'''Spot [[diagnoses]]''' are (microscopic) diagnoses one can make on the spot.  They are ideal for bell-ringer type exams.
 
There is a separate article for [[gross spot diagnoses]].
 
If you are looking for questions for review/practice, take a look at the ''[[quizzes]]'' page for quick ones, and ''[[cases]]'' page for longer ones.

An exam favourite spot diagnosis (granular cell tumour).

Spot diagnoses are (microscopic) diagnoses one can make on the spot. They are ideal for bell-ringer type exams.

There is a separate article for gross spot diagnoses.

If you are looking for questions for review/practice, take a look at the quizzes page for quick ones, and cases page for longer ones.
