Abstract
- Dermoid tumors of tbe corneal limbus are failYly common congenital lesions. They are noted -at birth and may grow slowly in size and encroach upon the pupillary area occupying a site partly over the cornea and partly over the sclera. The tumors are yellowish, elevated and variable in size. Histologically the tumor consists of fibrofatty tissue covered by epidermoid epithelium and are invaded by ectodermal derivatives such as hair follicle, sebaceous and sweat glands. Trauma, irritation and puberty may hasten their growth. About 30% of patients with. corneal dermoid exhibit other congenital anomalies of ocular tissue, face, teeth, jaw, ear, spine, skull, and so on. Recently two cases of limbal dermoids were seen in our clinic. Histologically hair follicles and sebaceous glands are shown in one specimen, and cartHage and sebaceous glands in the other specimen.
