Treatment is usually curative with wide-margin surgical excision but due to the malignant nature of these tumors, recurrence should be considered and regular monitoring is recommended. 1  Gianella P et al (2012) Primary cutaneous undifferentiated round cell tumor with concurrent polymyositis in a dog.

Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.The hypothalamus and pituitary gland are neuroendocrine organs.Local chemical messengers, not generally considered part of the endocrine system, include autocrines, which act on the cells that secrete them, and paracrines, which act on a different cell type nearby.he hypothalamus and pituitary gland are neuroendocrine organs.

When the blood glucose is elevated, the pancreas secretes insulin and when the blood glucose falls, it secretes glucagons. 3) nervous system to glandâSome glands secrete hormones in direct response to the nervous system. For example, the adrenal medulla secretes a hormone in response to sympathetic nerve impulses.For information on specific endocrine glands, see the table on the following pages. All body functions are influenced by the endocrine glands; there are no processes that are NOT affected by hormone signaling.arget cells are specific to the hormone; a hormone specific to a target cell can only affect that target tissue because of the presence of receptors for the hormone on the target cells. Some endocrine glands are so complex and so specific that certain sections of the gland produce different hormones.
