ABSTRACT

Metaplastic breast carcinoma accounts less than 1% of breast malignincies and frequently seen with poorly diff erentiated ductal carcinoma of the breast. In this paper, the clinical fi ndings of a 16 years old female patient with metaplastic breast cancer and the treatment given has been presented.

Progressively enlarging mass lesion of left breast was evaluated with ultrasonography. The lesion was 6x7 cm in size with regular borders, heterogenous and hypoechoic structure. Before referral to our hospital, the lesion had been excised at another institution and histopathological diagnosis reported was myxoid liposarcoma. But, the histopathologic diagnosis changed to metaplastic breast carcinoma with the help of immunohistochemistry at our pathology department. The patient was operated with modifi ed radical mastectomy and myocutaneous latissimus dorsi fl ap was used for immediate breast reconstruction. There was two more foci of the tumor with the similar histopathological morphology. Estrogen receptor and C erbB-2 were negative and progesteron receptor was positive. There was no metastasis to axillary lymph nodes. She was given combination chemotheraphy (cysplatine, doxorubicine and cyclophosphamide) and radiotheraphy and under follow-up without any recurrence for eight months.
