Abstract
Psoriasis is a chronic and multisystemic inflammatory disease, several factors can trigger it or aggravate it, including certain drugs including hydroxychloroquine. This drug, widely prescribed for COVID 19 infection, can trigger a flare-up of psoriasis, particularly the pustular form. Furthermore, patients with coronavirus 2019 infection, have increased plasma concentrations of inflammation-related cytokines which are also implicated in the etiopathogenesis of psoriasis, this may suggest that COVID-19 may be a new entity which exacerbates psoriasis. We report the observation of a patient who presented with psoriasis exacerbated by taking hydroxychloroquine following infection with covid 19.
