Complex Hand Polydactyly: A Case Report and Literature Review.

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatric Surgery

Background:

• Polydactyly is a common congenital anomaly characterized by the presence of supernumerary digits.
• It can manifest as an isolated finding or as part of a broader genetic syndrome.
• Most cases are sporadic and unilateral, though population-specific incidences vary.

Observation:

• This report describes a rare case of bilateral complex hand polydactyly.
• The affected individual is a 1-year-7-month-old girl of African descent.
• The patient had no family history of malformations and no other associated anomalies, suggesting an isolated, non-syndromic presentation.

Findings:

• The presented case exhibits a rare pattern of bilateral complex hand polydactyly.
• The condition was not consistent with known syndromic diseases.
• Surgical resection of the extra digits was performed.

Implications:

• This case highlights the diverse presentations of polydactyly, even in non-syndromic forms.
• Early surgical intervention can effectively improve cosmesis and function in complex polydactyly.
• Further research into the genetic and developmental underpinnings of rare polydactyly presentations is warranted.
