Inflammatory myofibroblastic tumor (IMT) of the oral cavity is an extremely rare finding. The etiology and pathogenesis of IMT is controversial and unclear. The tumor requires complete surgical excision and continuous monitoring of clinical consequences. The present article describes the clinical, histological, operative and immunohistochemical features of a case of IMT in the mandibular retromolar region of an 8-year-old male. Histologically, the lesion shows myofibroblastic spindle cell proliferations with infiltrative margins in an inflammatory background. Immunohistochemically, the myofibroblastic spindle cells in the present case were positive for α-smooth muscle actin and CD68 due to which the diagnosis of IMT was confirmed.

Cardiorenal syndrome (CRS) is represented as an intricate dysfunctional interplay between the heart and kidneys, marked by cardiorenal inflammation and fibrosis. Unlike other organs, the repair process in cardiorenal injury involves a regenerative phase characterized by proliferation and polyploidization, followed by a subsequent pathogenic phase of fibrosis. In CRS, acute or chronic cardiorenal injury leads to hyperactive inflammation and fibrotic remodeling, associated with injury-mediated immune cell (Macrophages, Monocytes, and T-cells) infiltration and myofibroblast activation.

Fibrosis represents a terminal pathological manifestation encountered in numerous chronic diseases. The process involves the persistent infiltration of inflammatory cells, the transdifferentiation of fibroblasts into myofibroblasts, and the excessive deposition of extracellular matrix (ECM) within damaged tissues, all of which are characteristic features of organ fibrosis. Extensive documentation exists on fibrosis occurrence in vital organs such as the liver, heart, lungs, kidneys, and skeletal muscles, elucidating its underlying pathological mechanisms.

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.
