Pityriasis rubra pilaris (PRP) refers to a group of erythematous, scaling dermatologic conditions that have been associated with seronegative arthritis. We report a case of polyarthritis in a young man with PRP in which magnetic resonance imaging suggested an entheseal‐based pathology for the joint disease. The arthritis, but not the skin condition, demonstrated dramatic response to anti–tumor necrosis factor immunotherapy.
