**Question:** An 8 month old child presented with itchy, exudative lesions on the face, palms and soles. The siblings also have similar complaints. The treatment of choice is such a patient is –

A. Hydrocortisone cream
B. Chlorpheniramine maleate
C. Methotrexate
D. Penicillin

**Correct Answer:**

**Core Concept:**

The clinical scenario described involves a child with a skin condition characterized by itchy, exudative lesions on the face, palms, and soles. The affected siblings suggest a familial or genetic predisposition to the condition, which is commonly seen in autoinflammatory diseases.

**Why the Correct Answer is Right:**

The correct answer, B. Chlorpheniramine maleate, is an antihistamine often used to treat allergic conditions, including those causing pruritus (itchiness) and exudative lesions. Chlorpheniramine maleate blocks histamine receptors, reducing histamine-induced inflammation, pruritus, and edema. In this case, it is appropriate treatment due to the child's symptoms and the involvement of siblings.

**Why Each Wrong Option is Incorrect:**

A. Hydrocortisone cream (A) is a topical corticosteroid used to reduce inflammation and suppress immune response. While it is effective for many skin conditions, the child's symptoms (pruritus and exudative lesions) suggest an autoimmune or autoinflammatory disorder, not a steroid-responsive skin condition.

C. Methotrexate (C) is an immunosuppressive agent, often used in rheumatoid arthritis treatment. However, methotrexate is not indicated for skin conditions and can have severe side effects in pediatric patients.

D. Penicillin (D) is an antibiotic used to treat bacterial infections. The family history of affected siblings suggests an autoinflammatory disease, not a bacterial infection.

**Clinical Pearl:**

Autoinflammatory disorders, such as Familial Mediterranean Fever (FMF), are genetic diseases characterized by recurrent episodes of fever, inflammation, and skin lesions (like those described). These conditions are often misdiagnosed as infectious or allergic disorders, highlighting the importance of considering familial factors when evaluating pediatric patients with skin symptoms.

**Explanation:**

The correct answer, Chlorpheniramine maleate, is a first-line treatment for allergic and inflammatory skin disorders in children. In this case, it is the appropriate choice due to the child's symptoms (pruritus and exudative lesions) pointing to an autoimmune or autoinflammatory disorder. Chlorpheniramine maleate helps alleviate pruritus and reduce inflammation, making it suitable for treating the described symptoms.

**Why Other Options are Incorrect:**

A) Hydrocortisone is an immunosuppressive agent commonly used in rheumatological conditions, not appropriate for treating inflammatory skin disorders.

C) Methotrexate is an immunosuppressive drug used to treat rheumatological conditions, not suitable for
