Pain is inconstant but is the first symptom to occur in most of the cases; it occurs spontaneously, is usually localized. Its severity increases slowly with periods of remission, and analgesics do not succeed in stopping it completely. The value of the tumor as an objective symptom depends on its superficial location; its size varies from that of a hazelnut to that of an orange; it may also be fusiform; its surface is smooth and regular, and the soft tissues do not adhere to it.
