Abstract
The carbon dioxide (CO2) 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 CO2 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.
