Myxofibrosarcoma is one of the most frequent soft tissue tumours in elderly patients, mostly arising in the extremities. Grade I lesions are only locally aggressive whereas grade II and grade III lesions have metastatic potential. The differential diagnosis contains several other (benign) myxoid soft tissue tumours.
Endocrine gland. 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.
Ductless glands are called endocrine glands. Glands receive signals from the brain to release useful fluids. Endocrine glands release hormones directly into the bloodstream. Hormones are the chemical messengers which facilitate the communication between the brain and the organs. As the nervous system uses nerves to send the required information, the glands in the human body use blood vessels as information channels. Here's an overview of the endocrine system.
