The clinical presentation of many disease processes can be very similar, which can complicate management. Since treatment and prognosis are based on the diagnosis, the diagnostic process is critical in optimal patient management. This brief lecture provides some definitions and illustrations to enable the clinician to better describe the appearances of lesions and communicate these features to colleagues. Macule: Focal area of color change that is Papule: Solid, raised lesion that is less than 5 mm in not elevated or depressed in relation to its surroundings. diameter. 1  Oral pathology 1 MAJD & SHATHA Lecture 2 Nodule: Solid, raised lesion that is greater than 5 mm in diameter. Papillary: Describing a tumor or growth exhibiting numerous surface projections. Sessile: Describing a tumor or growth Verrucous: Describing a tumor or growth whose base is the widest part of the lesion. exhibiting a rough, warty surface. Pedunculated: Describing a tumor or growth whose base is Vesicle: Superficial blister, 5 mm or less in diameter, narrower than the widest part of the lesion. usually filled with clear fluid. 2  Oral pathology 1 MAJD & SHATHA Lecture 2 Bulla : Large blister, greater than 5 mm in diameter. Erosion: Superficial lesion, often arising secondary to rupture of a vesicle or bulla, that ischaracterized by partial or total loss of the surface epithelium. Pustule: Blister filled with purulent exudate. Fissure: Narrow, slit-like ulceration or groove. Ulcer : Lesion characterized by loss of the surface Plaque: Lesion that is slightly elevated and epithelium and frequently some the underlying connective is flat on its surface. tissue. It often appears depressed or excavated. 3  Oral pathology 1 MAJD & SHATHA Lecture 2 Petechia: Round, pinpoint area of hemorrhage. Cyst: Pathologic epithelium-lined cavity, often filled with liquid or semi-solid contents. Ecchymosis:Non- elevated area of hemorrhage, larger than a Unilocular: Describing a radiolucent lesion having a petechia single compartment Telangiectasia: Vascular lesion caused by dilatation of a small, superficial blood vessel. Multiocular: Describing a radiolucent lesion having several or many compartments. 4
