Papuloerythroderma of Ofuji is a rare skin condition first described by Japanese dermatologists Ofuji et al. in 1984. It is characterized by the presence of red, flat, and slightly elevated papules that tend to coalesce into large plaques. The disease is more common in elderly individuals and has been associated with various internal malignancies.

Clinical Features

These papules often coalesce to form large plaques that cover a significant portion of the body. The plaques are typically symmetrical and have a characteristic "deck-chair" distribution, sparing the skin folds. Other symptoms may include pruritus, fever, and malaise.
