Objective

The rare occurrence of haemangiosarcoma of the third eyelid in 2 Great Dane dogs which has never been previously reported especially in this breed of dog was presented.

Case History

Case 1

A dog was presented with a proliferative bright red mass, 0.4 x 0.8 x 0.4 cm. in size, on the palpebral aspect of the third eyelid. The mass had been developed for three months. Bleeding from the side of the mass was occasionally noticed. The mass was surgically removed. The recurrence of the mass at the same site had been observed in 4 months after the surgery. Amputation of the third eyelid was the second surgery. There was no occurrence within 12 months.

Case 2

A dark red mass was protruding out of the palpebral aspect of the third eyelid in a dog. The mass had been developed for six months. The surgical removal of the third eyelid was the treatment of choice. Evaluation of the patient at 12 months after the surgery was satisfactory.

Discussion

Haemangioma more commonly involves the bulba conjunctiva than the third eyelid. Tumor of the third eyelid in the dog tends to occur most commonly at the leading margin and less commonly at the limbus. Amputation of the third eyelid is the treatment of choice.

Conclusion

Surgical removal of the haemangiosarcoma of the third eyelid could not prevent the recurrence of the mass. Amputation of the third eyelid was the only successful surgical treatment in 2 Great Dane dogs when early detection and diagnosis were made.
