Case presentation

A 56-year-old man presents with a two-year history of pink plaques in his axillae. The plaques are slightly uncomfortable but not painful or pruritic. He has stopped using deodorants because they cause stinging, but the eruption has not improved. He has a history of chronic plaque psoriasis, type 2 diabetes and obesity.
