Purpose: Hexadactyly is a congenital physical anomaly, potentially affecting the hand or the food. Aim of this study is to report two case reports of hexadactyly involving the four limbs, with a literature review focused on this pathology.

Methods: This article describes the treatment proposed in two patients with hexadactyly, from the birth to one year follow-up. A literature search was performed to compare the different treatment choices.

Result: The treatments described for hexadactyly can be conservative or surgical, with good results in both cases. The main aspect to consider is the functionality of the extra-digits.

Conclusion: Hexadactyly of the four limbs is a relevant clinical condition under many aspects and requires a careful multidisciplinary evaluation.
