Steroidogenic Factor 1 (SF1) Immunohistochemical Stain Is Sensitive and Specific for the Cytopathologic Identification of Intrapancreatic Ectopic Splenic Tissue

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Accessory spleens result from failure of splenic fusion during development and are occasionally located in the pancreatic tail, radiographically appearing as solid or solid/cystic lesions. Fine needle aspiration (FNA) easily identifies accessory spleens in most samples based on architecture and using CD8 to highlight splenic ...

Chromogranin A processing in sympathetic neurons and release of chromogranin A fragments from sheep spleen [PDF]

open access: yesFEBS Letters, 1992
Chromogranin A (CGA) has been localized to the large dense cored vesicles (LDV) of sympathetic neurons. SDS‐PAGE and immunoblotting of soluble LDV proteins from ox and dog adrenergic neuronal cell bodies, axons and nerve terminals, revealed an increasing number of CGA‐immunoreactive forms, consistent with proteolytic processing during axonal transport.

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

CHROMOGRANIN-A IN THE DIAGNOSIS OF PROSTATE CANCER

open access: yesИсследования и практика в медицине, 2015
The principal marker of neuroendocrine differentiation (NED) is chromogranin A (HGA). The purpose of this work is to determine the role of NED in diseases of the prostate gland by the level of HGA.Materials and methods.

Chromogranin A (CgA) in adrenal tumours

open access: yesEndokrynologia Polska, 2013
Adrenal tumours can produce specific hormones and cause characteristic symptoms. The majority of adrenal incidentalomas are clinically silent, but some may be malignant or pose other potential threats to life. Chromogranin A (CgA) is the main, nonspecific marker of neuroendocrine tumours (NET).
