Congenital Hypertrophy of the Retinal Pigment Epithelium (CHRPE) CHRPE is a flat, darkly pigmented spot found in the back of your eye. The PRPH2 gene encodes a photoreceptor-specific glycoprotein, which is essential for the morphogenesis of rod and cone photoreceptor outer segments. CHRPE prevalence has been reported to be increased in subjects with familial or sporadic non-polyposis colorectal cancer (CRC), suggesting that some individuals with non-polyposis CRC have an attenuated form of FAP. (a) Large, peripheral CHRPE with centrally located lacunae. Most (typical) CHRPE lesions carry no significance to the patient and, once diagnosed, no follow-up is generally necessary. The thickening appears on funduscopic examination as an oval, black, clearly demarcated lesion within which there are atrophic areas surrounded by a halo that has no pigment. In this case, the maculopathy responded to bevacizumab. CHPRE has been an association with Gardner's Syndrome (familial colonic polyposis).

Congenital hypertrophy of the retinal pigment epithelium, once considered to be a stationary lesion, has recently been documented to show an increase in basal dimensions. It seems to be correlated with the position of constitutional mutations adenomatous polyposis coli (APC) gene. It can be solitary or multifocal, the latter is congenital grouped pigmentation or "bear tracks." Since the multifocal variant is not important in the differential diagnosis of fundus tumors, it is not .
