An anatomical investigation of alkaptonuria: Novel insights into ochronosis of cartilage and bone

Journal of Anatomy, Volume 246, Issue 6, Page 1053-1074, June 2025.
Examination of an alkaptonuria body highlights the susceptibility of all cartilage types and associated perichondrium to ochronotic pigmentation and the heterogeneity of ochronotic pigment distribution both within and between tissues. In joints, calcified cartilage pigments before non‐calcified cartilage.
