Patho Buccal: Intra Cours 1: Intro Prendre en considération les dx dif Ex. Ulcère solitaire could also be ulcère traumatique, aphteux ou carcinome épidermoïde. Éléments à ressortir pendant l’anamnèse : P, Q, R, S, T P : palliatif – provocateur. What causes, worsens or eases pain. Q: qualité. Describe pain. R: region ou site. What region the pain touches. S: sévérité. Intensity of pain. T: temps. Chronological description of pain. A proper clinical exam must consist of: Inspection: Sound produced by a tissue or organ. Identify noises from articulations (craquement, crépitement). Palpation: Touch. Texture of tissues. Can help with DX. Olfaction: Smell. Identifies certain DX (periodontal disease, GUN, non-controlled diabetes, maligne buccal tumor). Percussion: Auscultation: LEARN MINI-ATLAS! EXAM document! You should also read “Oral and Maxillofacial Pathology” by Neville, 5th version. You should also know details of last year’s notes. He can ask us to describe a lesion. But MOST IMPORTANTLY, do a correlation between what is happening in the mouth and the pathologic report. Do this format: description, demographic, histology, differential DX, prognostic. Description of lesion example: nodule. Couleur rose pale. Sur intérieure de la muqueuse jugale. Cécile (base + large que top) ou pédiculée (top + large que base) Primary lesions: (9) Macule: plane, alteration of color (any color) Papule: slightly raised, NO liquid, variable size (< 5 mm) Plaque: slightly raised (like papule), size > 5 mm Nodule : raised surface, larger than papule, + profondeur (sub-cutanous or sub- muquous), masse tissulaire Tuméfaction: PATHOLOGICAL increase in volume (gonflement), NO palpable mass Vésicule: raised WITH LIQUID (serum, blood, plasma), caused by formation of cavités intra-épidermiques, dimension < 5 mm Bulle: raised WITH LIQUID (serum, blood, plasma), similar to vésicule but larger at its base and + deep, diameter > 5 mm Pustule: contains pus Kératose: white-colored lesion, caused by exaggerated deposition of keratin on epithelium surface Secondary lesions: (9) Érosion: superficial loss of tissue due to trauma, does NOT touch couche basale germinative, generally no scar (cicatrice) Ulcération: loss of continuity of surface epithelium, with or without scar Fissure: depression in tissue resulting in linear loss of continuity of epithelium Pseudo-membrane: reaction from secondary mucous to necrotic agent, seen often in surface of ulceration Escarre: necrosis of tissue by thermal, chemical or gangrère Squames: accumulation of cellular fragments from couche cornée, may cover surface of erosion Desquamation: loss of superficial epithelium (détachement des squames) Croûtes: déssechement of exsudat (blood, plasma, pus) on surface of lesion Cicatrice : fibrous replacement tissue Quelques données démographiques: Âge: ▪ Gingivostomatite herpétique primaire: ENFANTS > adultes ▪ Herpes buccal récurent : ADULTES > enfants Sexe : ▪ Cancer buccal et leucoplasies : FEMMES > hommes ▪ Lichen plan : HOMMES > femmes Race : ▪ Dysplasie cémento-osseuse périapicale : NOIRS > blancs ▪ Maladie Paget et lupus érythémateux : BLANCS > noirs Sites : ▪ Cancer buccal : plancher et bord latéral > palais dur ▪ Leucoplasie chevelue : latéral > ailleurs ▪ Nodule sur joue : polype fibro-épithélial ▪ Nodule sur palais : tumeur glande salivaires mineurs Prévalence : ▪ Lichen plan > lupus érythémateux ▪ Leucoedème > noevus blanc spongieux Signes vs symptômes : ▪ Signes : something you can see, objective ▪ Symptôme : something the patient describes, subjective Cours 2: Maladies osseuses
