AI Article Synopsis

  • The case of a 60-year-old man with multiple intraosseous inflammatory myofibroblastic tumors presented with severe symptoms, including headaches and jaw pain, leading to a rapid deterioration of his condition.
  • Following MRI and bone scintigraphy, multiple tumors were identified in his skull, jaw, and other bones, necessitating surgical intervention.
  • Treatment involved tumor resection, corticosteroid therapy for swelling, and follow-up radiotherapy, highlighting the tumors' aggressive nature and the need for careful management to differentiate them from malignant tumors.

Article Abstract

Background And Importance: The authors report a rare case of multiple intraosseous inflammatory myofibroblastic tumors presenting with an aggressive clinical course.

Clinical Presentation: A 60-year-old man presented with a 3-month history of headache and 2 weeks of jaw pain. Magnetic resonance imaging showed a homogeneously enhancing mass in the right parietal bone with subcutaneous and intracranial invasion. Bone scintigraphy revealed 4 intraosseous lesions involving the cranium, mandible, ischium, and calcaneum. After admission, the patient showed left hemiparesis and seizures caused by rapid intracranial tumor extension. The cranial and mandible tumors were resected. Histopathological examinations of both specimens revealed myofibroblastic spindle cell proliferation with inflammatory cell infiltration, and a diagnosis of inflammatory myofibroblastic tumor was made. Two days postoperatively, the patient presented with a high fever and disturbance of consciousness with swelling of the subcutaneous tissues of the head and mandibular lesions. Magnetic resonance imaging revealed a massive intracranial extension of the tumor. Corticosteroid therapy induced remarkable shrinkage of all lesions, and relief from symptoms was obtained. Radiotherapy was then performed for residual tumors.

Conclusion: Multiple intraosseous inflammatory myofibroblastic tumors of the bone are very uncommon and may mimic malignant tumors. It is important to recognize that this entity can occur in the cranium and as multiple bony lesions. The recommended treatment is complete surgical resection with adjuvant steroid treatment. Considering the aggressive nature of this entity, additional chemo- and/or radiotherapy may be warranted.

The recent uncovering of fibroblast heterogeneity has given great insight into the versatility of the stroma. Among other cellular processes, fibroblasts are now thought to contribute to the coordination of immune responses in a range of chronic inflammatory diseases and cancer. While the pathologic roles of myofibroblasts, inflammatory fibroblasts and cancer associated fibroblasts in disease are reasonably well understood, the mechanisms behind their activation remain to be uncovered.

Inflammatory myofibroblastic tumors (IMTs) are rare mesenchymal neoplasms with intermediate biological potential and are characterized by spindle-shaped myofibroblastic cells and significant inflammatory infiltrates. This case report describes a 24-year-old male with diabetes who was admitted to the hospital for over three days of vomiting and abdominal pain and was initially diagnosed with diabetic ketoacidosis. Upon admission, an abdominal CT scan revealed a large cystic-solid mass in the abdominal cavity and multiple nodules in the mesentery, omentum, and peritoneum, suggesting a preliminary diagnosis of an intra-abdominal mesenchymal tumor with peritoneal metastasis.

Immunity suffers a function deficit during aging, and the incidence of cancer is increased in the elderly. However, most cancer models employ young mice, which are poorly representative of adult cancer patients. We have previously reported that Triple-Therapy (TT), involving antigen-presenting-cell activation by vinorelbine and generation of TCF1-stem-cell-like T cells (scTs) by cyclophosphamide significantly improved anti-PD-1 efficacy in anti-PD1-resistant models like Triple-Negative Breast Cancer (TNBC) and Non-Hodgkin's Lymphoma (NHL), due to T-cell-mediated tumor killing.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Inflammaging, a state of chronic low-grade inflammation associated with aging, has been linked to the development and progression of various disorders. Cellular senescence, a state of irreversible growth arrest, is another characteristic of aging that contributes to the pathogenesis of cardiovascular pathology. Senescent cells accumulate in tissues over time and secrete many inflammatory mediators, further exacerbating the inflammatory environment.
