Dear Editor,
Methotrexate (MTX) has been successfully employed as an anti-inflammatory agent in the treatment of a variety of dermatologic conditions, such as psoriasis. Recently, many reports described adverse skin manifestations during MTX therapy. The majority of these are reported on the trunk, back, buttocks, and proximal area of extremities with non-palpable erythematous-purpuric rashes, flaccid bullae, crusted, or hemorrhagic erosions or ulceration.[1],[2] On the other hand, in the current literature there are several adverse reactions reported after covid vaccination, such as diffuse erythema, urticarial reactions, pityriasis rosea, and herpes zoster.[3],[4] The mechanism according to which the vaccine can cause this type of reaction has been widely explained in the literature, and most skin reactions are caused either by delayed hypersensitivity response to vaccination or by T-cell-mediated skin reaction due to molecular mimicry with a viral epitope.[5]
We report the case of 60 years old woman referred to us for palmoplantar psoriasis resistant to topical therapy. At the first visit, she was prescribed systemic acitretin 25 mg/day, but after 6 weeks there was no improvement, so we decided to switch to MTX 10 mg/week, administrated through subcutaneous injection. Three months later, the patient showed a marked improvement in the palmar-plantar manifestations of psoriasis, but the problem was to manage the therapy and the concomitant SARS-CoV-2 vaccine. For those with the well-controlled disease, international guidelines indicated to interrupt MTX therapy for 1 week before and after each dose of messenger ribonucleic acid (mRNA) vaccine. This recommendation, rather than the 2 weeks interruption, was based on practical considerations about the complexity of suspending MTX for 2 weeks around each of the two vaccine doses that are spaced 3–4 weeks apart, and the potential for flare associated with longer MTX interruption.[1] Thereafter, we indicated to suspend MTX 1 week before undergoing COVID-19 vaccination with Pfizer and 1 week after. Three days after vaccination, the patient returned to our facility with diffuse erythema over the entire body surface, edema of the right periocular area, and dysepithelialization with exoserosis of the back of the feet [Figure 1], and the diagnosis of adverse drug reaction was made. Thereafter, the patient was treated with corticosteroids (40 mg/die) and antihistamines (10 mg/1 ml) intramuscularly for about 3 days, followed by topical and oral corticosteroid therapy (25 mg/die) with complete remission in 1 month. Following allergologyst indication, and in prevision of the second vaccine, the basophil activation test was performed, but no reactivity emerged. | Figure 1: Erythema over the entire body surface, edema of the right periocular area, and dysepithelialization with exoserosis of the back of the foot in a psoriatic patient treated with MTX after SARS-CoV-2 vaccine

Complete blood count, inflammatory indices, and biochemical laboratory parameters were also evaluated, which were found to be in the normal range.
We believe that our case is important to highlight the possible concomitant role of the two drugs in the development of the reaction, although before the vaccination, the skin was almost cleared. We hypothesize that MTX could have cross-reacted with the vaccine, but this finding certainly needs to be further investigated with other studies. Our patient did not agree to take the second dose of the vaccine and refuse to restart MTX therapy. Probably MTX interruption for at least 2 weeks before and after the vaccination would have been safer or at least would have preserved the MTX as an important therapeutic option to manage our patient.
