Background  Angioma serpiginosum is a rare, acquired vascular lesion simulating purpura, and should be differentiated from purpuric dermatoses such as Henoch-Schönlein purpura.

Observations  We report 2 cases of angioma serpiginosum examined using epiluminescence microscopy. Characteristic findings of angiomas ("red lagoons") were observed entirely or focally in these 2 cases, but not in 4 cases of Henoch-Schönlein purpura and a case of senile purpura.

Conclusion  Epiluminescence microscopy is beneficial in distinguishing angioma serpiginosum from purpuric dermatoses.
