White Fibrous Papulosis of the Neck: A Case Report

Abstract

White fibrous papulosis of the neck is a rare entity, with a benign course and unknown pathogenesis. It is clinically characterized by the appearance of firm, persistent, usually asymptomatic, non-follicular papules located on the neck. We present the case of a 72-year-old patient who presented pruritic lesions on the neck whose biopsy was compatible with this entity.

White Fibrous Papulosis of the Neck in a 70-Year-Old Female: A Case Report

“…To confirm the clinical diagnosis of WFPN, a biopsy is performed. It is characterized histologically by the presence of fibroelastolytic alterations in the papillary dermis, with a decrease or absence of elastic fibers [ 5 - 7 ]. Given that this condition impacts the neck, it is also imperative to differentiate WFPN as a benign ailment characterized by the absence of lymph node pathology [ 8 ].…”

“…These clinical features suggest the following differential diagnoses: PXE-PDE, PXE, acrochordons, fibrofolliculoma, trichodiscomas, Buschke-Ollendorff syndrome, and cutis rhomboidalis nuchae (Table 1) [2,4,5,[9][10][11][12][13]. PXE papules resemble WFPN owing to their white, discrete appearance, which can occasionally merge, creating a "cobblestone" or "chicken skin" texture [14].…”
