Report of a case of subcutaneous sarcoidosis

In this article we present a 53-year-old lady, who had progressive indurated skin lesions on her both forearms since 3 months ago, without skin discoloration. Chest x-ray showed parahilar lymphadenopathy, in high resolution CT (HRCT) scan evaluation multiple lymph nodes in upper and middle mediastinum were reported. Angiotensin converting enzyme (ACE) level was increased to 81 (normal 5-5...

Morphology and histochemistry of helicine arteries in the corpora cavernosa penis of mice.

The epitheloid modified walls of helicine arteries are built of tightly arranged specialized smooth muscle cells (epitheloid cells). They are polygonal in shape, but do not branch out. The number of myofilaments is markedly reduced, whereas cell organelles are well developed (mitochondria, Golgi regions, rough endoplasmic reticulum). Myofilaments are gathered to bundles with no orientation as t...

معرفی یک مورد بیمار مبتلا به سارکوییدوز با تظاهرات بالینی مشابه سندرم شوگرن

    Introduction: Sarcoidosis is a chronic granulomatous disease of unknown origin characterized by the presence of non-caseating epitheloid cell granulomas in multiple organs such as lymph nodes, lungs, spleen, liver, skin, and salivary and lacrimal glands. The diagnosis is established when clinical and radiologic findings are supported by histologic evidence of non-caseating granulomas. Sarco...

Collagen nature of asteroid bodies of giant cells in sarcoidosis.

STAR-sHAPED INCLUIONS have been observed in multinucleated giant cells as far back as 1890.1 Perhaps the most comprehensive study of the asteroid bodies, as seen under the light microscope is that of Cunnngham' who e d in 1951 that "in tests for collagen, Masson's trichrome stain and Mallory's connective tissue stain showed negative results. Wilder's stain for reticuhlm wa uni negative. Cunning...
