Hematogenous pigmentation, following hemorrhage into a sarcomatous growth, may be differentiated from melanotic pigmentation by its lighter colour, being golden or brown, never black, and by giving an iron reaction.

Fig. 103.—An epibulbar, melanotic, sarcoma of the conjunctiva, 5, starting at the limbus. contain pigment granules. In the dark races the amount of pigment is such as to produce a brown ring around the cornea. As epibulbar sarcomata are generally pigmented, the pigment in them being melanin and not hematogenous, it is probable that many of them originate in these cells. Though the limbus is the commonest site for a sarcoma of the conjunctiva, it may occasionally begin in other parts, and has been seen to start from the plica Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Collins, E.
