BACKGROUND Sarcoid involvement of the central nervous system is a rare occurrence, with involvement in approximately 5-10% of all cases. Isolated spinal involvement is an even rarer encounter, only 0.3-1% of all cases. These lesions can form compressive nodules leading to myelopathy. In the presented case of cervical sarcoid, the patient required a decompressive procedure to address cord compre...

BACKGROUND A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers. However, only a few published re...

We and other investigators have hypothesised that the CXC chemokine receptor (CXCR)3/CXCR3 ligand biological axis is involved in the formation of sarcoid lung granulomas; however, significant discrepancies in the current literature remain. In an effort to clarify previous conflicting findings, we performed the largest observational study to date of interferon-inducible ELR(-) (lacking the seque...

BACKGROUND T cells recognizing as yet unknown antigens (Ags) are considered to play an important role in the development and perpetuation of the disease process of sarcoidosis. Several studies have shown that T cells that bear a limited T-cell receptor (TCR) repertoire may play an important role in this disorder. However, regarding variable (V) gene repertoire usage, the results differ among va...

however, that sarcoid of the SI joint may be more common than previously thought. A single European study found that isolated pulmonary sarcoid was associated with HLA-B27 [10], making a true association between SpA and sarcoid possible, but this finding has not been replicated and the relatively high prevalence of the two conditions (1:1000 for AS and 0.04–64/1000 for sarcoidosis [7]) makes sp...

Sarcoidosis is a systemic chronic granulomatous disease of unknown cause. Recent investigations revealed that the cytokine profile in inflamed lesions of sarcoidosis is Th1 dominant. To obtain better immunopathologic understanding of sarcoidosis, we examined the expression of IL-12 and IL-18 and their roles in IFN-gamma production in pulmonary sarcoidosis. Sarcoid cases had significantly elevat...

The diagnosis of ocular sarcoid is presumptive in the absence of systemic disease. The association of elevated serum angiotensin-converting enzyme (ACE) levels with active systemic sarcoid has been well described. With a sensitive fluorimetric assay for ACE, we found that five of ten chronic granulomatous uveitis patients without systemic sarcoid had elevated serum ACE levels. None of ten patie...

BACKGROUND The increased risk of cancer in patients with sarcoidosis is well established, but there is little information regarding sarcoid diagnosed during or following cancer. The purpose of this study is to describe and analyze the disease status and events associated with the diagnosis of sarcoid in cancer patients. METHODS At a large cancer center, we identified 64 patients with a pathol...

Equine sarcoid is the most common tumour of horses and accounts for over half of all equine skin tumours. Six types of sarcoid based on gross appearance and clinical behaviour have been described including occult, verrucous, nodular, fibroblastic, mixed and malevolent. Common locations for sarcoid development include the periocular region, ear pinnae, lips, neck, extremities and ventrum (includ...
