JUAREZ VILLANUEVA, L et al. Reactive perforating colagenosis: Report of two cases. Rev. argent. dermatol. [online]. 2016, vol.97, n.3, pp.47-57. ISSN 1851-300X.

Perforating disorders currently include Kyrle's disease, serpiginous perforating elastosis acquired, the acquired reactive perforating colagenosis and perforating folliculitis. Previously they were considered different entities, but due to similar findings in clinical and histopathology are now included within this umbrella term. The clinical findings are papules and / or nodules with a central keratotic plug and pruritus is the predominant symptom. It causes are still unknown; however they have been associated with various systemic diseases such as diabetes mellitus and chronic renal disease, among others. We report two cases of reactive perforating collagenosis one in a 69-year-old man with a history of type II diabetes mellitus and liver cirrhosis secondary to infection with hepatitis C and the other one in a 62-year-old woman with type II diabetes mellitus.
