White fibrous papulosis of the chest and back: A case report

Abstract

White fibrous papulosis (WFP) is a rare, benign dermatologic condition within the spectrum of fibroelastolytic papulosis of the neck (FEPN). It typically presents as asymptomatic, pale to skin-colored, firm, non-follicular papules, most commonly on the neck of elderly individuals. We report a 39-year-old Thai woman with a four-year history of slowly progressive, monomorphic, skin-colored papules on the upper back and chest with few papules on each side of the neck. Histopathology showed thickened collagen bundles with sparse perivascular lymphoid infiltrates in the dermis, and elastin staining revealed a slight reduction of elastic fibers in the upper reticular dermis. Correlating clinical and histological findings, a diagnosis of WFP was established, with the truncal involvement representing an uncommon presentation of this condition.
