I would hope to look at the different clinical presentations of various conditions and look at
their histopathology eg various clinical presentations of lupus erythematosus.

Another approach to differential diagnoses is to look at certain clinical presentations such as
scarring alopecia, red facial nodules, indurated skin, oral and genital ulcerations etc and know
what the common clinical differential is going to be. You put yourself in the mind set of the referring
Clinician. We will have a Module or Modules dedicated to this approach AND we will continually
alude to it during the clinical aspects of the course. See DermPath Correlation

We will also expand on the Differential Diagnoses Mnemonics. Learn them! They really will help
put you in your referring clinicians' shoes. You will know what they are thinking even if they have
not expressed it in the referral note!

Part 2:
Lymphomas This specific area of Dermatopathology more than probably any other, requires
specific clinical information because conditions with vastly different prognoses can look very similar
histologically.

Also the term Pseudolymphoma can be refined if you have a knowledge of the clinical situation. eg
a pseudolymphomatous infiltrate secondary to tatoo, vaccine or persistent herpes virus infection. A
similar picture can be seen with Mollusca and in post scabetic nodules. Lymphocytoma cutis is a
term that describes a red or purplish facial nodule secondary to an insect bite reaction or to
Borrelia in Europe from a tic bite.Reactive lymphoid hyperplasia is another term that is used to
describe this lymphocytic infiltrate when the cause is known.
