Conclusion
This clinical encounter is an opportunity to differentiate spondyloarthritis from skeletal hyperostosis. Our experience highlights retinoid hyperostosis, a condition nearly identical to diffuse idiopathic skeletal hyperostosis, as a rare cause of axial pain. Although uncommon, this diagnosis is important to make, because if caught early, cessation of isotretinoin can be recommended, and musculoskeletal symptoms can potentially be reversible.10
