptomatic nodular proliferation of fibrous tissue occurring almost exclusively on the extremities. Conventional treatment has included radical surgery but this is associated with a high level of recurrence. Whilst some authors suggest a strictly conservative approach, this is unacceptable when lesions become symptomatic from pain, contracture formation or functional deformityMethodsWe present a retrospective analysis of 12 symptomatic lesions of which 7 were treated with a novel technique of intra-lesional steroid.From 2004–2009, a total of ten patients received treatment for symptomatic IDFs. Patients were followed-up for an average of 5 years 9 months (range 8–131 months).ResultsCorticosteroid was well tolerated with no significant complications and was associated with lower morbidity that compared with surgery. There was no significance difference between rate of recurrence (1/7 vs. 5/10) for those treated with corticosteroid than compared to those patients who underwent surgery (p = 0.3) but the study is underpowered.ConclusionsThis is the first ever study to look at the role of intra-lesional steroid in the management of IDF. Whilst the majority of asymptomatic Infantile Digital Fibromatoses can be safely observed until natural resolution, intra-lesional corticosteroid is a safe and well-tolerated alternative to surgery for all symptomatic digital fibromatoses of infancy. We suggest it replaces surgery as first-line treatment but look forward to a large multicentre trial to allow comparison.
