Osteitis Condensans Ilii (OCI) is a benign cause of axial low back pain. Although no clear etiology has been identified, the prevailing theory is that mechanical strain affects the auricular portion of the ilium and causes premature arthritis. The location of the sclerosis has been traditionally confined to the ilium and may give the false impression of sacro-iliac joint involvement. Clinicians must be guided by history, radiographic findings, and laboratory studies in differentiating OCI with other disorders; furthermore additional causes of low back pain including metastatic disease and ankylosing spondylitis must be ruled out. Treatments for the condition are primarily conservative (therapies, non-steroidal anti-inflammatory medications, and steroid injections), with surgical resection being reserved for refractory cases.

Interleukin (IL)-23 plays a central role in the orchestration of inflammatory responses. Produced by dendritic cells and macrophages, this cytokine promotes the protection of the host against mucosal pathogens through the induction of IL-17 and related cytokines by lymphoid cells. Preclinical disease models and association studies in humans have also clearly demonstrated the implication of IL-23 signalling pathway in inflammatory diseases. Indeed, this cytokine is now considered as a major therapeutic target in immune-based pathologies such as psoriasis, ankylosing spondylitis or Crohn's disease. Furthermore, in the context of inflammation-related cancer, IL-23 is thought to contribute to tumorigenesis and progression to metastatic disease. Herein, we review our current understanding of IL-23 regulation at the transcriptional and post-transcriptional levels. We discuss the relevance of these findings in the context of infection, chronic inflammation and cancer.

Xanthomatous sialadenitis (XS) is rarely reported. Here we report XS in a case of HLA-B27-positive ankylosing spondylitis showing also anti-MAG-positive polyneuropathy with IgM-kappa dysimmunoglobulinemia/paraproteinemia, lung small cell carcinoma and buccal squamous cell carcinoma (SCC). The lesions were identified in submandibular and labial minor salivary glands of a neck dissection specimen (made during a buccal 1.7 cm large SCC resection procedure). The oral SCC was resected at 8 months after the diagnosis of the lung small cell carcinoma (with skull dome metastases, revealed by a superior cava syndrome) and at 2 months after radiotherapy. The microscopic XS-lesions consisted in multifocal accumulations of CD68-positive macrophages. Plasmocyte-abundant foci (CD138-positive) were extra-xanthomatous (atrophic parenchyma, zones of adipose involution). CD138 was also expressed in ductal cells and in acini (focally). In conclusion, we report XS of submandibular and labial minor salivary glands, occurring in the context of a HLA-B27-positive ankylosing spondylitis, polyneuropathy with IgM-kappa dysimmunoglobulinemia and anti-MAG antibodies in a case of small cell lung carcinoma (treated by radio-chemotherapy) and oral SCC.
