Diagnose this case by Hesham Alshaikh, MD, and Alison Bailey, MD

A 50-year-old female presented to the dermatology clinic with a 3-week history of two growing “bumps” on the midchest. She has no similar lesions elsewhere and no prior treatments attempted. No personal or family history of autoimmune disorders. A review of symptoms was negative, specifically for vulvar pruritus and dyspareunia. However, she did note that her gynecologist recommended starting hydrocortisone for an asymptomatic rash in her groin. Physical examination revealed two circinate atrophic ivory-colored papules with an erythematous rim and follicular plugging. Punch biopsy for H&E confirmed the suspected diagnosis.
