A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen). When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma.
Micrograph highlighting the sustentacular cells in a paraganglioma. S100 immunostain. A sustentacular cell is a type of cell primarily associated with structural support, they can be found in various tissues.
A gangliocytic paraganglioma is a rare tumour that is typically found in the duodenum and consists of three components: (1) ganglion cells, (2) epithelioid cells (paraganglioma-like) and, (3) spindle cells (schwannoma-like).
The S100 proteins are a family of low molecular-weight proteins found in vertebrates characterized by two calcium-binding sites that have helix-loop-helix ("EF-hand-type") conformation. At least 21 different S100 proteins are known. [1] They are encoded by a family of genes whose symbols use the S100 prefix, for example, S100A1, S100A2, S100A3.
Symptoms include tremor, anxiety, palpitations, sweating, altered mental status (confusion), dizziness, and blurred vision. [128] A retrospective analysis of beta blocker found that some beta blocker use may cause people to more prone to hypoglycemia and not experience these symptoms, which could delay the diagnosis.
S100A7 is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are ...
Medically unexplained physical symptoms (MUPS or MUS) are symptoms for which a treating physician or other healthcare providers have found no medical cause, or whose cause remains contested. [1] In its strictest sense, the term simply means that the cause for the symptoms is unknown or disputed—there is no scientific consensus .
Pediatric GISTs are treated differently from adult GISTs. Although the generally accepted definition of pediatric GIST is a tumor that is diagnosed at the age of 18 years or younger, [46] "pediatric-type" GISTs can be seen in adults, which affects risk assessment, the role of lymph node resection, and choice of therapy.
