Various scientists separate Psoriasis by different Types
E. Chritophers and W. Sterry (1993)
Scientists E. Chritophers and W. Sterry separate the following Types of Psoriasis:
|
the Non-pustular forms:
|
the Pustular forms:
|
- Common Psoriasis:
- with the early beginning (type I)
- with the late beginning (type II)
- Psoriatic Erythroderma;
|
- Palmoplantar Pustular Psoriasis (Barber's type);
- Pustular Psoriasis, which flows similar to the type of centrifugal ring-shaped erythema;
- Generalized Pustular Psoriasis.

B.N. Mordovtsev (1995)
B.N. Mordovtsev separates the following Types of Psoriasis:
- Plaque (vulgar) Psoriasis;
- Psoriatic erythroderma;
- Arthropathic Psoriasis;
- Pustular Psoriasis;
- Generalized Psoriasis;
- Limited Palmoplantar Psoriasis (Barber's type);
- Psoriasiform pustular dermatosis:
- Chronic acrodermatitis (Allopo);
- Pustular bacterid (Andrews);
- Generalized psoriasiform pustulosis;
- Impetigo herpetiformis;
- Psoriasis, which flows similarly to the type of centrifugal ring-shaped erythema.
D. Matthews and co-authors (1996)
D. Matthews and co-authors separate the following Types of Psoriasis:
- Type 1 (with an early beginning at an age of up to 40 years), which is associated with the HLA antigens and the family inheritance of Psoriasis with predisposing genes, located on chromosomes 4q, 6p, 16q, 17q and 20p;
- Type 2 (with a late beginning at an age older than 40 years), with a weak bond to the HLA antigens, the absence of family history of Psoriasis and a larger predisposition to the damage of the joints and nails.
R.D.R. Camp, PhD. (1999)
A Researcher from The University of Leicester (England) R.D.R. Camp, PhD in the Rook/Wilkinson/Ebling textbook separates the following Types of Psoriasis:
- By Types
(drop-like Psoriasis, rupioid Psoriasis, unstable Psoriasis, pustular Psoriasis, erythrodermic Psoriasis)
- By Location
(Psoriasis of the scalp, inverted Psoriasis, Psoriasis of palms and soles, Psoriasis of the nails),
- Atypical Types
(linear Psoriasis, seborrheic Psoriasis, mucous membranes Psoriasis, eye Psoriasis).
Braun-Falco, O. and the co-authors (2000)
German dermatologists Braun-Falco, O. and the co-authors separate latent Psoriasis (with the genetic innate predisposition, special features of metabolism, structural and functional changes in the skin established, as a rule, in the families of the people with Psoriasis), and manifestation Psoriasis, which they divide into the following types:
a) based on the size and nature of the lesions:
- Drop-like Psoriasis;
- Follicular Psoriasis;
- Coin-like Psoriasis;
- Geographic Psoriasis;
- Psoriatic erythroderma.
b) based on the configuration of the lesions:
- Ring-shaped Psoriasis; Spiral-shaped Psoriasis;
- Serpiginous Psoriasis (serpiginous - creeping, advancing - means that such a disease leaves scar tissue below while continuing to affect the skin above);
c) based on the localization of the psoriatic lesions:
- Psoriasis of the scalp;
- Psoriasis of the skin folds;
- Perianal (internal and external areas around the anus) Psoriasis;
- Penile Psoriasis;
- Psoriasis of the palms and soles;
- Psoriasis of the nails;
- Psoriasis of the mucous membranes;
- Psoriasis with the damage of the internal organs.
N.B. Kungurov and co-authors (2002)
N.B. Kungurov and co-authors separate 4 Types of Psoriasis, based on the type of the initiating action and taking genetics into account:
- Stress-induced Psoriasis
(emotional or physical stress);
- Predominantly autoimmune Psoriasis
(Psoriasis with the progressive activity);
- Infection-caused form
(bacteria, viruses);
- Spontaneous or sporadic Psoriasis
(without the genetic predisposition and in the absence of the initiating factor).
