ABSTRACT
Los desórdenes perforantes actualmente incluyen a la enfermedad de Kyrle, la elastosis perforante adquirida serpiginosa, la colagenosis perforante reactiva adquirida y la foliculitis perforante. Antes se consideraban entidades diferentes, pero debido a los hallazgos similares en la clínica e histopatología, se engloban dentro de este término unificador. Se manifiestan como pápulas y/o nódulos que presentan un tapón queratósico central. Su causa es desconocida, sin embargo, se las ha relacionado con distintas patologías sistémicas como la diabetes mellitus y la enfermedad renal crónica, entre otras. Se presentan dos casos de dermatosis perforante adquirida tipo colagenosis perforante reactiva, en un hombre de 69 años con antecedentes de diabetes mellitus tipo II y cirrosis hepática secundaria a infección por virus de hepatitis C y una paciente de 62 años con antecedente de diabetes mellitus tipo II.
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.
