Isotretinoin-induced skeletal hyperostosis

Area of Science:

• Rheumatology
• Dermatology
• Radiology

Background:

• Isotretinoin is a common treatment for severe acne.
• Skeletal hyperostosis has been reported in association with isotretinoin use.
• This condition radiographically resembles diffuse idiopathic skeletal hyperostosis.

Purpose of the Study:

• To describe a case of skeletal hyperostosis in a patient treated with isotretinoin.
• To highlight the association between isotretinoin therapy duration and skeletal hyperostosis.
• To inform rheumatologists about this potential adverse effect.

Main Methods:

• Case report of a 29-year-old male with non-inflammatory back pain.
• Review of radiographic findings.
• Correlation of symptoms with past isotretinoin therapy for acne.

Main Results:

• The patient presented with skeletal hyperostosis, predominantly affecting the spine.
• The severity of skeletal hyperostosis appears to correlate with the duration of isotretinoin therapy.
• Radiographic findings were similar to diffuse idiopathic skeletal hyperostosis.

Conclusions:

• Rheumatologists should be aware of isotretinoin-induced skeletal hyperostosis in young patients with musculoskeletal symptoms.
• This condition is a potential adverse effect of isotretinoin therapy for acne.
• Early recognition and awareness can aid in the assessment of patients with unexplained radiological abnormalities.
