Allergic dermatitis due to topical antibiotics.

Area of Science:

• Dermatology
• Allergology
• Pharmacology

Background:

• Allergic contact dermatitis is an immune response to topical agents.
• Antibiotic ointments are commonly used for skin infections.
• Misdiagnosis can delay appropriate treatment and prolong symptoms.

Purpose of the Study:

• To report a case of allergic dermatitis caused by prolonged antibiotic ointment application.
• To emphasize the differential diagnosis between infection and allergic reaction.
• To highlight the importance of a thorough medication history.

Main Methods:

• Clinical case presentation.
• Review of patient history and symptoms.
• Diagnostic assessment for dermatitis and infection.

Main Results:

• The patient developed allergic dermatitis due to chronic antibiotic ointment use.
• The condition was initially misdiagnosed as a localized finger infection.
• Discontinuation of the offending ointment led to symptom resolution.

Conclusions:

• Allergic contact dermatitis should be considered in cases of persistent or worsening skin lesions, even when infection is suspected.
• A detailed history of topical medication use is crucial for accurate diagnosis.
• Avoiding the causative agent is key to managing antibiotic ointment-induced dermatitis.
