Metaplastic carcinoma of the breast

Abstract

Introduction: Metaplastic carcinoma is a rare tumor of low incidence that constitutes 0,2-1% of infiltrating carcinomas of the breast. It is characterized by presenting atypical differentiation of squamous, spindle cell or mesenchymal / matrix producing differentiation and it is associated with a poor prognosis.
Objective: to present a case with metaplastic carcinoma of the breast diagnosed by the PathologyDepartment.
Case report: 69-year-old female patient, white skin color, who comes due to presenting a rapidly growing increase in the size of the right breast accompanied by stabbing pain. Therefore, it is clinically interpreted as inflammatory carcinoma of the breast. Surgical treatment consisting of mastectomy was applied and a histological diagnosis of the mixed variant metaplastic carcinoma was made.
Conclusions: metaplastic carcinoma of the breast is a tumor of very low incidence characterized by heterogeneous atypical differentiation with surgical treatment of choice. The biopsy associated with immunohistochemistry constitutes the mainstay of diagnosis.
