title: [A case of multiple breast mucinous carcinomas].
abstract: A case was a 46-year-old woman who presented with the left breast lump confirmed about 30 years ago. In August 2006, the patient came to our hospital for consultation due to her breast lump was enlarged. Mammography revealed a frequent occurrence of the mass shadow of marginal irregularity and we diagnosed it with category 4. Breast echography showed a lot of irregular lesions. Even breast MRI presented a multiple mass-related lesion. The malignancy was possible, and a needle biopsy diagnosed them to be mucinous carcinoma. Pectoralis muscle preservation mastectomy and sentinel lymph node biopsy technique were used for surgery. Histopathology also diagnosed it to be mucinous carcinoma, T2N0 M0, stage IIA, ER (+), PgR (+), HER2 score 0. It has been 4 years since the operation but no sign of recurrence/metastasis was observed at present. There have been few reports of breast cancer with multiple cases, mucinous carcinoma as a case in point. Therefore, we report the invaluable case in addition to some paper consideration with it.
