Gibbs et al reported an algorithm for diagnosing a patient with livedo reticularis (LR). The authors are from the University of Pittsburgh.
Patient selection: presence of livedo reticularis
Patient group: infant vs older patient
Infant with LR |
Diagnosis |
---|---|
resolves with warming |
livedo marmorata |
does not resolve with warming |
livedo marmorata telangectasia congenita |
where:
• The algorithm in implementation is modified to include LR secondary to a systemic disorder.
Evaluation of the older adult:
(1) resolution quickly and completely with warming
(2) underlying systemic disease
(3) continuously present
Resolves with Warming |
Underlying Systemic Disease |
Continuously Present |
Diagnosis in Older Patient |
---|---|---|---|
Yes |
NA |
NA |
cutis marmorato or physiologic LR |
No |
Yes |
NA |
LR secondary to systemic disorder |
No |
No |
Yes |
idiopathic LR |
No |
No |
No |
primary LR |
Purpose: To evaluate a patient with livedo reticularis (LR) using the algorithm of Gibbs et al.
