Benign tumors are usually well-differentiated and well-demarcated, with low mitotic activity, no metastases, and no necrosis.
Malignant tumors (cancers) may show poor differentiation, erratic growth, local invasion, metastasis, and apoptosis. High mitotic activity.
Fat tumors:
- Lipoma: benign, low mitotic activity
- Liposarcoma: malignant, increased mitotic activity

Because of histology and gross appearance... very graphic description of fat cell tumor there

because the question said irregular vacuolated cells, describing fat cells. Rhabdomyosarcoma comes from skeletal muscle.

Lipomas/Liposarcomas are the commonest soft-tissue tumors in adults. The high mitotic index & infiltrative nature indicate that the mass is malignant.
