Severe psoriasis entering remission after treatment for latent tuberculosis with isoniazid: Report of two cases.

Psoriasis is a multifactorial systemic disease with predominantly cutaneous manifestations. The role of tuberculosis infection in the pathogenesis of psoriasis has not been consistently proven. Current guidelines recommend screening for tuberculosis infection in any patient with psoriasis when the initiation of biologic therapy is being considered.

Steroid-resistant eosinophilic fasciitis successfully treated with addition of extracorporeal photopheresis.

Eosinophilic fasciitis (EF) is an uncommon fibrosing disease of the fascia with characteristic cutaneous and hematologic manifestations. Although EF is most commonly treated with corticosteroids at the beginning, a considerable number of patients show an inadequate response and hence various therapeutic strategies have been tried, including extracorporeal photopheresis (ECP). We describe the case of a 66-year-old woman with steroid-resistant EF that improved significantly after ECP was added to her treatment regimen.
