Angioma serpiginosum - A report of 2 cases identified using epiluminescence microscopy

Background: Angioma serpiginosum is a rare, acquired vascular lesion simulating purpura, and should be differentiated from purpuric dermatoses such as Henoch-schonlein purpura. Observations: We report 2 cases of angioma serpiginosum examined using epiluminescence microscopy. Characteristic findings of angiomas ("red lagoons") were ob-served entirely or focally in these 2 cases, but not in 4 cases of Henoch-Schonlein purpura and a case of senile purpura. Conclusion: Epiluminescence microscopy is beneficial in distinguishing angioma serpiginosum from purpuric dermatoses.
