Malignant Phyllodes Tumor With Chondroblastic Osteosarcomatous Differentiation: A Case Report.

Malignant phyllodes tumors (MPTs) represent the most pernicious type of intralobular stromal proliferation known as a "fibroepithelial lesion" (FEL). They comprise a small fraction of breast malignancies and can present as either a pure MPT or sometimes include a heterologous component (liposarcoma, chondrosarcoma, osteosarcoma, or rhabdomyosarcoma). Of the fraction of MPTs that include heterologous components, very little about those with chondroblastic osteosarcomatous differentiation has been described in the literature.

A case of bilateral male breast cancer- What does it teach us?

Male breast cancer is rare, with a lifetime risk of 1 in 833 males, with bilateral male breast cancer being extremely uncommon. This report describes a rare case of bilateral breast cancer in a 74-year-old male who presented with a breast lump and incidental calcifications in the contralateral breast. This case highlights the similarities, as well as differences, in presentation and imaging features of breast cancer in males and females.

Can COVID-19 worsen racial disparities in breast cancer screening and diagnosis?

Background: Health disparities among minority groups, especially African Americans, can limit their access to quality medical care and lead to disproportionate medical management and disease outcomes. The aim of this study was to compare the COVID-19-related change in mammogram volumes and cancer detection at two affiliated academic breast centers, one that serves a predominantly African American patient population and one that serves a predominantly non-African American patient population.

Materials And Methods: For the purpose of anonymity, racial demographics were collected and the center with a higher African American patient population was designated as institution A, while the center with a higher non-African American patient population was designated as institution B.
