Papulosis fibroelastolítica del cuello. ¿Es la elastólisis de la dermis papilar un hallazgo histopatológico característico?

Abstract

Abstract—Two patients, a 69-year-old and a 70-year-old women, presented multiple symmetrical, confluent, whiteyellowish papules on the lateral and dorsal aspects of the neck. The lesions were symptomless and had appeared several years before consultation. Histopathological features disclosed a reduced amount or a complete loss of elastic fibers in the papillary dermis in both involved and non-involved perilesional skin and a non-constant thickening of collagen fibers in the papillary and reticular dermis in involved skin.Morphological similarities and a possible relationship between reports of white fibrous papulosis of the neck (WFPN) and pseudoxanthoma-elaticum-like papillary dermal elastolysis (PEL-PDE) are discussed. Both entities share similar clinical features and under both concepts identical lesions have been reported. The observation of papillary dermal elastolysis in both non-involved and involved skin seems to suggest that this finding should not be considered a diagnostic characteristic feature.Probably both entities should be considered as a unified disorder (fibroelastolytic papulosis of the neck). These entities probably correspond, as has been previously proposed, to morphological variants that reflect cutaneous intrinsic aging (fibroelastolytic patterns of intrinsic skin aging).
