A Case Report of a Rare ER+, PR- Pure Metaplastic Breast Squamous Cell Carcinoma with HER2 Overexpression.

BACKGROUND Breast squamous cell carcinoma (SCC) is a subtype of metaplastic breast carcinoma (MBC), which is a rare malignancy and accounts for 0.1% of all invasive breast carcinomas. Guidelines on definitive management and treatment of breast SCC are not well established, given its rarity and diverse immunohistochemistry (IHC) profile, and lack of clinical data.

Long term outcome of immunoglobulin A (IgA) nephropathy: A single center experience.

Introduction: IgA nephropathy (IgAN) has a heterogeneous presentation and the progression to end stage renal disease (ESRD) is often influenced by demographics, ethnicity, as well as choice of treatment regimen. In this study, we investigated the long term survival of IgAN patients in our center and the factors affecting it.

Methods: This study included all biopsy-proven IgAN patients with ≥ 1year follow-up.

Absolute cosine-based SVM-RFE feature selection method for prostate histopathological grading.

Objective: Feature selection (FS) methods are widely used in grading and diagnosing prostate histopathological images. In this context, FS is based on the texture features obtained from the lumen, nuclei, cytoplasm and stroma, all of which are important tissue components. However, it is difficult to represent the high-dimensional textures of these tissue components.
