Escharotic agents, Fred Mohs, and Harry Hoxsey

Peer-reviewed dermatologic-history article confirming bibliographic metadata directly via PubMed (title, author, journal, volume/issue/pages, DOI, PMID all fetched and confirmed from the PubMed record itself). Situates Hoxsey's caustic escharotic paste within the wider historical tradition of escharotic cancer treatments alongside Fred Mohs's chemosurgery paste. The full-text abstract page (jaad.org) returned HTTP 403 to direct fetch, so no verbatim quotation from the article body is used in this bundle; only the confirmed bibliographic citation and its well-established general historical framing (escharotics are non-selectively caustic) are used, cross-supported by the American Cancer Society source.
