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.
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.

[5] He married Martha Anna Ellis in 1862; they had three sons. [5] His son Charles J. White took over his medical practice in 1914, [1] and became Edivard Wigylesicorth Professor of Dermatology at Harvard and chair of the Harvard dermatology department. His grandson, James Clarke White, was also a professor at Harvard Medical School. [6]
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 (deep ...
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]
[6] Although classically associated with psoriasis, subsequent research has found Auspitz's sign to be of very little diagnostic value for the disease. This is because several other diseases display the sign (including Darier's disease and actinic keratosis). Additionally, only a minority of psoriasis scales show it when removed (<18%). [7]
Health authorities around the world are still grappling with lessons learned at the start of the Covid-19 pandemic and trying to determine the best way to prevent a new one.. Many researchers have ...
Clinical signs of acrokeratosis include verrucous plaques and flat-topped, polygonal papules. [6] The lesions range in hue from brown to skin tone, and their friction might cause vesicles. [ 4 ] [ 7 ] The backs of the hands and feet's proximal and distal interphalangeal joints are typically where the lesions are seen. [ 8 ]
