WebChromogranin A (CHGA) is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocine cells. CHGA is a precursor to three biologically active peptides: vasostatin, pancreastatin, and … WebBackground: Malignant mixed corticomedullary adrenal tumors (MCMTs) are extremely rare, with limited cases reported in the literature. The pathophysiology of malignant MCMTs is not well understood; the most prevailing theories are that it is a composite tumor of embryologically derived mesodermal (adrenal cortex) and neural crest (medulla) origin, …

Pathology Outlines - Chromogranin
WebThe markers most commonly used in routine histopathology have been the secretory granule proteins chromogranin and synaptophysin, and the cytosolic enzyme neuron-specific enolase (NSE).16 As is well known, of these, chromogranin is the most specific, but, unfortunately, its sensitivity is about 80% to 90% ( Fig. 15.2 ). WebCgA, NSE and Syn were positive in 10,10 and 7 cases respectively. RESULTS Chromogranin A ( CgA ) positive GC was demonstrat - ed in 85 cases ( 45.0 % ). Immunohistochemically, the tumor cells were positive for EMA, PCK, NSE, Syn and CgA . CGA Progressive Wall Reduction means the CG gets progressively lower throughout the … WebEl análisis de suero con cromogranina A es una ayuda diagnóstica muy útil, ya que los tumores neuroendocrinos son tumores sutiles, porque son difíciles de diagnosticar en las etapas iniciales debido a su pequeño tamaño, crecimiento lento y síntomas no específicos, que, cuando están presentes, pueden incluir : diarrea; náuseas; personalized print on demand journal
