Background: Gastrointestinal metastasis from primary breast carcinoma is uncommon, anorectal involvement is extremely rare.

Case Presentation: We present the case of a 65-year old woman who underwent treatment for an infiltrative lobular carcinoma of the left breast with bone metastases and who developed metastasis of the rectum and anal canal 4 years later.

Conclusions: A patient with a history of breast cancer, especially lobular carcinoma, presenting with anorectal symptoms, should raise the suspicion of metastatic disease.

Background: Breast carcinoma stands out as the most widespread invasive cancer and the top contributor to cancer-related mortality in women. Nanoparticles have emerged as promising tools in cancer detection, diagnosis, and prevention. In this study, the antitumor and apoptotic capability of silver nanoparticles synthesized through Scrophularia striata extract (AgNPs-SSE) was investigated toward breast cancer cells.

SHP2 promotes the epithelial-mesenchymal transition in triple negative breast cancer cells by regulating β-catenin.

Purpose: Growing evidence suggests that the tyrosine phosphatase SHP2 is pivotal for tumor progression. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer, characterized by its high recurrence rate, aggressive metastasis, and resistance to chemotherapy. Understanding the mechanisms of tumorigenesis and the underlying molecular pathways in TNBC could aid in identifying new therapeutic targets.

Background: Male breast cancer (MBC) is rare and often treated using evidence from female breast cancer (BC) trials due to limited male participation. Previous estimates lacked global coverage and completeness. We aimed to quantify the global MBC burden from 1990 to 2021 and evaluate its current status and trends.

Mucinous carcinoma of the breast, also known as colloid carcinoma, is an uncommon type of differentiated adenocarcinoma, representing only 2% of all invasive breast carcinomas. It usually occurs in women ≥ 60 years of age. Mucinous carcinoma is characterized by clusters of epithelial tumour cells suspended in pools of extracellular mucin and is further divided in 2 subgroups, pure and mixed.

Recurrence beyond the second year of diagnosis and metastasis to the skin and eyelids are rare occurrences in breast cancer. When cutaneous metastases present without local recurrence, they pose a significant diagnostic challenge. Here, we describe a case of breast cancer that recurred 16 years after the initial treatment, with the only indication of recurrence being unusual skin and eyelid lesions.
