Compared to the MED protocol, the induration method allows for clinicians to modify the dose as plaques begin to change in response to treatment. Finally, use of clobetasol spray and ointment in conjunction with the excimer laser resulted in a safer side effect profile, as well as improved clearance of lesions in the long term.30. The combined analysis of these studies showed that $64 of patients with palmoplantar pustular psoriasis experienced an improvement of at least 70% at the end of treatment. This protocol identifies the minimum dose at which the patient will blister, and then subsequent treatments are administered at doses less than the MBD. The treatment protocol used in that study involved stepwise dose increments similar to conventional phototherapy.

Guidelines of care for the management of psoriasis and psoriatic arthritis. After 5 weeks of therapy (receiving a total of nine excimer laser treatments and clobetasol spray twice daily) the patients’ hairline psoriasis was completely cleared. The mechanism of action of the excimer laser, similar to the action of UVB light, induces apoptosis in keratinocytes and T lymphocytes. 308 nm excimer laser phototherapy is efficacious in the treatment of localized psoriasis. 2015;41(11):1201–1211. In general, four main categories of cutaneous diseases can be currently treated with the 308 nm excimer laser: psoriatic lesions—which will be the focus of this review—apigmented and hypopigmented lesions, pruritic disorders, and follicular diseases. Overall, the 308 nm excimer laser is a very well tolerated treatment option for patients with psoriasis. This is often useful for patients with limited scalp involvement.35, Treatment of scalp psoriasis has been reported, but this modality presents challenges due to the difficulty of penetrating the laser through the hair. The PHAROS excimer laser is different from cosmetic lasers that are usually associated with pain during treatment and post-treatment downtime for the patient. Frentzen M, Koort HJ, Thiensiri I. Excimer lasers in dentistry: future possibilities with advanced technology. The most commonly observed side effects are erythema, blistering, hyperpigmentation, and hypopigmentation.32 These side effects are typically observed only at the sites of treatment, they do not occur in all treatments, and are often well tolerated by patients. This article has no funding source. Dermatol Surg. It must be noted however that the forehead, hairline, and retroauricular areas are not entirely covered by hair, and often treatment with the excimer laser is a viable option.36 Wong et al present a case of a 68-year-old female patient with generalized plaque psoriasis, also involving the hairline of the scalp. Int J Hyperthermia. Bonis et al were the first to study the use of the 308 nm XeCl excimer laser in the field of dermatology in 1997.

However, when considering patients with mild to moderate psoriasis, it can be an extremely useful treatment. Randomized, prospective trials are needed to establish laser therapy protocols for maintaining the plaque clearance achieved with the 308 nm excimer laser. The absorption of 308 nm wavelength induces DNA breakage, upregulation of the tumor suppressor gene p53, and subsequent reduction of proto-oncogene Bcl-2, leading to cell cycle arrest in keratinocytes and T lymphocytes.1 This breaks the positive feedback loop and halts the psoriatic disease cycle created by the activated T lymphocytes. The Lancet. 2007. The patient was subsequently discontinued from all prior treatments and started on excimer laser treatments twice weekly. Half of the scalp received excimer laser treatment, whereas the other half of the scalp served as a control. It is a complex immune-mediated disease propagated by abnormal interactions between T lymphocytes, dendritic cells, keratinocytes, neutrophils, and proinflammatory cytokines. When compared to the narrow band UVB laser, the 308 nm laser has an increased induction rate of T-cell apoptosis.1 Compared with traditional narrow band UV therapy, the excimer laser requires on average less number of treatment sessions and thus a smaller amount of cumulative UVB exposure.
