|
This patient came with the sign of Berkley membrane ,which is seen in psoriasis
| Psoriasis is characterized by well-circumscribed, sharply demarcated erythematous papules and/or plaques. |
On grattage, silvery white scales come off in layers.
After their removal, a characteristic coherence is observed, as if one scratches on a wax candle (candle grease sign).
On further grattage, a thin peel like membrane, Berkley’s membrane, is seen which comes off as a whole
