Benign metastasizing leiomyoma is a very uncommon clinicopathologic entity with unknown molecular pathogenesis. We present a case of a 40-year-old woman who has a history of surgical resection of a large uterine leiomyoma and then subsequently presented with benign metastasizing leiomyomas to her lungs. Due to her tumor being estrogen receptor (ER) positive and progesterone receptor (PR) positive, she was empirically treated with anastrozole with sustained clinical benefit. Molecular studies with Foundation One testing showed low mutational burden and mutational variants in five known cancer genes. Our findings have important clinical and pathogenetic implication for metastasizing uterine leiomyoma.

Introduction: Recent advances in cancer management may have transformed the overall prognosis of patients undergoing lung cancer resection. This study aimed to assess the changes in the long-term survival of patients undergoing surgery for lung cancer over the last 2 decades and to identify the risk factors modulating the postoperative prognosis.
Methods: This single-center retrospective study included nonsmall cell lung cancer patients who underwent lung resection between 2008 and 2020.

Purpose: Gadoxetic acid-enhanced hepatobiliary phase T-weighted (Tw) MRI is effective for the detection of focal liver lesions but lacks sufficient T contrast to distinguish benign from malignant lesions. Although the addition of T, diffusion, and dynamic contrast-enhanced Tw imaging improves lesion characterization, these methods often do not provide adequate spatial resolution to identify subcentimeter lesions. This work proposes a high-resolution, volumetric, free-breathing liver MRI method that produces colocalized fat-suppressed, variable Tw images from a single acquisition, thereby improving both lesion detection and characterization.

Myoepithelial carcinoma (MECA) is a malignant neoplasm composed exclusively of myoepithelial cells and accounts for less than 1% of all salivary gland tumors. Its diagnosis is often challenging due to histologic overlaps with benign lesions and its variable morphologic presentation. Although molecular profiling has emerged as a valuable tool in salivary gland tumor classification, the genetic landscape of MECA remains incompletely defined.

Objective: To develop a deep learning radiomics(DLR)model integrating PET/CT radiomics, deep learning features, and clinical parameters for early prediction of bone oligometastases (≤5 lesions) in breast cancer.
Methods: We retrospectively analyzed 207 breast cancer patients with 312 bone lesions, comprising 107 benign and 205 malignant lesions, including 89 lesions with confirmed bone metastases. Radiomic features were extracted from computed tomography (CT), positron emission tomography (PET), and fused PET/CT images using PyRadiomics embedded in the uAI Research Portal.

Background: Paragangliomas (PGLs) are rare neuroendocrine tumors originating from the extra-adrenal autonomic paraganglia with a strong genetic background. pathogenic variants are associated with the highest rate of malignancy in PGLs. Most head and neck paragangliomas (HNPGs) are asymptomatic and benign, and multiple metastases are rare.
