Metastatic jejunal neuroendocrine tumor to the breast: Case report and literature review
Abstract Neuroendocrine tumors (NETs) are the most prevalent neoplasm of the small bowel; these present a diagnostic challenge because of their low prevalence and non-specific clinical manifestations. Breast metastasis is rare. We present the case of a 55-year-old female with a painful nodule in the right breast. Mammography reported a solid mass, BBIRADS 4C, with no axillary lymph nodes. Biopsy reported infiltrating ductal carcinoma. Conservative surgery was performed. Histopathology findings are compatible with a well-differentiated (G2) metastatic NET with a gastrointestinal primary. Ga. DOTANOC positron emission tomography/computed tomography scan showed proximal jejunum diffuse mucosal thickening with two foci of increased radiotracer uptake with adjacent adenopathies.
