[Bone condensation and enterocolitis: SAPHO syndrome. Apropos of a case]. / Condensation osseuse et entérocolite: un SAPHO. A propos d'une observation.

A new case of SAPHO syndrome with lesions confined to the spine and concomitant enterocolitis reported. Only eight cases of this rare combination have been published to date. Bone involvement consisted in sclerosis of vertebral bodies of T10 and T11, raggedness of the vertebral plateaux from T7 to T10, and thick syndesmophytes bridging the vertebrae from T7 to T11. Erythrocyte sedimentation rate was 108 in one hour. Systemic corticosteroids were given after failure of nonsteroidal antiinflammatory agents and recurrence of iritis. Pain resolved promptly and the erythrocyte sedimentation rate returned to normal. This case is unusual both because this combination of diseases is rare and because virtually complete resolution of vertebral sclerosis was noted after one year of corticosteroid therapy. Possible relationships between the SAPHO syndrome and the group of spondylarthropathies are suggested and discussed.
