A 62-year-old female presents with erythema around the nasolabial folds and fine dandruff. What is the most likely diagnosis?

1. Rosacea

2. Tinea capitis

3. Photosensitivity reaction

4. Seborrheic Dermatitis

The correct answer is: Seborrheic Dermatitis

In this scenario, the presence of erythema around the nasolabial folds, along with fine dandruff, strongly indicates seborrheic dermatitis. This condition is characterized by red, oily, scaly patches often found on areas rich in sebaceous (oil) glands, such as the face, scalp, and behind the ears. The fine dandruff observed corresponds with the scale seen in seborrheic dermatitis, which typically appears as flakes that can often be mistaken for dry skin. Seborrheic dermatitis is common in adults and is often exacerbated by stress, changes in weather, or hormonal fluctuations. The location of the erythema around the nasolabial folds further aligns with classic presentations of this condition, as seborrheic dermatitis commonly affects these areas. Other conditions listed in the options do not fit the clinical presentation as closely as seborrheic dermatitis does. Rosacea tends to feature more persistent redness and may include visible blood vessels, but the fine dandruff is not a characteristic symptom. Tinea capitis usually involves more significant hair loss and is a fungal infection affecting the scalp, and photosensitivity reactions typically result from sun exposure, often involving more widespread rashes, rather than being restricted to the nasolabial
