Secretory breast carcinoma in a 6-year-old girl: mastectomy with sentinel lymph node dissection.

Secretory breast carcinoma (SBC) is a rare type of breast neoplasia that was originally described in children. SBC is an indolent breast tumor with good clinical outcome and rare systemic involvement. Since, majority of studies concerning pediatric SBC have been case reports, it has been difficult to clearly elucidate the characteristics and optimal treatment strategies for SBC in children. Although treatment recommendations vary, surgical excision is the primary mode of treatment. Also, necessity of axillary and/or sentinel lymph node dissection is another matter of discussion in children. We report a 6-year-old girl who was diagnosed as SBC was reported to discuss the use of mastectomy with sentinel lymph node dissection in the treatment of this rare tumor in children.
