| Concurrent with these changes is the formation of marginal osteophytes that are excrescences of bone arising at the margins of the joint. |
| Surface ulceration was also present focally in the tumor with the multifocal papillary excrescences. |
| On section, it was unilocular and lined by a dark pink-gray, friable material with yellow papillary excrescences. |
| Moreover, from early accounts, it is often difficult to distinguish true large bony outgrowths from scalp excrescences. |
| In Switzerland, particularly in the Vallais, the people are subject to excrescences on the throat similar to the Derbyshire neck. |
| All dendrites bear large numbers of spines, small excrescences on which incoming nerve fibres terminate to form synapses. |
