Non scrappable white papules intermixed with areas of erythema and erosion most likely falls under:

 # Non scrappable white papules intermixed with areas of erythema and erosion most likely falls under: 

A. Candidiasis 

B. Erythroleukoplakia 

C. Leukoplakia 

D. Erythroplakia 

The correct answer is B. Erythroleukoplakia.

The term 'non homogeneous' is ascribed to lesions with two different features, usually having both red and white areas, but also to all those without redness but containing verruciform exophytic elements. Due to the combined appearance of white and red areas, the nonhomogeneous oral leukoplakia has also been called erythroleukoplakia and speckled leucoplakia. The clinical manifestation of the white component may vary from large white verrucous areas to small nodular structures. If the surface texture is homogeneous but contains verrucous, papillary (nodular), or exophytic components, the leukoplakia is also regarded as nonhomogeneous.

The glycoprotein antigen chiefly detected in pemphigoids is:

 # The glycoprotein antigen chiefly detected in pemphigoids is: 

A. BP 180 and 230 

B. DSG 2 and 3 

C. BP 130 and 280 

D. DSG 1 and 4 

The correct answer is A. BP 180 and 230.

Bullous Pemphigoid is an autoimmune disease caused by the binding of autoantibodies to specific antigens found in the lamina lucida region of the basement membrane on the hemidesmosomes of epithelial basal cells. These antigens are glycoproteins referred to as bullous pemphigoid antigens, BP 180 and BP 230. Binding of antibody to antigen activates both leukocytes and complement, causing localized damage to the basement membrane, resulting in vesicle formation in the subepithelial region.

Blisters containing clear fluid, less than 1cm in diameter is:

 # Blisters containing clear fluid, less than 1cm in diameter is: 

A. Vesicle 

B. Bulla 

C. Pustule 

D. Nodule 

The correct answer is A. Vesicle.

Vesicles: These are small blisters containing clear fluid that are less than 1 cm in diameter.

Bullae: These are elevated blisters containing clear fluid that are greater than 1 cm in diameter.

Pustules: These are blisters containing purulent material and appear yellow.

Nodules: These lesions are present within the deep mucosa. The lesions may also protrude above the mucosa forming a characteristic dome‐shaped structure. A good example of an oral mucosal nodule is the irritation fibroma.

Dressler syndrome is a complication of:

 # Dressler syndrome is a complication of:

A. Hypertension

B. Pericarditis

C. Mitral stenosis

D. Myocardial infarction

The correct answer is D. Myocardial infarction.

Dressler syndrome is a secondary form of pericarditis that occurs in the setting of injury to the heart or the pericardium (the outer lining of the heart). It consists of fever, pleuritic pain, pericarditis and/or a pericardial effusion.

Dressler syndrome is also known as postmyocardial infarction syndrome and the term is sometimes used to refer to post-pericardiotomy pericarditis.

It was first characterized by William Dressler at Maimonides Medical Center in 1956.
