Patient: The patient is male, 61 years old, and has a tumor on the back of his head, about 20 centimeters, and sometimes pus comes out. He went to the 10th People’s Doctor, but the doctor said that the tumor was too large, and after opening it, he needed a skin graft, which the hospital could not do, so he did not open it. Doctor: There are many different types of lumps in the head, depending on the location, size and nature of the origin of the lump, so the treatment plan varies. However, the size of the lump in your posterior occipital region alone is very large for a 20 cm head lump, and it has an ulcer, so it is likely that tissue repair (skin graft or flap graft) will be required after surgical removal of the lump. In addition, it is advisable to have a CT or MRI of the head to clarify the extent of the mass, whether the skull is involved, whether there is intracranial involvement, and the possible pathology before the doctor can make a reasonable judgment and treatment plan.
