Eye malignant neoplasms are rarely diagnosed types of neoplasms. If, however, they are diagnosed, they not only carry a risk of loss of sight or eyeball, but also of life, especially as they can metastasize to other organs, such as the brain. Find out how to recognize the symptoms of malignant eye tumors.
Malignant neoplasms of the eyeare diagnosed very rarely. However, if they do occur, they can reach every part of the eye: optic nerve, retina, iris, lacrimal gland, eyelid and skin around the eyes, often directly threatening the patient's life.
Malignant neoplasms of the optic nerve
Two types of very rarely diagnosed malignant tumors can develop within the optic nerve:glioblastomaandmeningioma . These types of changes growing within the eye can attack the optic nerve and, consequently, impair visual acuity and eye mobility. Both tumors are characterized by gradual loss of vision and optic nerve atrophy. Later, when the tumor grows larger, it becomes exophthalmic. It is worth knowing that optic nerve glioma accounts for 20 percent. orbital tumors in children. In turn,meningioma of the sheaths of the optic nervemost often affects middle-aged women.
Malignant neoplasms of the eyelids
The most common malignant neoplasm of the skin of the eyelids is cancer, which occurs in the elderly. In 93 percent. cases it is a life-threatening form of cancer - basal cell carcinoma, which does not metastasize at all. How to recognize eyelid cancer? In the initial stage of development, a flat, painless lump appears on the skin, which does not differ in appearance from he althy skin. As the disease progresses, the tumor grows in size, and a crust forms in the central part, bleeding when attempted to remove it.
Malignant neoplasms of the orbit
Sarcoma , a neoplasm originating from mesenchymal tissue (embryonic connective tissue), is the third most common malignant neoplasm in children after neuroblastomy and Wilms' tumor. It comes in four forms: embryonic, vesicular, multiform and acinar. This type of cancer usually appears in the first decade of life and presents with exophthalmos, which is often diagnosed as inflammation.Important
Beware of malignant melanoma
Czerniakmalignantis the most commonly diagnosed malignant neoplasm of the eye. Moreover, this cancer accounts for up to 20 percent of all melanomas. It is very dangerous because it usually does not give any symptoms for a long time and is usually diagnosed during an accidental visit to an ophthalmologist. Melanoma is characterized by the formation of a light to dark brown lump (more visible in the blue iris) that grows slowly, sometimes causing distortion of the pupil.
Retinoblastoma is the most common intraocular malignant neoplasm of the eye in children. It stems from immature cells in the retina, which become malignant and grow abnormally in the eye, destroying the rest of the eyeball. The characteristic fears of a retinal tumor are leukocoria (white pupillary reflex) and strabismus.
Tumor of the lacrimal gland
The most common cause of orbital tumors in adults is metastasis, which usually appears in middle age or elderly age, more often in men. Tumor of the lacrimal gland manifests itself as exophthalmia, double vision (due to the involvement of the oculomotor muscles by the tumor) and reduced visual acuity (due to damage to the optic nerve).
