What is your diagnosis???

A 69-year-old man presented to the dermatology clinic with a 2-month history of a pruritic rash. The rash first appeared on his right wrist and within 2 weeks had spread to his arms, legs, and trunk. He had completed treatment for chronic hepatitis C virus (HCV) infection with a 12-week course of elbasvir and grazoprevir 3 months before the onset of the purple papular rash. Some lesions showed a fine reticulate pattern of dots and lines (Wickham’s striae). What is the diagnosis? a) Drug eruption b) Reactivation of endogenous latent varicella-zoster virus c) Discoid lupus erythematosus d) Lichen planus e) Pemphigus source: nejm.org
