Psoriasis
What it means
Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. The patches usually appear on the elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of the body. A problem with the immune system causes psoriasis: in a process called cell turnover, skin cells that grow deep in the skin rise to the surface, which normally takes a month but in psoriasis happens in just days. Psoriasis is not contagious, can last a long time, even a lifetime, and its symptoms come and go. Some people who have psoriasis also get a form of arthritis called psoriatic arthritis. In Spanish the word is also psoriasis.
Psoriasis in Spanish
- Spanish term
- Psoriasis
- Gender and article
- feminine: la psoriasis
- Pronunciation
- soh-RYAH-sees
Psoriasis is spelled the same in English and in Spanish. In Spanish it is feminine: la psoriasis, and MedlinePlus en español writes la psoriasis no es contagiosa. The matching adjective appears in artritis psoriásica, the Spanish for psoriatic arthritis. The alternative names listed in the MedlinePlus en español encyclopedia article are psoriasis en placa, psoriasis vulgar, psoriasis guttata and psoriasis pustular.
The encyclopedia says there are five main types and names them eritrodérmica, guttata, inversa, placa and pustular. For the skin changes, MedlinePlus en español uses escamas plateadas (silvery scales), parches (patches) and placas (plaques), and cuero cabelludo for the scalp. Cell turnover is recambio celular, and light therapy is fototerapia. Where the English encyclopedia says something may "trigger an attack of psoriasis," the Spanish article says desencadenar un ataque de psoriasis.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
