What is the matter with black spots on the white of the eyes

If the patient has a black spot on the whites of his eyes, I first consider it to be a conjunctival nevus. A conjunctival nevus is a congenital benign tumor that can occur in various parts of the conjunctiva and is the most common conjunctival tumor. The initial stage is small, can not change for a long time, most of them grow with age, adolescence has a growing trend, conjunctival pigmented nevus can be composed of small melanocytes, giant cells, epithelial-like cells, brown black, black blue or brown red, plastid micro-bulge, clear boundary, smooth surface without blood vessels, often smaller transparent conjunctival cysts, in general, nevus good hair in the corneal limbus and palpebral fissure bulbar conjunctiva, rarely transformed into malignant. If the patient shows a sudden increase in mole body, indicating signs of malignant transformation, we should take symptomatic treatment according to the condition.
