A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

RHEUMATOLOGY + DERMATOLOGY

YEAR 2 | PAGE 26B - AUTOIMMUNITY, VASCULITIS + SKIN MORPHOLOGY / MALIGNANCY

RHEUM / DERM FRAME

RHEUM: PATTERN OF JOINTS + SYSTEMIC ORGANS + ANTIBODIES/COMPLEMENT -> MECHANISM. DERM: PRIMARY LESION -> COLOR/SCALE -> DISTRIBUTION -> SYSTEMIC CLUES -> BIOPSY/TEST. Describe what you see before naming it.

B. RHEUMATOLOGY + DERMATOLOGY VIDEOS — AUTOANTIBODY + MORPHOLOGY CHECK

- Use antibodies as probability-shifting evidence after the phenotype: anti-CCP for RA; dsDNA/Sm and complement for SLE; ANCA patterns for vasculitis; do not diagnose from a positive lab alone. - Know the inflammatory-back-pain pattern and the seronegative spondyloarthropathy cluster; link enthesitis, uveitis, psoriasis and IBD deliberately. - Describe skin lesions with primary morphology, scale/secondary change and distribution before choosing a diagnosis; recognize mucosal/systemic involvement as a danger clue. - Know the red flags for necrotizing infection, SJS/TEN, meningococcemia/purpura, melanoma and rapidly progressive vasculitis.
