Posterior mediastinal angiomyxolipoma with spinal canal extension. (26/36)

BACKGROUND: Angiomyxolipoma is a benign tumor considered as a variant of lipoma and that occurs mainly in the subcutis. The mediastinal location hasn't been previously reported. AIM: To describe the radiological features of this tumor in its posterior mediastinal location and to confront them to the pathological features. CASE REPORT: We report the case of a 49-year-old woman who was admitted for chest wall pain and neurologic disturbance of her two lower limbs. The chest X-ray showed a posterior mediastinal opacity. On CT examination, this mass contained some small areas of fat and enhanced intensely. Microscopic examination of the excised mass confirmed the diagnosis of posterior mediastinal angiomyxolipoma. CONCLUSION: Mediastinal location of angiomyxolipoma hasn't been previously reported. Clinicians and radiologists should be aware that this diagnosis should be suggested, among others, when there is a posterior mediastinal mass that contains fat and that intensely enhances with a possible spinal cord extension.  (+info)

Oral soft-tissue angiolipoma: report of two cases of rare oral lipomatous lesion with emphasis on morphological and immunohistochemical features. (30/36)

Oral angiolipomas are exceedingly rare and little is known about their morphological and etiological features. Here, we report two cases of oral angiolipoma and discuss their clinicopathological and immunohistochemical features, focusing on endothelial markers. Both lesions presented mature adipocytes interspersed by small blood vessels containing fibrin thrombi. Immunohistochemical analysis showed numerous mast cells and expression of CD34, vascular endothelial growth factor, intercellular adhesion molecule-1, interferon-gamma and interleukin 6 in most endothelial and stromal cells. Mast cell-endothelial cell interaction may be responsible for the reactive or neoplastic origin of the vascular proliferation of these entities.  (+info)
