She was found to have a benign lesion which continually relapsed, necessitating repeated excisions, ultimately leading to the diagnosis of LGASC after the third excision. Guidelines for the treatment of LGASC emphasize complete tumor excision, with adjuvant therapies only considered in cases with positive lymph node metastasis.
