As a clinician, Hoffmann is the author of capital works in the field of dermatology, where he histologically studied a whole range of skin processes (dermatofibrosarcomatosis, nevo-epitheliomas); he created and substantiated the concept of "esophylaxis" as an expression of a special protective function of the skin (Bonn, 1919); in the field of syphilidology, in a whole series of works, he revealed the practical significance of early salvarsan therapy; among other things, he proposed sodium thiosulfate as a remedy against side effects of salvarsan; he described a fundamentally important case of syphilis infection through cadaveric material (1926). Hoffmann's most important works: "Die nach innen gerichtete Schutz- u. Heilwirkung der Haut (Esophylaxie) mit besonderer Berücksichtigung der Tuberkulose" (Berlin, 1927); together with F. Schaudinn—"Über Spirochaeta pallida bei Syphilis u. die Unterschiede dieser Form gegenüber anderen Arten dieser Gattung" (Berliner klinische Wochenschrift, 1905, No. 22–23); together with S. Prowazek—"Untersuchungen über die Balanitis- u. Mundspirochaeten" (Centralblatt für Bakteriologie, 1. Abt., Orig., B. XLI, 1906).
