title: Sentinel lymph node biopsy in patients with male breast carcinoma: report of two cases.
abstract: The incidence of male breast cancer is low, and treatment strategies similar to those used for female breast cancer patients are frequently used for male patients. However, the safety and utility of sentinel lymph node biopsies (SLNBs) for male breast cancer have not been proven. Among the five cases of male breast cancer who received surgery at our hospital, mastectomy with SLNB was performed in two of the cases. The first patient was 77 years old and the second was 74 years old, and both presented as outpatients with chief complaints of a mammary mass. Clinical diagnoses were T1N0 in both cases, and mastectomies with SLNB were performed. The sentinel lymph node was identified using the dye method. Postoperatively, the patients were hormone receptor-positive, and they are now being followed while continuing to take oral tamoxifen.
