RESUMO
Epidermal nevi (EN) are cutaneous hamartomas present at birth, usually occurs in the trunk, the face, or the limbs, appearing as a patch of overgrowing skin. They may be small and localized, but they may interest extensive areas of the body. A 20 years old man came to our attention for an EN interesting all the face. The treatment protocol consisted of a session of CO2 laser in order to vaporize thicker areas, followed by a session of dye laser on the area to prevent scarring. This treatment was performed under local anesthesia and sedation in three surgical sessions spaced 3 months from each other. Two sessions of dye laser spaced apart 6 months were performed during follow-up to further improve the esthetic outcome. The patient was followed for 2 years with no recurrence. Although surgery is still considered the gold standard in EN management, it is not always feasible. This novel combination technique can obtain optimal cosmetic results with no relapse within the period of follow up. Although further trials on a more significant number of patients are required, the combination of CO2 and dye laser promises to become a valid therapeutic alternative when treating giant EN of the face.

COVID Vaccine Arm (CVA) is an adverse drug reaction from mRNA vaccine for SARS-CoV-2. CVA is characterized by erythema and edema on the vaccination site (usually deltoid area) that appears from 5 to 10 days after vaccination and is sometimes associated with itching or pain. The exact etiology of CVA is still unclear, but delayed hypersensitivity against an excipient seems to play an essential role in the pathogenesis of the disease. This work performs a systematic literature review on CVA using three different databases containing articles published until 10 November 2021. The literature review includes eight papers reporting single cases or case series of CVA. Moreover, it also addresses, other cutaneous reactions following COVID 19 vaccinations as well as possible differential diagnosis. CVA migrans-like erythema is characterized by a ring-shaped rash in the injection area, which appears some days after the injection and disappears in about 10 days. This reaction may appear more rapidly in subsequent doses.
