Pigmented lesions of the oral cavity: review, differential diagnosis, and case presentations

J Can Dent Assoc. 2004 Nov;70(10):682-3.


Pigmented lesions are commonly found in the mouth. Such lesions represent a variety of clinical entities, ranging from physiologic changes to manifestations of systemic illnesses and malignant neoplasms. Evaluation of a patient presenting with a pigmented lesion should include a full medical and dental history, extraoral and intraoral examinations and, in some cases, biopsy and laboratory investigations. In this paper, an algorithm is proposed for the assessment of pigmented lesions of the oral cavity, and 3 patients with such lesions are described.
