Patient's question:
I heard that the baby in the neighbor's house got sick, so I went to visit him after work. I saw some small hard lumps on his calf, and touching them was very painful. He also had symptoms like fever, nausea, and vomiting. The neighbor took the baby to the hospital for a detailed examination, and the doctor said he had childhood soft tissue sarcoma.Doctor's answer:
Soft tissue sarcomas originate from fat, fascia, muscle, fibrous tissue, lymphoid tissue, and blood vessels. Each type of tissue has distinct histological, biological characteristics, as well as different local invasion, hematogenous, and lymphatic metastatic potentials. For tumors that are completely resectable, they must be excised along with the surrounding normal tissue (including the biopsy site, skin, and adjacent muscles). For tumors located in muscles, the affected muscle should be completely removed from both the head and tail. Lymph node dissection is performed only when clinical evidence indicates involvement of the lymph nodes.
