To the Editor:—It would seem reasonably clear that the way effectively to dispute or confirm the conclusions of the study by Dr. Halpryn and me is not by tendentious pronouncements but by a dispassionate systematic analysis of a corresponding sample. However, even prior to such an analysis, if Dr. Caro chooses to call a lesion of the type depicted in Figure 5 of our paper a simulated rather than a genuine basal-cell carcinoma, then the source of his disagreement becomes clear. The main point of the paper, which apparently has not been thoroughly appreciated, is that a dermal tumor—a sclerosing angioma—may induce hyperplastic and neoplastic changes. Herein is a basic pathogenetic phenomenon that deserves further exploration.
