The lungs are the most commonly affected organ in sarcoidosis, with pulmonary involvement occurring in more than 90% of patients diagnosed with the condition.

Question 2

Which of the following complications arising from Sj&#246;gren's syndrome is most significant?&#10;A) General malaise and fatigue&#10;B) Development of non-Hodgkin's lymphoma&#10;C) Dry eyes (xerophthalmia)&#10;D) Parotid gland enlargement&#10;E) Development of cervical caries

Accepted Answer

The development of non-Hodgkin's lymphoma is considered the most significant complication of Sjögren's syndrome due to its potential to be life-threatening. Sjögren's syndrome increases the risk of lymphoma, a type of cancer, which is a more severe outcome than the other complications listed.

Question 3

Stevens-Johnson syndrome is a severe form of which of the following?&#10;A) Herpes simplex&#10;B) Lupus erythematosus&#10;C) Herpes zoster&#10;D) Erosive lichen planus&#10;E) Erythema multiforme

Accepted Answer

Stevens-Johnson syndrome is considered a severe form of erythema multiforme, which is a condition that affects the skin and mucous membranes and can be triggered by infections, medications, or other factors.

Question 4

Raynaud's phenomenon is associated with which of the following?&#10;A) Erythema multiforme&#10;B) Hashimoto's thyroiditis&#10;C) Diabetes mellitus&#10;D) Rheumatoid arthritis&#10;E) Systemic sclerosis (scleroderma)

Accepted Answer

Raynaud's phenomenon is commonly associated with systemic sclerosis (scleroderma), where it is often one of the first symptoms.

Question 5

All of the following are oral effects of systemic sclerosis (scleroderma)except which one?&#10;A) Development of microstomia&#10;B) Loss of attached gingiva&#10;C) Generalized gingival recession&#10;D) Vesiculobullous lesions&#10;E) Widened periodontal ligament space

Accepted Answer

Vesiculobullous lesions are not typically associated with systemic sclerosis (scleroderma). Systemic sclerosis is characterized by hardening and tightening of the skin and connective tissues, which can lead to microstomia, loss of attached gingiva, generalized gingival recession, and widened periodontal ligament space, but not vesiculobullous lesions.

Question 6

Nikolsky's sign is a characteristic feature of which of the following?&#10;A) Lupus erythematosus&#10;B) Herpes simplex&#10;C) Pemphigus&#10;D) Herpes zoster&#10;E) Eczema

Accepted Answer

Nikolsky's sign is a clinical feature indicative of skin blistering disorders, most notably seen in pemphigus. It is elicited by applying lateral pressure to the skin, resulting in the top layers of the skin shearing off. This sign is not characteristic of lupus erythematosus, herpes simplex, herpes zoster, or eczema.

Question 7

Characteristic skin lesions of erythema multiforme most closely resemble which of the following?&#10;A) Aphthous ulcers&#10;B) Leukoplakia&#10;C) White striations&#10;D) Target or bull's-eye lesions&#10;E) Caf&#233;-au-lait spots

Accepted Answer

Erythema multiforme is characterized by target or bull's-eye lesions on the skin, which are distinctive for this condition.

Question 8

Which of the following oral diseases do lesions of lupus erythematosus most closely mimic?&#10;A) Cicatricial pemphigoid&#10;B) Pemphigus&#10;C) Sarcoidosis&#10;D) Systemic sclerosis (scleroderma)&#10;E) Erosive lichen planus

Accepted Answer

Lesions of lupus erythematosus can closely mimic erosive lichen planus in their appearance and distribution within the oral cavity, making it a condition that needs to be considered in the differential diagnosis. Both conditions can present with erythematous, erosive, or ulcerative lesions that may be painful or asymptomatic.

Question 9

Oral radiographs of a patient with scleroderma would show which of the following?&#10;A) Abnormal trabecular bone formation&#10;B) Thickened periodontal ligament&#10;C) Absence of lamina dura&#10;D) Horizontal bone loss&#10;E) Vertical bone loss

Accepted Answer

In scleroderma, oral radiographs often show a thickened periodontal ligament due to the excessive collagen deposition characteristic of the disease.

Question 10

Xerostomia is related to which of the following?&#10;A) Peutz-Jeghers syndrome&#10;B) Antibiotic therapy&#10;C) Sj&#246;gren's syndrome&#10;D) Benign tumors of the parotid gland&#10;E) Multiple mucoceles

Accepted Answer

Xerostomia, or dry mouth, is commonly associated with Sjögren's syndrome, an autoimmune disorder that affects the salivary glands, leading to decreased saliva production.

Question 11
