Macrodystrophia lipomatosa with syndactyly

Area of Science:

• Medical imaging
• Orthopedics
• Genetics

Background:

• Macrodystrophia lipomatosa (MDL) is a rare congenital condition causing localized gigantism.
• It involves hypertrophy of mesenchymal tissues, notably adipose tissue, in affected digits.
• Syndactyly, or fused digits, is an uncommon but recognized association with MDL.

Observation:

• This report details a unique case of MDL affecting the hand.
• The case presented with the rare co-occurrence of syndactyly.
• Clinical presentation included significant digital overgrowth and fusion.

Findings:

• Radiographic and Magnetic Resonance Imaging (MRI) were crucial in diagnosis.
• Imaging revealed characteristic patterns of adipose tissue overgrowth and osseous hypertrophy.
• Specific findings helped distinguish this case from other forms of localized gigantism.

Implications:

• Accurate diagnosis of MDL with syndactyly is essential for appropriate management.
• Understanding imaging findings aids in differentiating MDL from other gigantism etiologies.
• This case contributes to the literature on rare congenital hand anomalies.
