In a group of 61 patients with SAPHO syndrome involving bone, 8 cases of chronic inflammatory bowel diseases have been observed. 6 cases are considered as Crohn's disease and 2 as ulcerative colitis. 5 patients presented with sacro-iliitis, 4 with palmoplantar pustulosis, 3 with plain psoriasis and 1 with disseminated acne. 4 patients have HLA B27 antigen. These findings bring some evidences to lump SAPHO syndrome with the spondylarthropathies.
