Case of acne conglobata successfully treated by CO2 laser combined with topical tretinoin therapy

Abstract

Acne conglobata is an uncommon disorder characterized by the presence of nodulocystic lesions. Conservative therapy with oral and topical antibiotics is of limited efficacy in many cases, and surgical excision is often needed for removal of the cystic lesions. Treatment is particularly difficult in cases with lesions located in aesthetically sensitive areas, such as the face. We successfully treated a case of acne conglobata by CO(2) laser ablation to remove the top of the sinuses and their tracts. In addition, topical tretinoin therapy was also initiated simultaneously to prevent the appearance of new acne lesions. Based on the results, we propose that the use of CO(2) laser for opening the cysts, combined with topical tretinoin therapy to prevent the appearance of new lesions, is a powerful treatment option for acne conglobata.
