The glands which consist of both endocrine and exocrine gland system are called mixed glands. For example: pancreas, male gonads, etc.
A mixed gland is a gland which has both endocrine and exocrine functions. The exocrine component has ducts, through which its secretions pass. The pancreas is a gland with both endocrine (insulin production) and exocrine (production of digestive enzymes) functions.
