Twelve cases of necrotizing sarcoid granulomatosis are presented as a retrospective study. The population of patients consisted of ten women and two men, with an average age of 50 years. Nine patients initially had a variety of pulmonary and nonpulmonary complaints, while three were asymptomatic. Chest roentgenograms demonstrated bilateral nodules in seven patients, solitary nodules in four, an...

BACKGROUND YKL-40, a growth factor for fibroblasts and vascular endothelial cells, is secreted by macrophages and neutrophils. Elevated serum YKL-40 is found in patients with diseases characterized by inflammation, tissue remodelling and ongoing fibrosis. The aim was to evaluate whether macrophages and giant cells in the granulomatous sarcoid lesions of patients with pulmonary sarcoidosis produ...

Sarcoidosis or sarcoid reactions, which appear as FDG-avid lesions in oncologic patients, need to be differentiated from disseminated malignancies. We aimed to promote awareness of development of sarcoidosis or sarcoid reactions after antineoplastic therapy to avoid diagnostic errors with FDG-PET/CT findings and assess the utility of FDG-PET/CT for follow-up. We retrospectively reviewed radiolo...

BACKGROUND AND OBJECTIVE A disintegrin and metalloproteinase (ADAM) 33 is a susceptibility gene associated with inflammatory lung and skin diseases. It is selectively expressed in mesenchymal cells, and its metalloprotease activity has been linked to angiogenesis and tissue remodelling. A soluble form of ADAM33 (sADAM33) has been identified in the bronchoalveolar lavage fluid (BALF) of asthmati...

treatment of sarcoids is often challenging, due to the variable clinical presentation of lesions and the frequent local recurrences. in this article, both the surgical and the non-surgical treatment of equine sarcoids are reviewed. it is generally accepted that the prognosis is worse if unsuccessful attempts have been made previously. Therefore, the best available treatment option should always...
