White fibrous papulosis of the neck in three Sicilian patients.

Three patients, two females and one male, presented with white fibrous papulosis of the neck. This condition is characteristically located on both sides of the neck; however, it also appears on the upper sternal region, with a necklace-like configuration, in the two female patients, aged 72 and 78 years, respectively. A differential diagnosis was carried out with respect to other dermatoses that show a similar skin aspect, and to the pseudo-xanthoma elasticum-like papillary dermal elastolysis. This is because this condition, as well as fibrous papulosis, can be interpreted as a clinical-histological variant of the same process of cutaneous ageing. However, environmental factors can play a role in the aetiopathogenesis of fibrous papulosis in the Sicilian population.
