Pineocytoma, is a rare, benign, slowly growing tumor of the pineal gland. The pineal gland is a small endocrine gland close to the center of the brain that secretes melatonin into the bloodstream. Pineocytomas can cause pressure and fluid build-up in the brain.

A pineal gland cyst is a usually benign (non-malignant) cyst in the pineal gland, a small endocrine gland in the brain. Historically, these fluid-filled bodies appeared on 1-4% of magnetic resonance imaging (MRI) brain scans, but were more frequently diagnosed at death, seen in 4-11% of autopsies. [ 1 ]

Treatment options for these tumors include chemotherapy, and bone marrow transplants. Osteosarcoma are tumors that mainly affect the joints, bones and lungs. Osteosarcoma can lead to swelling, loss in dexterity, coughing, and breathing difficulties. Diagnosis is done by radiographs usually followed by a biopsy.
I'd like to clarify that a cyst is not a tumor. It is my understanding that a cyst is fluid filled, whereas a tumor is a solid mass. As for the pineal gland cyst, most are asymptomatic - in other words, individuals lead normal lives with none of those symptoms described by in this article. Right now, there are no known causes of pineal gland cysts.
Papillary Tumors of the Pineal Region are located on the pineal gland which is located in the center of the brain. The pineal gland is located on roof of the diencephalon. It is a cone-shaped structure dorsal to the midbrain tectum. [3] The tumor appears to be derived from the specialized ependymal cells of the subcommissural organ.
The pineal gland is a small organ in the center of the brain that is responsible for controlling melatonin secretion. [2] Several tumors can occur in the area of the pineal gland, with the most aggressive being pineoblastoma. Pineoblastomas arise from embryonal cells in the pineal gland and are rapidly growing.
