[A Case of Solid Papillary Carcinoma In Situ-A Case Report].

Solid papillary carcinoma(SPC)is a rare histological type of breast cancer, accounting for only 1% of all breast cancer. We report a patient with right breast SPC who underwent total mastectomy. An 88-year-old Japanese woman presented with bloody nipple discharge and a palpable right breast mass. Mammography revealed a well defined high-concentration mass. Core needle biopsy revealed a diagnosis of suspicious of SPC, ER(+)[>95%], PgR(+)[>95%], HER2(1+). A right mastectomy and sentinel lymph node biopsy were performed. The patient was diagnosed with pathological stage 0(Tis, N0M0)breast carcinoma, SPC in situ type with neuroendocrine markers. The patient has survived without any recurrence for 4 years.
