IDOMED and Instituto Yduqs, unable to get Brazilian doctors to notice a medical curriculum built entirely around white skin, had Artplan diagnose racism itself — publishing a clinical-looking reference book of 20 fictionalized 'pathologies' modeled on real Black patients' testimony
the problem
Medical reference materials show disease presentation only on white skin
background
Brazilian medical schools, like most worldwide, built their diagnostic reference materials around one default patient: white skin. Rashes, cyanosis, jaundice, and dozens of other textbook-classic presentations were illustrated almost exclusively on light skin, a well-documented gap in dermatology and general medical training globally. In Brazil, where roughly half the population is Black or mixed-race, doctors trained this way misread or delayed diagnosis in Black patients — the exact failure IDOMED and Instituto Yduqs's diversity program was created to address.
Rather than run an awareness campaign, agency Artplan built Nigrum Corpus — Latin for 'Black body' — a hardback publication designed exactly like a clinical reference text, describing 20 fictionalized pathologies grounded in hundreds of hours of research and real patient testimony, paired with a short film following a Black patient's treatment in a Brazilian hospital. The device borrows medicine's own visual authority — typography, anatomical plates, dosage charts — to diagnose the field's blind spot in its own language.
what everyone would do
The standard response to a diversity gap in professional training is an awareness campaign — a poster, a lecture, a mandatory sensitivity module telling doctors that skin-tone bias in diagnosis exists and urging them to remember the exception. That approach asks already-overburdened clinicians to consciously override a default they were trained on for years, every time, with no change to the reference material itself — the textbook still only shows the rash on white skin, so the bias remains built into the tool doctors actually reach for under time pressure.
what they saw
IDOMED, Instituto Yduqs and Artplan saw that doctors already trust a specific visual and textual format — the clinical reference text, with its anatomical plates, typography, and dosage charts — as the authoritative source of diagnostic truth, and that trust in the format itself was the actual lever, not the content of any individual awareness message. Rather than tell doctors about the gap in a format they'd file away as an HR initiative, they built the missing reference material in medicine's own visual language, making the profession's blind spot legible using exactly the authority structure the profession already deferred to.
the move
Instead of a diversity campaign, IDOMED, Instituto Yduqs, and Artplan produced a book and short film that adopt the exact visual grammar of a medical textbook — anatomical illustration, typography, dosage charts — to present racism in Brazilian healthcare as a set of diagnosable 'conditions,' built from real patient testimony and research rather than invented anecdotes.
why it works
By adopting the precise visual grammar doctors already associate with clinical authority — the anatomical illustration, the dosage chart, the textbook typography — Nigrum Corpus borrowed the credibility of the format itself rather than asking to be believed on its own terms, so the same instinct that makes a doctor trust a real diagnostic reference carries over to trusting this one. Grounding the twenty fictionalized 'pathologies' in real patient testimony and hundreds of hours of research, rather than composite anecdotes, meant the book could withstand the same scrutiny a doctor would apply to any other clinical reference, which is likely why it was adopted as supplementary teaching material at dozens of universities rather than being dismissed as an advocacy pamphlet. Because the format itself does the persuasive work, the project reaches doctors inside their existing professional routine — being assigned or shelved alongside other reference texts — rather than requiring a separate, competing claim on their attention the way a standalone awareness campaign would.
the payoff
Per agency and independent trade-press reporting, the book has been adopted as supplementary teaching material by roughly 32 Brazilian universities, reportedly reaching over 9,000 medical students across 10-plus states, and was shared with Brazil's Ministry of Health — though being shared with the ministry is not the same as an official protocol change, and these figures come from agency and press coverage rather than an independent academic audit. The project became the first Brazilian creative work to win two Cannes Lions Grand Prix, in Industry Craft (2025) and Glass: The Lion for Change (2026).
where it breaks
This mechanism depends on the target profession having a genuine, specific format it already extends authority to — medicine's clinical-reference-text conventions are distinctive and widely recognized, but a field without an equally trusted, recognizable documentary format has no equivalent authority to borrow, and an imitation format the audience doesn't already defer to would read as a gimmick rather than a diagnosis. It also depends on the underlying content being rigorous enough to survive the scrutiny the borrowed format invites — a project built on invented or unverified anecdotes dressed in clinical typography would be exposed the moment a skeptical reader checked its sourcing, which is presumably why the team grounded the twenty pathologies in real patient testimony rather than composite fiction. And because the case's own outcome figures — 32 universities, 9,000+ students, sharing with the Ministry of Health — come from agency and press reporting rather than an independent academic audit, and being shared with a ministry is not the same as a formal protocol change, this should be read as a strong signal of adoption and reach rather than documented proof of a measured reduction in Black patients' diagnostic delays.
what came after
Nigrum Corpus is cited in Brazilian advertising and medical-education circles as a model for using the exact format a profession already trusts to indict that profession's own blind spot, and has continued into hospital exhibitions in Rio de Janeiro.
