Question 6

Eczema

The condition described in the extract is eczema, characterized by severe itching, dry skin, and small lesions. The patient's family history of allergic rhinitis further supports this diagnosis, as eczema is often associated with other atopic conditions.

A) Fever blisters

Fever blisters, or cold sores, are typically caused by the herpes simplex virus and present as painful, fluid-filled blisters, primarily around the lips or mouth. They do not align with the symptoms of dry skin and itching described in the extract.

B) Eczema

Eczema is a chronic inflammatory skin condition that often presents with dry, itchy skin and lesions, which matches the symptoms noted in the extract. The connection with allergic rhinitis in the patient's family history also supports this diagnosis, as eczema is part of the atopic triad, which includes asthma and allergic rhinitis.

C) Shingles

Shingles, caused by the reactivation of the varicella-zoster virus, typically presents with a painful rash that follows a dermatomal pattern and is associated with blistering. This does not fit the description of severe itching on the face with dry skin and small lesions.

D) Acne

Acne is primarily characterized by the presence of comedones, papules, and pustules, often associated with hormonal changes and not typically associated with dry skin or severe itching. The symptoms described do not correspond to those of acne.

Conclusion

Eczema is the definitive diagnosis in this case due to the presence of severe itching, dry skin, and lesions, along with the patient's family history of allergic rhinitis. Other options such as fever blisters, shingles, and acne do not align with the symptoms presented, confirming that eczema is the correct answer.
