The myofibroblastic tumor (MFT) is a very rare tumor, initially described in the lungs, and which involves exceptionally the heart. We report the unusual case of a 31 year-old female patient, in whom the tumor produced a bilateral pulmonary embolism and whose unique clinical demonstration was a longstanding fever. The tumor, located in the right ventricle, has been surgically completely excised with excellent results. We also make a review of literature of the various aspects of this pathology.

Metastasis and recurrence are the primary obstacles to long-term survival in colorectal cancer (CRC) patients. In this study, we employed single-cell RNA sequencing (scRNA-seq) to comprehensively delineate the transcriptomic landscape of primary and liver metastatic CRCs, and revealed novel cellular crosstalk between cancer cell subpopulation and myofibroblastic CAFs (myCAFs) at single-cell resolution. We identified a cancer cell subpopulation termed stem/transient amplifying-like (stem/TA-like) cells, which expressed genes associated with stem cell-like characteristics and metastatic potential.

Introduction: Low-grade myofibroblastic sarcoma (LGMS) is an atypical and extremely infrequent type of tumor, primary mass being usually present in subcutaneous and soft tissue. Bony involvement is very rare. It has a very high chance of recurrence locally due to its aggressive biological behavior, metastasis in other parts of body is rarely seen.

Inflammatory myofibroblastic tumor is a rare occurring benign tumor composed of myofibroblastic spindle cells. Lung inflammatory myofibroblastic tumor is difficult to diagnose and may mimic lung cancer or infectious etiology. Surgical intervention with final histopathologic confirmation remains the mainstay of diagnosis.

Purpose: Eyelid infiltrative basal cell carcinoma (iBCC) is the most common malignant tumor affecting the ocular adnexa, but studies on metabolic changes within its microenvironment and heterogeneity at the tumor invasive area are limited. This study aims to analyze metabolic differences among iBCC cell types using single-cell and spatial metabolomics analysis and to examine metabolic environment at the tumor invasive area.
Methods: Single-cell transcriptomic data of human basal cell carcinoma (BCC) were clustered and visualized using Uniform Manifold Approximation and Projection.

Renal pseudotumors, which mimic tumors on imaging, pose diagnostic challenges that can lead to unnecessary interventions. Sensing ultrasound localization microscopy (sULM) is an advanced imaging technique that uses ultrasound imaging and microbubbles as sensors to visualize kidney functional units. This study aims to investigate whether sULM could differentiate between renal pseudotumors and tumors based on the presence of glomeruli.
