The patient, a 21-year-old pretty female university student, felt discomfort in her neck 7 months ago, and on closer inspection the left side of her neck was visibly swollen and a large soft mass was palpable, which obviously affected the aesthetics of her neck. She went to a local hospital and was diagnosed with a cystic lymphoma in the left lateral neck area, with a size of about 13*3.5*1.5 cm. She was told by the local doctor that traditional surgical excision would be more effective, but the permanent scar left on the neck would affect the aesthetics of the neck. Hearing this, she hesitated. So, the doctor decided to treat her with aspiration to see if it would relieve the symptoms and eliminate the swelling. After the aspiration treatment the lump shrank, but within 1 month the lump grew back. The doctor told her that pumping alone was not effective and that surgery might be necessary to solve the problem at its root. The surgical incision was very discreet and left no scar on the neck During the surgery, 0.5cm, 1.2cm and 0.5cm surgical incisions were made in the left axilla, 11 points on the left areola margin and 2 points on the right areola margin to place the Trocar and surgical instruments, respectively, and successful lumpectomy of the cystic lymphadenoma was completed under lumpectomy. The excised mass was packed into a specimen bag and removed through the 1.2-cm surgical incision. Due to the small size of the surgical incision itself and the very discreet location, she was very pleased with the cosmetic results of the procedure after healing. Lumpectomy for more patients with neck disease Cystic lymphadenoma of the neck (also known as lymphatic duct cyst and lymphatic hydrosalpinx) is a congenital benign disease with unsatisfactory results from current aspiration therapy and sclerotherapy. The efficacy of traditional open surgical excision is definite, but the permanent postoperative scars in the neck can cause a great psychological burden to some young patients with high cosmetic requirements. Lumpectomy has been applied to treat neck diseases for nearly 20 years and has brought real benefits to patients with goiter, hyperthyroidism and parathyroid disease. The lumpectomy technique is very popular among patients because it can provide excellent cosmetic results while solving the pain of the disease. It is worth pointing out that there are no reports of cystic lymphadenoma of the neck treated by lumpectomy in Japan or abroad. 1) The MRI findings are that the cysts are clearly layered and within resectable limits; 2) This is the center that has performed the earliest and most lumpectomies in China, and has rich experience in lumpectomies for neck diseases.
