Exam 3: Immunity and Immunologic Oral Lesions

Which form of Langerhans cell disease resembles lymphoma, affects children younger than 3 years, and has a rapidly fatal course?

A prodromal period begins:

The onset of this condition is explosive. It is characterized by skin and mucosal lesions. The skin lesions are referred to as target, iris, or bull's eye lesions. The mucosal lesions affect the buccal mucosa, lips, and tongue and appear as superficial ulcerations. The lip lesions are ulcerated, encrusted, and bloody. On the basis of this description, you suspect:

The eye damage that occurs in Sjögren syndrome is called:

This patient presents with an intraepithelial bulla from breakdown of the cellular adhesion between epithelial cells. The bulla ruptured, resulting in a painful ulcer with itching. The correct diagnosis for this progressive autoimmune disease is:

The breakdown of cellular adhesion between epithelial cells is called:

Pemphigus vulgaris differs histologically from cicatricial pemphigoid in that pemphigus vulgaris involves:

Which one of the following is an example of type I hypersensitivity?

A patient presents with a diffuse swelling of the upper lip caused by permeability of deeper blood vessels. The skin covering the swelling appears normal and not accompanied by itching. This is characteristic of what pathological condition?

In the mildest form of this autoimmune disease, oral lesions appear as erythematous plaques or erosions. White striae radiating from the center of the lesion are also commonly present. These oral lesions are indicative of what autoimmune disease?

This patient has Sjögren syndrome and severe xerostomia. Which clinical feature most appropriately describes the changes on the tongue in this patient?

The most common oral manifestation of Sjögren syndrome is:

The major divisions of the immune response are the cell-mediated and humoral responses. Both of these responses originate from what type of cell?

The classic triad of symptoms seen in 25% of patients with Hand-Schüller-Christian disease includes all of the following except:

Which one of the following routes of drug administration can cause the most significant hypersensitivity reaction?
