The present study describes giant-cell tumor of bone (GCToB) with lymph node involvement in a 5-year-old crossbred cat. The animal was referred to the surgery clinic with progressive subcutaneous swelling in the left proximal femoral region, severe lameness, constipation, and dysuria. A moderately firm, subcutaneous, palpable mass, 9 cm in diameter, was observed, and biopsy samples were taken.
