Fibroelastolytic papulosis of the neck (FEPN) consists of two disorders: white fibrous papulosis of the neck (WFPN) and pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE). The neck and supraclavicular areas are frequently involved; however, axillary involvement is significantly rarer, especially for white fibrous papulosis. Herein, we present an unusual case of white fibrous papulosis of the axillae, in addition to the neck, in a Caucasian woman. White fibrous papulosis of the neck (WFPN) presents as many white, round, discrete, asymptomatic papules, approximately 2-3 mm in diameter, on the neck. It is a rare condition, first described in Japan that tends to affect elderly individuals. It belongs to the broader category of fibroelastolytic papulosis of the neck (FEPN). FEPN has two subcategories, pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE) and WFPN, the latter of which is present in our patient. It is rare for white fibrous papulosis to occur in the axillae, as it typically occurs on the neck, but such is the case for our patient. Herein, we present an unusual case of white fibrous papulosis of the axillae, in addition to the neck, in a 65-year-old Caucasian woman, which had been present for several years at the time of presentation.
