QUESTION 1
What is a steatoma?
Answer: Sebaceous cyst of subcutaneous tumor filled with sebum.
Rationale: A steatoma is a benign subcutaneous tumor characterized by its cyst-like structure filled with keratinous material
and sebum, arising from a blocked sebaceous gland. This diagnostic criterion distinguishes it from other epidermal cysts or
lipomas.
QUESTION 2
The cause of acne vulgaris is
Answer: Chronic inflammation of hair follicles and associated sebaceous glands, 1. hormone associated
increase in sebum production and excess keratin production block follicles, forming comedones.
Rationale: Acne vulgaris arises from pilosebaceous unit inflammation, triggered by hormonal increases in sebum and
keratin, leading to follicular obstruction and comedone formation. This pathophysiology explains the characteristic lesions of
acne.
QUESTION 3
What is a subjective symptom found during a skin analysis?
Answer: Inflamed skin.
Rationale: Inflamed skin is a subjective symptom reported by the patient, indicating an internal response to irritation or
injury, whereas other findings like dryness or scaling are objective observations. The key concept tested is the distinction

scutula.
Rationale: Tinea favus, also known as tinea favus, is a specific type of fungal infection characterized by the formation of
dry, sulfur-yellow, cup-shaped crusts called scutula, typically on the scalp. This clinical presentation is the hallmark
diagnostic feature of this dermatophytosis.

Rationale: Alopecia is a medical term denoting abnormal hair loss from the scalp or body. This condition can stem from
various factors including genetics, hormonal changes, medical conditions, or medications.

Answer: Large blister containing watery fluid.
Rationale: A bulla is a circumscribed, elevated lesion measuring greater than 1 cm in diameter, characterized by a
collection of serous fluid within the epidermis or beneath it. This key dermatological concept distinguishes bullae from
smaller vesicles based on size.
QUESTION 7
What lesions should barbers be aware of?
Answer: Primary and secondary.
Rationale: Barbers must recognize primary and secondary syphilis lesions to prevent transmission, as these stages are
