White Lesions Flashcards
white plaque on the alveolar ridge, painless, may be rough, poorly demarcated
Often in the area of previously extracted mandibular third molar
Alveolar ridge keratosis (ARK)
Very common lesion
secondary to pressure, friction, or suction trauma from facial surface of teeth
bilateral white line at the occlusal level of teeth
found ONLY in dentulous areas
Linea Alba
Secondary to chronic nibbling of cheeks, labial mucosa or lateral borders of the tongue
Females > males
Thick, shredded white areas with occasional erythema and ulceration
Most commonly found bilaterally on buccal mucosa
Morsicatio
Very common lesion
Black adults > White adults
Diffuse, milky gray opalescent mucosa
Disappears when stretched
May also appear on the floor of the mouth and palatopharyngeal tissues
Leukoedema
Accumulation of keratin on the filiform papillae of the tongue dorsum
Associated with: smoking antibiotic therapy poor oral hygiene radiation
Hairy Tongue
Located at sites of tobacco contact with oral mucosa
Young adult men and those over 65 yrs
Gray-white plaque, fissured/rippled surface
resolves in 1-2 weeks following cessation
Tobacco Pouch Keratosis
Chronic, progressive oral mucosal scarring
High-risk precancerous condition
Associated with BETEL QUID chewing
Buccal mucosa, retromolar pad, soft palate, tongue
treat with intralesional corticosteroids and surgical splitting of bands
sometimes pale color on the palate
Oral Submucous Fibrosis
Secondary to heat, not tobacco exposure
Not considered a premalignant lesion
Men over 45 years old with long history of tobacco use
Gray to white lesion with punctate red papules representing inflamed salivary gland ducts
Nicotine Stomatitis
Pre-malignant alteration of lower-kip vermillion
Secondary to UV exposure
Males > Females
Blurring of vermilion-skin interface**
6% squamous cell carcinoma
Actinic Cheilosis
Secondary to acute or chronic trauma
Variability in healing time
Often exhibit a white, rolled border on clinical examination
Traumatic Ulceration
Autosomal dominant inheritance
Symmetric, thickened, white diffuse plaques
Bilaterally on buccal mucosa
White Sponge Nevus
Extensive, irregular white plaques
Involves multiple mucosal sites
Persistent growth, exophytic and verrucous
May lead to dysplasia, squamous cell carcinoma
Female predilection
Proliferative Verrucous Leukoplakia (PVL)
Most often older men
Caused by extrinsic/intrinsic factors
Can present as: Exophytic Endophytic Leukoplakic Erythroplakic
Squamous Cell Carcinoma
No granular cell layer
Nuclei are retained in keratin layer
Parakeratin (hyperkeratosis)
Granular cell layer
Nuclei lost in keratin layer
Orthokeratin (hyperkeratosis)
