Chromaffin system

The chromaffin organ system is a special section of the endocrine system, located deep in the pancreas and as part of the mesenchymal tissue in other parts of the abdominal cavity.

The Chromaffin system was discovered by studying animal tissue. This occurred during medical observations of patients with symptoms of hyperparathyroidism that arose after removal of a hyperplastic parathyroid gland. The first condition for the formation of the Chromaffin system was the presence of a thyroid cell in the stroma of the gland, removed during surgery. Subsequently, the same results were obtained in observations of patients with metastatic lesions of the gland by lung cancer and chronic lithaemic thyropathy. Consequently, the conclusion about the presence of chromaffinoma or chlormacinoma in these tissues turned out to be incorrect. Further research showed that inside the tumor tissue there are indeed cells that represent the beginning of a system with the secretion of specific hormones, but according to histological plan, these neoplasms belong to gland tissues no more than how representatives of the population of the third world, in turn, belong to the privileged countries of the West.
