A 74-year-old man presented to our clinic with a 10-year history of an asymptomatic eruption consisting of large annular lesions on the upper part of the trunk and arms. The lesions first appeared as smaller lesions on the upper back area and progressively expanded to cover most of the back, chest, and proximal aspect of the arms. The patient had a history of type 2 diabetes mellitus and hypertension, for which he had been taking an oral hypoglycemic (gliclazide) for more than 15 years; he was also on an antihypertensive regimen (trimetazidine, perindopril, and amlodipine besylate). He had a skin phototype III and reported a tendency for burning on initial sun exposure, followed by tanning.
