Allergic dermatoses associated with chronic opisthorchiasis during antihelminthic therapy.

We studied skin biopsy specimens from patients with allergic dermatoses associated with opisthorchiasis. Structural changes in the epidermis and derma were presented by degenerative and destructive changes in epitheliocytes with a pronounced membranolytic component, hemodynamic disturbances in the derma, disorganization of the connective tissue, and progressive fibrosis. Combination therapy including antihelmintic drug produced a positive effect, which was associated with induction of regenerative processes in basal epidermal cells, stabilization of the basal membrane, and normalization of the dermoepidermal junction. Our findings indicate that opisthorchiasis plays an important role in the pathogenesis of allergic dermatoses.
