Darier's disease (DD) is a rare, genetic skin disorder. It is an autosomal dominant disorder, that is, if one parent has DD, there is a 50% chance than a child will inherit DD. It was first reported by French dermatologist Ferdinand-Jean Darier in 1889.
Darier's sign is a change observed after stroking lesions on the skin of a person with systemic mastocytosis or urticaria pigmentosa. [1] In general, the skin becomes swollen, itchy and red. This is a result of compression of mast cells, which are hyperactive in these diseases. These mast cells release inflammatory granules which contain ...
It was first described by Darier in 1916. [ 3 ] [ 4 ] [ 5 ] Many different terms have been used to classify these types of lesions and it is still controversial on what exactly defines EAC. Some of the types include annular erythema (deep and superficial), erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier erythema ...

Doctors can confirm the presence of mast cells by rubbing the baby's skin. If hives appear, it most likely signifies the presence of urticaria pigmentosa. [citation needed]
Whether acrokeratosis verruciformis and Darier disease are related or distinct entities has been controversial, like Darier's disease, it is associated with defects in the ATP2A2 gene. [4] however the specific mutations found in the ATP2A2 gene in acrokeratosis verruciformis have never been found in Darier's disease. [5]
Polydactylous longitudinal erythronychia has been most commonly associated with Darier's disease [10] and lichen planus [11] but has also occasionally been associated with acantholytic epidermolysis bullosa, [12] no association, [13] graft-versus-host disease, [14] [15] hemiplegia, [16] and systemic amyloidosis.

The other diseases were a follicular keratosis (Darier-White syndrome), dermatofibrosarcoma (Darier-Ferrand disease), erythema annularis, subcutaneous sarcoidosis (Darier-Roussy sarcoid), and a sign, Darier's sign observed in mastocytosis. From 1909 to 1922, Darier was head of the clinical department at the Hôpital Saint-Louis. [5]
