Abstract
Key Clinical Message
Describes a rare form of invasive breast cancer of no special type.Not a distinct morphological subtype.Characterized by dense lymphoid infiltrate, syncytial growth, pushing borders, and cells with high-grade nuclei.Clinically aggressive but carries a better prognosis than other more frequent invasive breast carcinomas.
Abstract
Invasive breast carcinoma of no special type with medullary pattern (BCNST-MP) is a rare form of breast tumor, accounting for less than 5% of all invasive breast carcinomas. Its diagnosis is based on histologic criteria. Historically, this tumor was known as medullary carcinoma. Poor morphological reproducibility led to re-classification. Despite having an aggressive biological behavior, these tumors usually carry a better prognosis compared with other more frequent forms of invasive breast carcinomas. Herein, we present a case of BCNST-MP in a 58-year-old African female, successfully treated in our institution through chemo-radiation, hormonal therapy and surgery.
