to carefully examine these areas

Answer 4

2-true……it will exacerbate the skin disease, if severe
try methotrexate which is effective against both skin and joint disease
3-like the genitals and the natal clefts ……so always
examine these areas especially in join disease with out any apparent skin
involvement ( so you will think of another diagnosis like rheumatoid factor
negative rheumatoid arthritis ) , the patient might be shy from telling you
that these areas are involved .
4-false in children and some may develop chronic
plaque type upon reaching adulthood
