Question 1

Which skin condition is commonly associated with overactive sebaceous glands?

Accepted Answer

Acne

Answer

Acne vulgaris is a common inflammatory skin condition primarily caused by the overproduction of sebum by sebaceous glands, often triggered by hormonal changes. This excess sebum, combined with dead skin cells, clogs hair follicles, leading to the formation of blackheads, whiteheads, pimples, and cysts.

Question 2

What is a hallmark symptom of eczema (atopic dermatitis)?

Accepted Answer

Itchy, inflamed skin

Answer

Eczema, particularly atopic dermatitis, is characterized by intensely itchy, red, and inflamed skin. Patients often experience dry, scaly patches that can sometimes blister or ooze, leading to significant discomfort and a strong urge to scratch.

Question 3

Which condition results from an autoimmune attack on skin pigmentation cells?

Accepted Answer

Vitiligo

Answer

Vitiligo is an autoimmune condition where the body's immune system mistakenly attacks and destroys melanocytes, the cells responsible for producing skin pigment (melanin). This results in characteristic smooth, white patches of skin that lack pigmentation.

Question 4

What type of lesion is associated with psoriasis?

Accepted Answer

Scaly plaques

Answer

Psoriasis is a chronic autoimmune condition characterized by the rapid overproduction of skin cells, leading to thick, red patches covered with silvery scales, known as plaques. These plaques are typically well-demarcated and can appear on various parts of the body.

Question 5

Which condition is characterized by facial redness and visible blood vessels?

Accepted Answer

Rosacea

Answer

Rosacea is a chronic inflammatory skin condition primarily affecting the face, characterized by persistent facial redness, visible blood vessels (telangiectasias), and often papules and pustules. It typically affects the central face, including the nose, cheeks, forehead, and chin.
