Diseases of the skin and subcutaneous tissue (dermatology)

Ectodermal dysplasia: causes, symptoms, diagnosis, treatment

Ectodermal dysplasia is a group of hereditary diseases caused by abnormal development of the ectoderm, and is combined with various changes in the epidermis and appendages of the skin.

Congenital epidermolysis bullosa (hereditary pemphigus): causes, symptoms, diagnosis, treatment

Congenital bullous epidermolysis (hereditary pemphigus) is a large group of noninflammatory skin diseases characterized by a tendency of the skin and mucous membranes to develop blisters, mainly in places of minor mechanical trauma (friction, pressure, solid food intake).

Pigmented xeroderma

Pigment xeroderma is a hereditary disease transmitted by an autosomal gene inherited from parents and relatives and has a family character.

Neurofibromatosis: causes, symptoms, diagnosis, treatment

Neurofibromatosis (Recklinghausen's disease) is a hereditary disease characterized by a malformation of ecto- and mesodermal structures, mainly skin, nervous and bone systems, with an increased risk of developing malignant tumors.

Darya disease (follicular vegetative dyskeratosis): causes, symptoms, diagnosis, treatment

Darya disease is a rare disease characterized by pathological keratinization (dyskeratosis), precipitation of horny, mostly follicular, papules on seborrheic areas.

Porokeratosis

Porokeratosis unites a group of diseases characterized by a violation of keratinization.

The syndrome of Neterton: causes, symptoms, diagnosis, treatment

EV Netterton (1958) described the combination of ichthyosis - ichthyosiform congenital erythroderma (lamellar ichthyosis) with hair lesion in the form of nodular trichorexis in combination with atopy.

Keratoderma: causes, symptoms, diagnosis, treatment

Keratoderma - a group of dermatoses characterized by a violation of the processes of keratinization, - excessive horn formation mainly of the palms and soles.

Ichthyosis

Ichthyosis is a group of hereditary skin diseases characterized by a disturbance of keratinization. Causes and pathogenesis are not fully understood. Many forms of ichthyosis are based on mutations or disturbances in the expression of genes encoding various forms of keratin. With lamellar ichthyosis deficiency of transglutaminase keratinocytes and proliferative hyperkeratosis are noted.

Subcorneal pustulosis: causes, symptoms, diagnosis, treatment

The disease was first described in 1956 by English dermatologists Sneddon and Wilkinson. Until recently, in the literature, the question was discussed whether the disease is an independent nosological form of dermatosis or under its mask there are pustular psoriasis, herpetiform impetigo of Gebra, pustular form of Dühring's dermatitis and a number of other skin diseases.
