Malignant Hidroacanthoma simplex

“…We have not included some cases reported in the literature as malignant hidro acanthoma simplex [ 1,18,19], because in our opinion, they were either not examples of poroma or they were composed of large aggregations of neoplastic cells in the dermis, and therefore they are better interpreted as porocarcinomas rather than malignant hidroacanthoma simplex.…”

Porocarcinome eccrine

“…Depuis la première description de Smith et Coburn [15] en 1956 sous l'appellation d'hidroacanthome malin, de rares cas de po rocarcinome ont été rapportés isolément [1][2][3][4][5]7,8,[10][11][12][13]15,16]. Récemment, la lit térature s'est enrichie d'une série de 27 cas rapportés par Schaw et al [14] et de 18 cas par Mehregan et al [9].…”

“…Morphological, histochemical, and enzyme-histochemical studies have identified the lesion as a form of intraepidermal ec crine poroma [2,3], Malignant transformation of hidroacan thoma simplex has been reported infre quently [1,4,5,6], with only isolated ultrastructural reports [6].…”
