Fractionated beta-radiation was applied on a conjunctival lymphangioma, which had been known for several years. Histological diagnosis was established 3 years previously. Excision was not possible because the tumor had involved a considerable part of the conjunctiva. Using a strontium-90 applicator a total dose of 30 Gy was applied in 6 fractions with 5 Gy each. The initial tolerance was satisfactory. No radiogenic damage occurred, an involution of the tumor could be observed. During a follow-up time of nearly 2 years no further progression was noted. We consider the beta-radiation as an interesting therapeutic alternative for conjunctival lymphangiomas which are difficult to treat surgically due to their size.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
