Papuloerythroderma of Ofuji

Research output: Contribution to journalArticlepeer-review


Papuloerythroderma of Ofuji (PEO) is a rare skin condition first described in 1984 and characterized by diffuse erythroderma composed of papules coalescing into plaques with sparing of skin folds, known as the deck-chair sign. The disease is almost exclusively seen in the elderly and affects men more frequently than women. Common laboratory findings include peripheral and tissue eosinophilia, elevated levels of immunoglobulin E, and lymphopenia. The diagnosis entails exclusion of potentially causative pathologies, including drug intake, atopy, malignancy, and infection. These factors have frequently been found in association with PEO, but their role in the etiopathogenesis of the disease is poorly understood. A dysregulated immune system, with particular involvement of T-helper (Th)2 and Th22 cells, seems to be important in the development of PEO. Controversy exists as to whether PEO exists as an independent entity or as a clinical pattern of a variety of distinct conditions. Treatment necessitates first addressing any coexisting circumstances that may have a causal relationship with PEO. In idiopathic cases, topical and oral corticosteroids, ultraviolet light therapies, and immunosuppressive/immunomodulating therapies have been used with variable results. Future studies are needed to further understand the disease process and to establish guidelines for diagnostic workup and treatment.
