Introduction: Infantile digital fibromatosis (FDI) is a rare, recurrent, benign tumor that occurs in the fingers and toes at birth or in the first months of life. We report a new case.
Case report: A 2 1/2-year-old girl had light-pink, non-painful, hard, solid tumor formations, sitting on the dorsal surface of the fifth metatarsal bilaterally and the 2nd phalanx of the 5th left finger, resulting in joint deformity and then functional discomfort. X-rays of the front and the profile of the fingers showed a chondroma of P2 of the 5th finger, without anomaly on the X-ray of the knees. On the ultrasound of the soft parts: the presence of soft masses very hypoechogene avascular compared to the 5th ray measuring 2.81cm on the right and 1.21cm on the left. The diagnosis of infantile digital fibromatosis was retained. Surgical treatment was undertaken.
Conclusion: The FDI is a rare and often easy diagnostic entity. Its recognition is important to consider adequate treatment knowing that this lesion can regress spontaneously and that post-surgical recurrence are frequent.
