Contrary to general expectations it was successfully removed by Portalupi, a surgeon of Venice.

It weighed 57 pounds, being 20 1/2 inches long and 30 inches in circumference.

It is said this tumor followed the reception of a wound.
Among the benign bone tumors are exostoses--homologous outgrowths differing from hypertrophies, as they only involve a limited part of the circumference.

When developmental, originating in childhood, the outgrowths may be found on any part of the skeleton, and upon many and generally symmetric parts at the same time, as is shown in Figure 248.
Barwell had a case of a girl with 38 exostoses.

Erichsen mentions a young man of twenty-one with 15 groups of symmetric exostoses in various portions of the body; they were spongy or cancellous in nature.
Hartmann shows two cases of multiple exostoses, both in males, and universally distributed over the body.
Macland of the French navy describes an affection of the bones of the face known as anakhre or goundron (gros-nez).
