[Fibronectin in the skin of patients with allergic dermatitis].

In the skin of healthy subjects linear deposits were found of fibronectin at the dermoepidermal junction and in the walls of blood vessels, and reticular deposits in the papillary and reticular layers of the skin. In the epidermis of 12 out of 51 patients with allergic contact dermatitis fibronectin deposits were found in relation to Langerhans cells and keratinocytes. This was not observed in the epidermis in healthy subjects. The authors suggest that fibronectin on the surface of Langerhans cells and keratinocytes may play a role in antigen presentation.

[Ultrastructural image of the Langerhans cells in the skin of patients with allergic contact dermatitis].

The alterations in the ultrastructural feature of Langerhans cells in patients with allergic contact eczema were characterized by significant increase in number of Birbeck granules accompanied by the increase in volume of smooth- and rough-surfaced endoplasmic reticulum. These changes may be regarded as a morphological expression of the increase of the synthetic and secretory activity of the Langerhans cells. In the epidermis the Langerhans cells associated with immediately adjacent precursor cells (the so called indeterminate cells), lymphoid cells and keratinocytes form the morphologically visible and probably functional units.

[Incidence of contact allergy in patients with eczema nummulare].

In patients with eczema nummulare patch tests with a panel of 18 allergens were done with positive result in 9 (18%) cases. In 6 cases multivalent allergy was found. Most frequently positive tests were obtained with potassium dichromate. The tests showed participation of contact allergy in the development of changes in a part of patients with eczema nummulare.
