Endoscopic ultrasound-guided paracentesis can diagnose invasive lobular breast carcinoma presenting atypically with gastrointestinal symptoms. This technique aids in identifying metastatic cancer when breast findings are absent, also highlighting Lynch syndrome.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Metastatic breast cancer can present with nonspecific gastrointestinal symptoms.
- Invasive lobular breast carcinoma (ILC) may lack typical clinical or radiographic breast findings.
- Lynch syndrome is associated with an increased risk of various extraintestinal malignancies.
