“…Further reviews have been published by Mistilis, Wiot, and Nedelman (1963), who found 34 previously reported cases and tabulated the clinical findings in 14 cases of their own, by Lemaire, Blanchon, Emerit, Yean, Tavernier, and Giorgi (1966), who added two cases to 40 found in the literature, and by Kirsh and Brendel (1968).
