Major lymph nodes of the head of the fallow deer (Dama dama) and lymphatic drainage of antlers.

Heads from 10 fallow deer bucks were examined to provide a description of the major lymph nodes in this region. The distribution and size of these nodes were similar to those of sheep and goats. To determine whether there was drainage of lymph from the skin of antlers, and to follow the route of this drainage, a solution containing Evans blue was injected intradermally into the antlers of 2 bucks whilst the animals were anaesthetised. Dye appeared in tracheal lymph ducts 14 to 30 min after injection. The spread of blue colouration in lymphatic ducts and nodes, seen at post-mortem examination, indicated that lymph flowed from antlers laterally into the ipsilateral parotid lymph nodes and from these via medial and lateral retropharyngeal lymph nodes to the tracheal ducts.
