Does a positive intramammary lymph node mandate a complete axillary node dissection? Context: We hypothesized that even in the face of a positive intramammary lymph node (IMLN) a negative axillary sentinel lymph node (SLN) reliably stages the axilla and complete axillary lymph node dissection (CALND) can be avoided. A literature search identified 386 publications that included IMLNs and SLN biopsies. Patients with a positive IMLN and negative axillary SLN who underwent a CALND were included. A review of our database was also performed. Twenty-one cases in the literature met our criteria. A review of our database resulted in 2 additional cases. Twenty-three patients were identified who had a positive IMLN, negative axillary SLN biopsy, and underwent a CALND. In all cases, the CALND was negative.

An axillary SLN biopsy accurately represents the disease status of the axilla in cases with a positive IMLN. CALND can be avoided in the setting of a positive IMLN and a negative axillary SLN biopsy. Final Decision: no
