In 1956, one year after their report on livedo reticularis with summer ulceration, Feldaker and colleagues wrote again about the very same condition and compared their observations in the 12 patients described previously [18] (diagnosed by them as livedo reticularis with summer ulcerations) with 18 patients who also had developed ulcers mainly in wintertime (Figs. 3A–C). [7]

The authors concluded that "there was no difference in the appearance or location of the ulcerations occurring on the legs, ankles, or feet." Only five of the 18 patients with ulceration occurring predominantly in winter were biopsied. In four of them, there was "thickening of the wall of arterioles of the cutis and subcutaneous tissue and occlusion of these vessels [ . . . ]" and in two of those "the arterioles revealed occlusion by a thrombus." The authors concluded that "the histopathologic picture of summer ulcerations or winter ulcerations with livedo reticularis reveals no essential difference in the type or degree of vessel involvement." They also acknowledged that, "occasionally a patient with primarily winter ulcerations would develop ulcerations during summer months."

In brief, Feldaker and colleagues stated that the findings clinical and histopathologic in "livedo reticularis with ulceration in winter" or "in summer" are very similar even though they failed to state straightforwardly that patients of both groups had essentially the same disease. They continued to use the term livedo reticularis when, in fact, they were referring to bizarre shaped, branched erythema typical of livedo racemosa (see also livedo racemosa).
