Phototherapies for the management of a large painful facial cutaneous lesion from human monkeypox infection.

Background: The management of patients with Monkeypox (MPX) infection is generally symptomatic as there has been no approved antiviral drug so far. Despite being generally a self-limited disease, some complications may be encountered such as severe pain and the formation of permanent skin scarring.

Aim: To present a case report in which a combination of antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) was used for a large facial cutaneous lesion in an MPX patient.

Case Report: A 20-year-old Caucasian man presenting with a large, painful, grayish, rubbery, well-circumscribed, deep-seated, and umbilicated ulcer on his face was treated with four daily sessions of PBMT and two sessions of aPDT every other day. Within a day, the patient's pain complaint was no longer present and a crust central area was visible. On the 4th day of laser treatment, the wound almost completely disappeared, leaving a small reddish area free of inflammation or infection signs and without unaesthetic skin scarring.

Conclusion: Given the lack of specific strategies for the management of severe MPX-related skin lesions, the current case report suggests that the concomitant use of PMBT and aPDT seems to be a promising therapeutic approach. The most appropriate laser parameters, however, should be further investigated in future studies in order to establish an effective and reliable clinical protocol.
