Choroidepithelioma

Chorioidepitheloma (ChE, chorioidepitheloma) is a rare disease of the ocular orbit and eyeball, which is characterized by malignant degeneration of pigment cells of the choroid and the continuation of its growth in the orbital tissue. CE is a mesenchymal tumor with pronounced

Choroidal epithelioma is a rare brain tumor that arises from the epithelial cells of the choroid of the eyeball. This is a rare disease that can cause serious consequences, including vision loss and death. In this article we will look at choroidal epithelioma, its symptoms, causes, methods of diagnosis and treatment.

What is Choriodalapiteloma Choriodalapieloma (HEP) is a very rare undifferentiated malignant neoplasm of the eye. It originates from the vessels of the conjunctiva in the orbital region, which collect blood from the small vessels of the fundus and the upper part of the orbit. PLE usually occurs in males over 50 years of age. The etiology of PLE is unknown; it accounts for 1-2% of all optic nerve tumors. The disease was first described more than fifty years ago. the description has since been studied microscopically and classified as lymphoplasma cell histiotroblastoma. Other possible methods of description are lymphomas or tumors of vascular origin. Epidermoid choroidoma or choroidal epithelioma is a very rare tumor located in the ethmoid labyrinth. This type of tumor is one of the least studied tumors of the third eyelid, and therefore there has been no generally accepted term to classify or designate it. The classification of tumor diseases of the third century in the literature is extremely complex, and the number of proposed classifications for such neoplasms is growing exponentially: more than 40 different names have been registered in just 30 years. Among them are malignant epitheliomas, lymphomas, hemorrhages, fibrosarcomas, angioreticular sarcomas, etc. It is not surprising that most of these classifications, due to the lack of generally accepted diagnostic methods, are not widely used. Let's give one of them to demonstrate this confusion. Three main classifications of all neoplasms observed in the ethmoidal zone have been proposed: Classification of surgical complications after operations to remove emphysema of the paranasal sinuses. The lateral part of the lacrimal bone is not removed in all patients, but only in those who exhibit pathological changes in the mucous membrane of the ethmoid cells. In all other cases, the middle part of the horizontal plate is removed. According to Professor L.K. Bogush (1904), perhaps it is necessary to distinguish between inflammatory and non-inflammatory changes. Consequently, the ethmoid bone and bone walls are affected, then it is necessary to perform an intervention in the lateral wall from localization

**Chorioid papillomas (chorioplastic epitheliomas, dermoid formations of the choroid)** is a yellowish tumor-like formation, most often located in the suprachoroidal and extrabulbar space, but any part of the vascular tract can be involved. Forms more often in the second
