Seborrheic eczema

Seborrheic eczema is localized on the skin of the scalp, as well as the face, chest, interscapular region. Vesiculation and oozing are extremely rare in these patients. The presence of seborrhoids (rounded yellowish-pinkish erythematous spots covered with greasy yellowish scales) is characteristic.
Abundant layered yellowish crusts and scales appear on the scalp, the hair on the affected areas is shiny, sometimes glued together in the form of tufts ( tinea amiantacea ). Serous -purulent exudation is often observed in the folds behind the auricles . Patients complain of itching (sometimes very intense), which may precede the development of clinical manifestations. Increased sensitivity to polyamide and flannel fabrics, contact with which causes a relapse of the disease.
Currently, there is no single point of view on seborrheic eczema. Even LN Mashkilleyson (1965) emphasized that some authors identify seborrheic eczema and superficial streptoderma . However, we believe that the term “seborrheic eczema” objectively reflects the essence of the pathological process and its morphology.
As for the microbial infection, in such patients it can play the role of an antigen. There is no doubt that the violation of the state of the neuroendocrine system and the reactivity of the body is of pathogenetic importance in this Dermatosis. So, for example, infants suffer from seborrheic eczema. At the same time, it almost never occurs between infancy and puberty, but occurs, like seborrhea, more often after puberty (the role of hyperandrogenism or hypoestrogenism ).
