Abstract

Background: Perforating skin dermatoses include elastosis perforans serpiginosa (EPS), reactive perforating collagenosis, Kyrle's disease and perforating folliculitis. In addition to these four diseases, an acquired form of perforating dermatosis associated with diabetes mellitus and/or chronic renal failure has been reported for which the term acquired perforating dermatosis (APD) was proposed. The molecular mechanism of transepidermal elimination of dermal components in perforating skin dermatoses remains unclear. We recently demonstrated that the 67-kDa elastin receptor can be detected in the epidermis eliminating altered elastic fibres in EPS, suggesting that the elastin-keratinocyte interaction may play a role in transepidermal elimination in EPS. Objectives: To determine whether the 67-kDa elastin receptor is involved in other perforating diseases. Methods: Paraffin-embedded skin specimens from new cases of EPS (n = 2), APD (n = 15) and perforating granuloma annulare (PGA; n = 2) were studied immunohistochemically using a specific antibody to the 67-kDa elastin receptor. In one case of EPS, two different sites from a single lesion, a central atrophic area and a peripheral keratotic area, were studied. Results: Expression of the elastin receptor was detected in the epidermis surrounding the elastic materials in both cases of EPS. The elastin receptor was not detected in the central inactive area, whereas it was expressed strongly in the peripheral keratotic active area. The elastin receptor was also detected in three of 15 cases of APD in which a few elastic fibres were found in the eliminated dermal materials. In one case of APD, the elastin receptor was not detected in spite of the presence of a few elastic fibres in the eliminated materials. The elastin receptor was not detected in either case of PGA. Conclusions: Expression of the elastin receptor in EPS was seen in both cases studied and was dependent on the stage of the lesion. Expression of the elastin receptor in APD appeared to be related to the amount of elastic fibres in the eliminated materials. Thus, expression of the elastin receptor in perforating skin disorders may depend on the stage of the lesion and/or the content of elastic fibres in the dermal materials being eliminated.
