A 33-year-old female presents to your clinic complaining of a localized rash on her hands. She denies new hand soap, lotions, and detergents. However, she says that yesterday she tried using a new cleaning product to clean her shower. On physical exam, you notice a 5 cm localized erythematous patch with the formation of vesicles. Which of the following is the most likely diagnosis?

A. Irritant contact dermatitis
B. Allergic contact dermatitis
C. Dyshidrotic dermatitis
D. Nummular dermatitis
E. Seborrheic dermatitis

Answer and topic summary

The answer is A. Irritant contact dermatitis

Irritant contact dermatitis (ICD) is the most common type of contact dermatitis. ICD is an inflammatory dermatological disorder due to a chemical or physical agent coming into contact with the skin. Common irritants include detergents, surfactants, acids, oxidizing agents (like bleach or benzoyl peroxide), alkaloids, solvents, metal tools, fiberglass, dust, and oil. On physical exam, you may note localized erythema, edema, vesicles, bullae, and oozing. Diagnosis is usually clinical. Management includes avoiding the irritant, emollients, and topical steroids.
