Abstract
- Unilateral linear capillaritis (ULC) is a rare variant of pigmented purpuric dermatosis (PPD). ULC is clinically characterized by unilateral linear macules on the lower extremities, which fade spontaneously. We present three patients with linearly distributed purpuric macules on only one side of the lower extremities. Skin biopsy showed histopathological features of PPDs. We diagnosed ULC based on these clinicopathological findings. For all patients, the skin lesions began to fade spontaneously within several months to a few years after onset. ULC has been reported rarely, with only about 20 cases worldwide and no cases described in the Korean literature.
