Giant Phyllodes Tumor in Ectopic Breast Tissue.

Published: June 2020

Breast masses are uncommon in children and adolescents. Ectopic breast tissue is further uncommon and may be present in locations such as the face, back, and thigh. A 12-year-old female child presented with a hard, nonmobile lump in the right breast. On exploration by submammary incision, the lump was found to be below the pectoralis major muscle and had no communication with the overlying orthotopic breast tissue. Histopathological examination revealed a well-encapsulated biphasic lesion, with features characteristic of a phyllodes tumor. We report a hitherto unreported case of aberrant breast tissue lying under the pectoralis muscle and containing phyllodes tumor.

Purpose: Parastomal hernia is a frequent complication after stoma construction, with increasing incidence over time. Surgical repair is reported with a high recurrence rate and the evidence on the topic is limited. We conducted a retrospective study to evaluate the incidence of recurrence after parastomal hernia repair and assessed the risk factors and predictors for recurrence at the Regional Hernia Center at Horsens Regional Hospital, Denmark.

Addressing the consequences of exposure to endocrine-disrupting chemicals (EDCs) demands thorough research and elucidation of the mechanism by which EDCs negatively impact women and lead to breast cancer (BC). Endocrine disruptors can affect major pathways through various means, including histone modifications, the erroneous expression of microRNA (miRNA), DNA methylation, and epigenetic modifications. However, it is still uncertain if the epigenetic modifications triggered by EDCs can help predict negative outcomes.

Spatially resolved transcriptomics technologies potentially provide the extra spatial position information and tissue image to better infer spatial cell-cell interactions (CCIs) in processes such as tissue homeostasis, development, and disease progression. However, methods for effectively integrating spatial multimodal data to infer CCIs are still lacking. Here, the authors propose a deep learning method for integrating features through co-convolution, called SpaGraphCCI, to effectively integrate data from different modalities of SRT by projecting gene expression and image feature into a low-dimensional space.

Introduction: Triple-negative breast cancer (TNBC) is the most challenging subtype of breast cancer to treat. While previous studies have demonstrated that ginsenoside Rh2 induces apoptosis in TNBC cells, the specific molecular targets and underlying mechanisms remain poorly understood. This study aims to uncover the molecular mechanisms through which ginsenoside Rh2 regulates apoptosis and proliferation in TNBC, offering new insights into its therapeutic potential.
