Cystic hygromas (cystic lymphangiomas, macro cystic lymphatic malformations) are seldom observed in different animal species and they have not yet been reported in goats. They are rare benign congenital vascular disorders of the lymphatic system that commonly localize in the cervico-facial region. A two-month-old, male crossbred goat-kid presented with a single swollen and painless mass (5 cm in diameter) on the left side of the mandible area occurring from birth. Ultrasonography showed a fluid-filled multi-lobular cystic lesion with internal separations. The cytological examination revealed the presence of cloudy serous fluid with a predominance of lymphocytes. To the authors’ knowledge, this is the first description of a congenital lymphatic anomaly in goats.
