Retinoblastoma

Retinoblastoma (Rb) is a rare form of cancer that rapidly develops from the immature cells of a retina, the light-detecting tissue of the eye. It is the most common primary malignant intraocular cancer in children, and it is almost exclusively found in young children. Though most children survive this cancer, they may lose their vision in the affected eye(s) or need to have the eye removed Retinoblastom er en ondartet svulst i netthinnen hos barn. Retinoblastom er den vanligste øyesvulsten hos barn. Det er omtrent fire nye tilfeller per år i Norge. 90 prosent av svulstene påvises før fem-årsalderen. Retinoblastoma can also spread (metastasize) to other areas of the body, including the brain and spine. In the majority of cases, it's not clear what causes the genetic mutations that lead to retinoblastoma. However, it's possible for children to inherit a genetic mutation from their parents How does retinoblastoma develop? The eyes start to develop well before birth. During the early stages of development, the eyes have cells called retinoblasts, which multiply to make new cells that fill the retina.At a certain point, these cells stop multiplying and become mature retinal cells Retinoblastoma is usually diagnosed before a child reaches the age of 3. Retinoblastoma can be hereditary (passed down in families) or non-hereditary. Forty percent of retinoblastoma patients have a genetic defect that leads to multiple tumors in one eye or both eyes. This is known as hereditary or germline retinoblastoma

Retinoblastoma is the most common primary intraocular malignancy of childhood. It typically presents with leukocoria or strabismus. In later stages of the disease, the child may exhibit proptosis, buphthalmos, or hypopyon. The pathognomonic molecular aberration is a loss of function mutation in the Retinoblastoma classically presents with one or multiple nodular, white or cream colored masses often associated with increased vascularization. There are two primary clinical patterns of retinoblastoma growth. If the tumor grows anteriorly into the vitreous it is known as an endophytic tumor The retinoblastoma protein (protein name abbreviated Rb; gene name abbreviated RB or RB1) is a tumor suppressor protein that is dysfunctional in several major cancers. One function of Rb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, Rb is phosphorylated to pRb, leading to the inactivation of Rb Retinoblastoma, extraocular stage (neglected with necrosis). History: RC, 2-year-old male with chief complaint of left orbital mass. Born full-term spontaneous vaginal delivery (FTSVD) to a gravida 3, para 2 (2001) at home. Three months prior to admission (PTA), an inward deviation of the left eye was noted Retinoblastoma is a rare cancer that can rob young children of their sight.
