Adenoma of the limbal conjunctiva.

On February 16, 1950, a woman aged 36 came to the ophthalmological clinic with a small tumour on the right eyeball. She remembered having observed it for the first time at the age of 10 years, and it had recently started growing slowly (Fig. 1). Examination.-The eye presented a yellowish, well-defined, rather thin tumour, measuring 5 x 3.5 mm., situated on the limbal conjunctiva between 3.30 and 5 o'clock. It did not adhere to the deep layers and had a rich vascularization, best noticeable on the surface, which was irregular and embossed, especially near the corneal margin. Slit-lamp examination distinctly revealed three cyst-like formations in the lower parts of the neoformation. Three large blood vessels, issuing from the semilunar plica and the inner part of the conjunctiva, converged to the tumour, where they branched out.
