Can childhood lymphatic malformations of the thigh be cured? Will they recur?

Patient's question:

1 year 8 months girl, in the past 2 months, a lump was found on the left thigh, skin color is normal

Doctor's answer:

Pingyangmycin can be used to treat lymphangiomatosis. Overall, the effective rate is around 60%. It is not very effective for polycystic tumors and requires multiple injections. Surgical treatment is relatively more effective, but about 10% of cases may experience tumor recurrence. For small recurrent tumors, observation can continue, while large recurrent tumors can only be treated with reoperation.
