We describe the clinicopathological and morphological features of an unusual breast carcinoma classifiable as a lipid-rich variant of ductal invasive carcinoma, with a basal-type immunohistochemical profile. Basal-type breast cancers show no hormonal receptor expression, rarely over-express HER-2 but exhibit molecular high weight cytokeratins, EGFR and c-kit positivity. Special stains and histochemistry tests were used to elucidate the nature of vescicles in the neoplastic cells. Sudan IV was performed on formalin-fixed tissue. Commercially available antibodies tested were: ER, PgR, EGFR, HER2, c-kit, high molecular weight cytokeratins. Cytoplasmic lipids were highlighted as red-orange droplets on Sudan IV staining. As for immunohistochemistry, the tumor showed no reactivity to ER, PgR and HER2 (triple negative), and diffuse and strong positivity to high weight cytokeratins, EGFR and c-kit, such as a basal-type breast carcinoma. A basaloid phenotype in a lipid-rich carcinoma has not been previously reported.

Importance: Enhanced breast cancer screening with magnetic resonance imaging (MRI) is recommended to women with elevated risk of breast cancer, yet uptake of screening remains unclear after genetic testing.
Objective: To evaluate uptake of MRI after genetic results disclosure and counseling.
Design, Setting, And Participants: This multicenter cohort study was conducted at the University of Southern California Norris Cancer Hospital, the Los Angeles General Medical Center, and the Stanford University Cancer Institute.

Background: Transcutaneous electrical stimulation after breast cancer surgery has been utilized for various purposes, but the full efficacy of this treatment approach on postoperative symptoms remains unclear.
Aim: This study aimed to answer the question: Does transcutaneous electrical nerve stimulation significantly impact postoperative patient outcomes in individuals undergoing breast cancer surgery?
Methods: A systematic review of randomized controlled trials was conducted. Because of the limited number of studies included, it was not feasible to perform a meta-analysis.

Esophageal squamous cell carcinoma (ESCC), the most predominant subtype of esophageal cancer, is notorious for its high lymph node metastatic potential and poor prognosis. Growing evidence has demonstrated crucial function of circRNAs in human malignancies. However, the knowledge of circRNAs in lymph node metastasis of ESCC is still inadequate.

Objectives: To predict and characterize the three-dimensional (3D) structure of protein arginine methyltransferase 2 (PRMT2) using homology modeling, besides, the identification of potent inhibitors for enhanced comprehension of the biological function of this protein arginine methyltransferase (PRMT) family protein in carcinogenesis.
Materials And Methods: An method was employed to predict and characterize the three-dimensional structure. The bulk of PRMTs in the PDB shares just a structurally conserved catalytic core domain.

Background: Colorectal metastasis from primary breast cancer is rare and presents a challenge for diagnosis and treatment.
Aim: To report two cases of colorectal metastasis from a primary invasive lobular breast carcinoma (ILBC) with different presentations while discussing the mode of diagnosis, immunohistochemistry (IHC), course of treatment, and response.
Case 1: A 47-year-old female, with a known case of bilateral invasive lobular breast cancer, was diagnosed in 2015 and staged as p Tx N3 M0.
