All right. Next up, we're going to
talk about atopic, contact,
and seborrheic dermatitis.
Let's jump into our case.
We have an 18-year-old English
major with a history of
"dermatitis." Presents today to
talk about an intensely
pruritic rash in the antecubital
fossae of both arms.
She also has a history of allergic rhinitis,
mild asthma, seasonal allergies --
typical atopic history. No fevers,
no chills, no dyspnea.
Social and family history, she's a non-smoker,
her mother has asthma,
her brother is allergic to "everything."
Again, sounds like a atopic
history both amongst herself and
her family members.
Review of systems is negative. And then
on skin exam, you see dry,
lichenified, erythematous plaques with
scattered papules and excoriations
in the antecubital fossae. There's a good
picture of it there on the right.
So which of the following is the
most likely diagnosis?
Right off the bat, I know we're all thinking
about atopic dermatitis,
but let's methodically go through each
one of the things on this list
to make sure that we don't forget to
look at those other ones.
