Although Masson originally called the proliferation in question 'intravascular vegetant hemangioendothelioma' the currently preferred designation is 'intravascular papillary endothelial hyperplasia' (IPEH) or, more simply, 'Masson's lesion'."; Dhom G : Geschichte der histopathologie, pp. 50-54; Moore S et al.: The career and influence of Pierre Masson (1880-1959), Int J Surg Pathol., 2001, 9(3), 231-236: "Pierre Masson was one of the towering figures of Pathology in the 20th century, in particular in the field of histopathology of the human tumors. These innovative techniques, applied with exacting detail, combined with his talent for observation and his scientific perspicacity, produced remarkable results"; Hajdu SI & Darvishian F : Landmarks in history of cancer, part 5, Cancer, 2013, 119 (8), 1450?1466: ; Steffen C: C.L.
