Treatment.—If epiphora exists and the condition does not subsideby treatment of the trachoma, the sac may be opened, the mucous mem-brane curetted, or the sac extirpated. Sarcoma of Lachrymal Sac.—This has been observed rarely. Sylvestii^reports a case in which the tumor sprang from the wall of the sac. Extir-pation was followed by recurrence in the orbit and parotid region. Epithehoma of Lachrymal Sac.—This is usually secondary to epitheliomaof the adjacent skin. Soc. franc, dopht., 189

They are elevated masses seldom affecting thepalpebral conjunctiva, and, as a rule, are pale in color, but may be pig-mented; they are supplied with a number of hairs, glands, etc., andmay be cystic, and present the characteristics of the skin. Fig. 133. Dermoid tuftior of the conjunctiva. Lipomata {Fatty Tumors).—^They are small in size, and are seen are apparendy situated beneath the conjunctiva; the epitheliumis thickened over them. Angioma, Angiocavernoma, and Telangiectatic Growths.—Theseare not very infre(|uent. They are seldom confined to the description and treatment, see I^ids, page 177. Bone.—Bone is occasionally found beneath the conjunctiva, andsituated between the outer margin of the cornea and the commissure. 212 THE CONJUNCTIVA Moles or Pigmented Patches.—These occur most frequently iniudividnals who ])reseiit similar spots on the skin. Fibrous Growths.—Fibrous growths, often containing some lipomatoustissue, occur rarely in the upper outer portion of the ocular are crescentic in form, with the concave border toward the cornea;sometimes they are brought into view only when the eye is rotateddownward and inward.
