Sebopsoriasis is a skin condition that bridges the gap between seborrheic dermatitis and psoriasis, exhibiting characteristics of both. According to the provided reference, sebopsoriasis represents an overlap between two separate conditions: seborrhoeic dermatitis and psoriasis, where features of each condition are present simultaneously. It's essentially a transitional state between these two distinct skin disorders.
In simpler terms:
- Seborrheic dermatitis primarily affects areas rich in oil glands (sebum), like the scalp, face, and chest, causing redness, flaking, and greasy scales.
- Psoriasis is an autoimmune condition that results in raised, scaly plaques on various parts of the body.
Sebopsoriasis combines these features.
Key Features of Sebopsoriasis
The characteristics of sebopsoriasis are diverse because it sits between two distinct conditions.
- Overlap: It's not purely seborrheic dermatitis nor purely psoriasis.
- Location: Common areas affected include the scalp, face (especially around the eyebrows and nose), ears, and chest.
- Appearance: Lesions can present with both the greasy scales typical of seborrheic dermatitis and the well-defined, raised plaques associated with psoriasis.
- Scale Color: Scales might be yellowish (more like seborrheic dermatitis) or silvery-white (more like psoriasis).
Understanding the Distinction

| Scale Type | Greasy, yellowish | Dry, silvery-white | Mix of greasy/dry; yellowish or silvery-white |
| Inflammation | Mild | Moderate to severe | Varies, usually mild to moderate |
