This book offers an overview of the clinical applications of PET/MR imaging through a case-based format. This book presents the morphology of different non-tumoral lesions of the testis. Sarcoidosis is a systemic granulomatous disease of unknown etiology, characterized by the formation of non-necrotizing (“noncaseating on gross pathology”) granulomas. The hallmark of sarcoidosis is the presence of noncaseating granuloma, a cluster of macrophages, epithelioid cells, mononuclear cells, and CD4 + T cells with a few CD8 + T cells in the peripheral zone.1, 2 The etiology of sarcoidosis is not known with certainty despite decades-long effort. Pathognomonic. There is controversy about their composition. A granuloma, also granulomatous inflammation, is a distinctive histomorphologic finding.. Granulomas can be elusive to the novice. The histologic hallmark of sarcoidosis is noncaseous granulomas composed of a central core of histiocytes, epithelioid cells, and multinucleated giant cells surrounded by lymphocytes, scattered plasma cells, and varying quantities of fibroblasts and collagen in the periphery . Clinical and radiologic correlation is required. At low power markedly distorted parenchyma is highlighted by seeing the minor component of unaffected cores [parallel to double headed arrowsD] (Row 1 Left 20X). “Pathology of granulomatous diseases: foreign body granulomas”.

Histologically, the lesions characteristically demonstrate an absence of a necrotic component, except in rare cases (so-called "necrotizing sarcoid granulomatosis"). This report described a valuable case in which pathology of VATS specimens collected from the lungs with honeycomb-like structures on chest CT showed granulomas in the membranous bronchiole walls (Fig. This is a new edition of a classic textbook of oral pathology and oral medicine for dental students and candidates for postgraduate dentistry exams.

Histologically, granulomas are the main feature of this disease process and can be found in almost any organ, although the lung and hilar lymph nodes are most common. The role of pathology in the diagnosis of sarcoidosis is identification of granulomas in tissue specimens and performance of studies to exclude known causes of granulomatous inflammation. Comparison of pulmonary sarcoidosis granuloma histology to other granulomatous lung diseases.
