Trilateral retinoblastoma
Trilateral Retinoblastoma
Trilateral retinoblastoma (/traɪˈlætərəl ˌrɛtɪnoʊblæˈstoʊmə/) is a rare form of retinoblastoma, a type of cancer that begins in the retina, the sensitive lining on the inside of the eye.
Etymology
The term "trilateral" comes from the Latin "tri-" meaning "three" and "lateral" meaning "side". "Retinoblastoma" is derived from "retino-", referring to the retina, and "-blastoma", a suffix used in pathological terms to denote a cancer comprising immature cells.
Definition
Trilateral retinoblastoma is characterized by the presence of bilateral retinoblastoma (cancer in both eyes) along with an intracranial neuroblastic tumor, typically in the pineal gland or less commonly, the suprasellar or parasellar region. This third tumor gives the condition its name.
