Treatment of facial lesions of multicentric reticulohistiocytosis by carbon dioxide laser

The carbon dioxide (CO 2 ) laser is a versatile tool that has applications in ablative lasing and caters to the needs of routine dermatological practice as well as the esthetic, cosmetic, and rejuvenation segments. We report a case of multicentric reticulohistiocytosis with cosmetically disfiguring confluent papules over the scalp, forehead, nasolabial folds, chin, and retroauricular region. We used CO 2 laser in superpulse mode for ablating the lesions in three sittings. The lesions regressed completely and no recurrence was observed over a regular follow-up of 8 months.
