The B lymphocytes play a central role. a. both true b. both false c. first true; second false d. first false; second true - Answer b (lichen planus; T lymphocytes) - intraepithelial clefting above the basal cell layer - basal cells have a characteristic "tombstone" appearance - acantholysis is present a. pemphigus b. cicatricial pemphigoid c. bullous pemphigoid d. epidermolysis bullosa acquisita e. lichen planus - Answer a - subepithelial clefting with epithelial separation from the underlying lamina propria, leaving an intact basal layer (2 answers) a. pemphigus b. cicatricial pemphigoid c. bullous pemphigoid d. epidermolysis bullosa acquisita e. lichen planus - Answer b, c - similar to bullous and cicatricial pemphigoid a. pemphigus b. cicatricial pemphigoid c. bullous pemphigoid d. epidermolysis bullosa acquisita e. lichen planus - Answer d - hyperkeratosis, hydropic degeneration of the basal layer, and sawtooth rete pegs - lamina propria exhibits dense, bandlike infiltrate, primarily of T lymphocytes - colloid bodies present a. pemphigus b. cicatricial pemphigoid c. bullous pemphigoid d. epidermolysis bullosa acquisita e. lichen planus - Answer e - similar to erosive lichen planus - hyperkeratosis, acanthosis, basal cell layer liquefaction, subepithelial clefting and lymphohistiocytic chronic infiltrate in a bandlike configuration a. chronic ulcerative stomatitis b. linear IgA disease c. dermatitis herpetiformis d. systemic lupus erythematosus e. chronic cutaneous erythematosus f. subacute lupus erythematosus - Answer a - similar to erosive lichen planus - linear deposits of IgA at the basement membrane zone a. chronic ulcerative stomatitis b. linear IgA disease c. dermatitis herpetiformis d. systemic lupus erythematosus e. chronic cutaneous erythematosus f. subacute lupus erythematosus - Answer b - hyperkeratosis, basal cell degeneration, epithelial atrophy, and perivascular inflammation (2 answers) a. chronic ulcerative stomatitis b. linear IgA disease c. dermatitis herpetiformis d. systemic lupus erythematosus e. chronic cutaneous erythematosus f. subacute lupus erythematosus - Answer d, e - less inflammatory cell infiltrate than systemic and chronic cutaneous forms but with similar microscopic features a. chronic ulcerative stomatitis b. linear IgA disease c. dermatitis herpetiformis d. systemic lupus erythematosus e. chronic cutaneous erythematosus f. subacute lupus erythematosus - Answer f There are several clinical forms of oral lichen planus. The most common are atrophic and bullous. a. both statements are true b. both statement are false c. first is true; second is false d. first is false; second is true - Answer c (reticular and erosive) - collection of neutrophils, eosinophils, and fibrin in the connective tissue papillae a. chronic ulcerative stomatitis b. linear IgA disease c. dermatitis herpetiformis d. systemic lupus erythematosus e. chronic cutaneous erythematosus f. subacute lupus erythematosus - Answer c The typical erosive subtype of lichen planus is often associated with pain. The reticular subtype is asymptomatic and bilateral. a. both statements are true b. both statements are false c. first is true; second is false d. first is false; second is true - Answer a which of the following is a false statement concerning desquamative gingivitis? a. clinical term not a diagnosis b. gingival response associated with a single condition c. 75% of cases have a dermatologic genesis d. cicatricial pemphigoid and lichen planus account for over 95% of dermatologic cases - Answer b (associated with a variety of conditions) the incidence of oral lichen planus is approximately 0.1-4%. One fourth of patients with oral lichen planus presents cutaneous lesions. a. both statements are true b. both statements are false c. first statement is true; second statement is false d. first statement is false; second statement is true - Answer c (one-third) (T/F) in oral lichen planus, oral lesions predominantly occur in the posterior regions of the buccal mucosa - Answer true - hyperkeratosis or parakeratosis - hydropic degeneration of the basal layer - dense bandlike T-lymphocyte infiltrate in the lamina propria - "saw tooth" configuration of rete pegs - subepithelial vesicles - Answer lichen planus In lichen planus, the keratotic lesions have no tx but require follow up every 6 to 12 months. The symptomatic lesions require a ointment containing a high potency steroid. a. both statements are true b. both statements are false c. first statement is true; second statement is false d. first statement is false; second statement is true - Answer a accumulation of fluid either within or below the epidermis and mucous membrane
