White fibrous papulosis of the neck: A case report

Abstract

To the Editor, White fibrous papulosis of the neck (WFPN) which is first described by Shimizu et al. in 1985, is characterized by multiple, confluent, 2-3 mm in diameter, asymptomatic smooth papules. These whitish papules are located on the neck and back and independent from hair follicles 1,2 and also the upper sternum, nape, and the upper arm may be affected. 3 WFPN is generally reported in patients older than 60 years, and the age of the youngest case in the literature is 26 years. 4 Lesions increase progressively and no regression is seen over time. The pathogenesis of WFPN is unknown, besides the studies suggest that age and sun-related damages may be indicative factors for WFPN. Most of the patients have no history of prolonged sun exposure or similar lesions in the family.
