Abstract
Clear cell acanthoma (CCA) is a rare, benign epidermal lesion of clear glycogen-containing keratinocytes. The exact etiology is unknown. Although CCA usually appear as solitary lesions, cases of multiple CCAs have also been described. The rare eruptive CCA variant describes cases with more than 30 lesions.

Current therapeutic evidence for the management of multiple CCAs is limited. CO2 laser remains the most widely used laser in clinical practice. However, literature describing its effectiveness on CCA is sparse, and previous reports have described its use for a maximum of three lesions. To our knowledge, this is the first report of successful CO2 laser treatment of the multiple eruptive CCA variant with an excellent cosmetic outcome.

Our case adds to the evidence that CO2 laser is an effective treatment for this condition. Particularly in those patients with refractory or multiple eruptive CCAs, or for those who may not tolerate repeated courses of cryotherapy, or who are concerned about scarring and cosmetic outcome.
