Common Lesions Flashcards
Term for “mole” - benign melanocytic lesion
Nevus
Term for “freckles” - brown pigmentation that develops following sun exposure
Ephelides
Benign melanocytic lesion - macular (flat), increase in number in Caucasians with age, no change with UV exposure
Lentigo
Benign skin lesion with a “stuck on” appearance - looks like “dropped on candlewax”
Seborrheic keratosis
Precursor lesion for cutaneous squamous cell carcinoma. “Sandpaper” texture.
Actinic keratosis
Prominent vessels, often an indication of sun damage
Telangectatic capillaries
Usually over 40 yo often seen on forehead, central unbilication
Sebaceous hyperplasia
Most common cancer in humans - seen in “mask area” with rolled borders, umbilicated center, and telangiectasia
Basal cell carcinoma
Ectopic sebaceous glands - most common on the buccal mucosa
Fordyce granules
Associated with the loss of vertical dimension. Candida, some may have co-infection with candida and staph
Angular cheilitis
Variant of seborrheic keratosis that occurs in many black persons
Dermatosis papulosa nigra
Most common site for recurrent HSV-1
Herpes labialis (vermilion border and/or adjacent skin of lips)
Focal increase in melanin; also can occur as reactive melanosis in response to local trauma
Melanotic macule
Focal deposition of mucous caused by damage of associated minor salivary gland duct
Mucocele
Intracellular edema
Leukoedema
Found along occlusal plane
Linea alba
Cheek/tongue/lip biting/chewing
Morsicatio buccarum, linguarum, labiorum
Benign collection of dense fibrous connective tissue
Fibroma
Immunologically mediated process. Often as “striae” or lacy clinical presentation. Does not wipe off
Lichen planus
Comprised of dense, vital, lamellar bone
Tori
Found under sub-optimally fitting RPD or full denture, may also reflect nearly constant wear
Inflammatory papillary hyperplasia
Inflamed minor salivary glands of the palate with hyperkeratosis around the orifices (often in pipe smokers)
Nicotine stomatitis
Overgrowth of chromogenic bacteria and filiform papillae
Black hairy tongue
Multiple grooves in tongue, often associated with geographic tongue
Fissured tongue
Tongue sensitive to spicy or acidic food when lesions are present
Geographic tongue
Part of Waldeyer’s ring - Vertical lines at posterior lateral tongue often see lymphoid tissue in that area
Foliate papilla
Intraoral opening of sinus track
Parulis
Inflammation - most common in mandibular third molars
Pericoronitis
Punched out interental papillae that do not regenerate
Necrotizing ulcerative gingivitis (NUG)
Associated most often with poorly fitting dentures
Inflammatory fibrous hyperplasia
Most often in older patients - lower lip frequent site. If thrombosed, will NOT blanch with diascopy
Varix
Loss of continuity of an epithelial or epidermal covered surface
Ulcer
Immune mediated - found on freely movable oral mucosa - “canker sore”
Aphthous ulcer
Associated with NON-oncogenic HPV - color depends on amount of keratin on the surface
Squamous papilloma
White patch with crisply defined margins that does not rub off and cannot be diagnosed clinically or microscopically as anything else
Leukoplakia
Seen in root of tooth, need biopsy to confirm and assess vitality of adjacent teeth
Periapical cyst
Develops due to fluid entrapment between crown of impacted tooth and reduced enamel epithelium
Dentigerous cyst
Collection of fluid below maxillary sinus - maxillary sinus lining will be superior to the fluid collection - may get referred pain to maxillary teeth with altitudes (ex: flying)
Antal pseudocyst
Radiopaque lesion at base of tooth - look for tooth or teeth with deep caries in area
Condensing osteitis
Bony protuberances that arise from cortical plate
Exostoses
Seen in a radiograph - dense, vital bone - no identifiable etiology - blends with surrounding trabeculae
Idiopathic osteosclerosis
2 other names for idiopathic osteosclerosis
Enostosis or dense bone island
