Abstract

Trachyonychia is a nail alteration which may be caused by several inflammatory diseases that affect the nail matrix keratinization. The pathogenesis of trachyonychia is still unknown but its occurrence in autoimmune or immune-mediated skin conditions suggests that an immunological reaction against nail matrix keratinocyte antigens may be involved. There are no clinical criteria which permit us to distinguish spongiotic trachyonychia, the most common type, from that due to other inflammatory skin diseases, i.e. lichen planus, psoriasis, eczema, pemphigus vulgaris. Spongiotic trachyonychia occurs in association with alopecia areata or as an idiopathic condition. Since spongiosis of the nail matrix is detected not only in trachyonychia, but also in the other nail abnormalities associated with alopecia areata, we can speculate that idiopathic spongiotic trachyonychia may represent a variety of alopecia areata limited to the nails.
