Cutaneous granuloma annulare in an adult patient with macrophage activation syndrome

Abstract

Abstract Macrophage activation syndrome (MAS) is a rare but life‐threatening disorder that is associated with multiple organ involvement. Here, we described cutaneous granuloma annulare in MAS. This novel histological finding is a reminder to explore the underlying mechanisms of skin involvement in MAS, which may reveal its pathogenesis.
