Most dermatoses present with skin lesions with more or less distinct characteristics. Macroscopically, these original lesions are know as the "primary lesion," and identification of such lesions is "...the most important aspect of dermatologic examination."1 However, these lesions may continue to develop or be modified by regression or trauma, producing "secondary lesions."1 Additionally, on the microscopic level, these lesions can also be characterized by a distinct set of vocabulary.2
