Intra-lesional steroid for the management of symptomatic Infantile Digital Fibromatosis.

BACKGROUND: Infantile 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 deformity

METHODS: We 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).

RESULTS: Corticosteroid 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.

CONCLUSIONS: This 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.
