Two cases of synovitis, acne, pustulosis, osteitis--SAPHO syndrome.
Synovitis, acne, pustulosis, osteitis (SAPHO) syndrome is rare with yet unknown prevalence. The difficulty in recognizing the syndrome is due to the very wide diversity of its signs and symptoms, the lack of skin manifestations in many cases and to confusion in medical terminology in describing this syndrome. In this paper, we present two cases with characteristic bone lesions in bone scan and in radiology images that are considered to be SAPHO syndrome. In the first case the characteristic bone single photon emission tomography scan findings in a patient with spine involvement supposed by bone biopsy but were not followed by characteristic skin manifestations. The point of interest of this case lies on the significant improvement of both symptoms and scintigraphic findings after treatment with biphosphonates. In the second case the diagnosis was also based on the characteristic bone scan findings, although the patient referred to us for staging of prostate cancer. Detailed history and clinical examination revealed skin manifestations of the syndrome.
