What's your diagnosis?

An otherwise healthy 22-year-old woman presented with a painful eruption with burning and pruritus that had been slowly worsening as it spread over the last 4 weeks. The rash first appeared on the lower chest and inframammary folds and spread to the upper chest, neck, back, arms, and lower face. Physical examination revealed multiple illdefined, erythematous papules, patches, and plaques on the chest, back, neck, and upper abdomen. Individual lesions coalesced into plaques that displayed a reticular configuration. There were no lesions in the axillae. The patient had been following a low-carbohydrate diet for 4 months. A punch biopsy was performed.⁠ ⁠
