  • Title: Eruptive vellus hair cyst in patients with chronic renal failure.
    Author: Mieno H, Fujimoto N, Tajima S.
    Journal: Dermatology; 2004; 208(1):67-9. PubMed ID: 14730241.
    Abstract:
    Two cases of eruptive vellus hair cysts associated with chronic renal failure are reported. Histologically the lesions of both cases showed cystic structures in the dermis lined by squamous epithelium which contained varying amounts of vellus hair shafts. Immunohistochemical studies using monoclonal anti-AGE (advanced glycation end product) antibody demonstrated that keratinous materials within the cystic structures were immunoreactive to the antibody, whereas those of cystic lesions (epidermal cyst, eruptive vellus hair cyst, steatocystoma multiplex, trichofolliculoma and trichilemmal cyst) seen in otherwise healthy individuals were negative. Because it has been reported that plasma and skin levels of AGE are elevated in renal failure patients, AGE-modified keratinous materials may be associated with the formation of cystic structures by stimulating the occlusion of the epithelium.
