Surgery:
Excision of a GCTB is the standard treatment whether benign or malignant
and it is often curative. Due to the infiltrative growth pattern of this
tumor, wide surgical margins are needed and have been shown to diminish
the recurrence risk [11,51]. Local excision of lymph nodes or
sentinel lymph node biopsy is not indicated except in the cases of
malignant GCTB [11,12,52].
