In 1887, Majocchi for the first time observed, and in 1896 for the first time published, a report of a hitherto undescribed dermatosis, "purpura annularis teleangiectodes," and enlarged on it, in 1898, in the Archiv für Dermatologie und Syphilis, as a contribution to the Festschrift for Pick. In a memoir to the Royal Academy of Sciences of Bologna, in 1904, he collected reports of his cases, seven in all, and published them in book form in honor of Pick's anniversary. In 1912, at the International Congress of Dermatology and Syphilis at Rome, he reported a further series of six cases,1 so that the first observer of this unrecorded skin malady had a collection of thirteen cases to report within a period of twenty-five years.
This rather small number evidences the comparative rarity of the disease. It was fully eight years before another observer, Brandweiner, published an exhaustive paper based
