However, immunocompromised patients such as solid organ transplant recipients are at higher risk of developing severe forms of the disease. Herein, we describe the case of a 43 years-old female kidney transplant recipient that manifested severe skin ulcers alongside nodular lung opacities and pleural effusion attributed directly to the Monkeypox virus. Notwithstanding the initiation of early treatment with tecovirimat, a satisfactory response was not achieved until a reduction in immunosuppression to everolimus monotherapy, coupled with the transition to cidofovir for antiviral treatment. In conclusion, mpox has the potential to produce a severe form of systemic infection in individuals who have undergone solid organ transplantation, demanding a meticulous approach involving sequential antiviral treatment and modifications to immunosuppressive regimens in order to achieve complete healing.
