RESUMEN
Darier disease is an uncommon hereditary skin disorder characterized by the presence of hyperkeratotic papules and plaques affecting seborrheic areas. The uniqueness of this case lies in the exceptionally late-onset pattern of Darier disease, involving an 82-year-old female patient, and its correlation with COVID-19 infection. The patient had a history of a scaly and itchy rash limited to her arms, initially misdiagnosed as dermatitis, which persisted and worsened over three months. The manifestation of classical features of Darier disease coincided with her recent contraction of COVID-19. This instance emphasizes the varying manifestations of Darier disease that appear very late in life, which could result from new mutations or partial penetrance. Additionally, this case points out the potential worsening of Darier disease when combined with a COVID-19 infection. It highlights the need to be aware of atypical clinical progressions and the potential for increased severity of skin disorders during COVID-19. More studies are essential to grasp the relationship between COVID-19 and inherited skin conditions, aiming to improve patient treatment and care approaches.
