Cytology of cutaneous lesions.

Cytology is a quick, easy, and inexpensive way to gain useful information concerning the process(es) or etiology of cutaneous lesions. Cutaneous lesions can be separated quickly into inflammatory or noninflammatory conditions and organisms and neoplastic cells can be identified, allowing for a definitive diagnosis. Although not all lesions can be diagnosed cytologically, recognition of the process(es) (for example, purulent inflammation, eosinophilic inflammation, cysts) allows for better therapeutic management and a more accurate prognosis.
