Background: VEXAS syndrome, also known as Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic syndrome, is a newly identified genetic condition characterized by a combination of autoinflammatory symptoms and myeloid dysplasia. The initial description was documented in 2020, and since then, there has been an increasing number of cases and series reported globally. Case presentation : In this report, we present a case of VEXAS syndrome in an 88-year-old male patient. The patient has a p.Met41Val mutation in the UBA1 gene, with notable skin, joint, and lung involvement. As far as we know, this is the first documentation of VEXAS syndrome in Morocco and Africa. This condition may exhibit characteristics of recurrent fever, neutrophilic dermatitis, arthritis, and chondritis, along with cytopenias and myelodysplastic syndrome. The p.Met41Val mutation is known to be associated with severe clinical presentation and poor prognosis, with less chondritis involvement and more undifferentiated inflammatory syndrome, as seen in the described case. Conclusions: Vexas syndrome represents a prototype for a new classification of diseases, although it is still insufficiently identified in many underdeveloped countries, especially in Africa, it should be considered in elderly males with unexplained fever associated with systemic manifestations and worsening hematologic abnormalities.
