Which of the following best describes Lippel-Trenaunay Syndrome?

• A. A condition causing only varicose veins
• B. A collection of conditions involving dysplastic soft tissue structures
• C. A syndrome characterized by capillary malformation and hypertrophy of structures
• D. A rare disorder unrelated to mesodermal structures

Answer: (C)

Lippel-Trenaunay Syndrome is best described as a syndrome characterized by capillary malformation and hypertrophy of structures. This condition is marked by three primary features: capillary malformation, which often presents as vascular birthmarks, hypertrophy or overgrowth of one limb, leading to asymmetry, and varicose veins or venous malformation.

The identification of this syndrome is essential as it aids in recognizing the associated anomalies and helps guide appropriate management for affected individuals. Patients typically present with one limb larger than the other due to the hypertrophy, which can complicate mobility and function. The capillary malformation aspect can lead to cosmetic concerns, and the presence of varicosities can result in venous insufficiency.

Differentiating Lippel-Trenaunay Syndrome from other conditions is crucial for accurate diagnosis and treatment. While other options may have elements that are somewhat related, none encompass the full spectrum of features that define this syndrome. Thus, the description focusing on capillary malformation and hypertrophy provides a comprehensive understanding of Lippel-Trenaunay Syndrome, aligning with what is known about its clinical presentation and implications.
