“…13,14 It has been suggested that the transepithelial elimination of collagen is simply a reaction pattern related to chronic rubbing or scratching in a subset of pruritic patients. 15,16 ARPC lesions usually resolve when the pruritus is controlled. Moreover, insufficient blood supply as a result of microangiopathy and polymorphonuclear leukocytes has been suggested to be a predisposing factor for focal necrobiosis of tissue.…”

“…El prurito causaría rascado que provocaría microtrauma. Este microtrauma produciría alteraciones en las fibras colágenas de la dermis papilar provocando su eliminación transepidérmica 10 . Otra teoría propuesta para los casos asociados a la diabetes mellitus, propone que la microangiopatía produciría hipoxia y prurito que dañaría al colágeno 11 , además el mayor estrés oxidativo y la glicosilación produciría entrecruzamiento de éste 12 .…”

“…Las enfermedades que más se asocian a la colagenosis perforante reactiva adquirida son la diabetes mellitus y la insuficiencia renal crónica [5][6][7][8][9][10][11][12][13][14][15] , ambas patologías presentes en nuestras pacientes. En un estudio inglés hecho en una población de insuficientes renales crónicos en hemodiálisis, se demostró que 11% presentaba colagenosis perforante reactiva adquirida 15 .…”

“…The patient with hyperparathyroidism had also nephropathy and liver dysfunction. Two of the 3 patients described with associated hypothyroidism had also diabetes mellitus and the third had neurodermatitis, whereas Thiele-Ochel et al [9]observed a patient with APD due to atopic dermatitis without any other underlying disease. Bank et al [10]reported APD in an intravenous drug abuser with AIDS and end-stage renal disease.…”

“…Different treatments have been supposed with different results: topical or intralesional steroids, UVB, bath-psoralen UVA therapy [9], topical and systemic retinoids [30], systemic antihistamines and allopurinol [31, 32]. Krüger et al [31]reported on 2 women with APD associated with hyperuricaemia, diabetic condition and mild renal insufficiency.…”
