Breast cancer combined with contralateral neck lymph node metastasis: a case report

Area of Science:

• Oncology
• Breast Cancer Research
• Metastasis Studies

Background:

• Contralateral neck lymph node metastasis is an uncommon occurrence in primary breast cancer.
• Current clinical staging and treatment guidelines for this condition are not well-established.
• This rarity poses diagnostic and therapeutic challenges in oncology.

Observation:

• A 30-year-old female presented with a right breast mass and ipsilateral neck lymphadenopathy.
• Mammography and ultrasound revealed a significant breast mass and suspicious cervical lymph nodes.
• Intraoperative pathology confirmed breast malignancy and metastatic poorly differentiated carcinoma in the cervical lymph nodes.

Findings:

• The patient underwent a right mastectomy following intraoperative diagnosis.
• A multidisciplinary treatment plan including chemotherapy, targeted therapy, radiotherapy, and endocrine therapy was initiated.
• The long-term outcomes of this aggressive treatment approach are yet to be determined.

Implications:

• This case underscores the complexity of managing rare metastatic patterns in breast cancer.
• It emphasizes the need for tailored treatment strategies when standard protocols are insufficient.
• Further research is warranted to improve understanding and management of contralateral neck lymph node metastasis in breast cancer patients.
