Area of Science:

Hand surgery
Pediatric orthopedics
Vascular anomalies

Background:

Vascular malformations are relatively common in the hand.
Previous reports have documented various locations, but not within the flexor tendon sheath.

Observation:

An 8-year-old girl presented with a capillary vascular malformation.
The malformation was exclusively located within the flexor tendon sheath.

Findings:

This case represents the first reported instance of a vascular malformation involving the vinculum of the flexor tendon sheath.
The malformation was entirely contained within the tendon sheath.

Implications:

Highlights the importance of considering unusual locations for vascular malformations in the hand.
