Background:
Infantile digital fibroma (IDF) is a rare benign fibrous tumor of childhood that frequently recurs despite local excision. Conservative, nonsurgical management may result in regression and/or joint deformity.
Objective:
To describe the histologic features of IDF and discuss a case excised using Mohs micrographic surgery (MMS).
Methods:
Case report and review of the clinical, histologic, and ultrastructural features.
Results:
Characteristic inclusion bodies of actin were identified with hematoxylin and eosin, Masson's trichrome, and rapid actin immunostain. The tumor was debulked and the majority was removed after one stage of MMS, except where the deep margin approached the joint space. The defect healed by secondary intention. At 2 years the patient had no recurrence or functional joint deformity.
Conclusion:
MMS is a surgical treatment option for IDF.
