The granular cell tumor (GCT) is a rare neoplasm derived from Schwann cells and is considered to be a benign tumor. The vulvar region is one of the common sites for these lesions. Vulvar occurrence of GCT constitutes about 7% of cases. To our knowledge, this is the first case of granular cell tumor of the vulva on an episiotomy scar. GCT should be(More)
V ascular malformations result from the aberrant development of vascular elements during embryogenesis and fetal maturation. Despite apparent endothelial quiescence, some vascular malformations can expand rapidly during adolescence or pregnancy, after a surgical procedure, or in response to trauma. The pathogenesis of vascular malformations is not well(More)
In cranioplasty complexity is proportional to the size of the defect, particularly if greater than 50 cm2. If the patient's own bone flap is not available, allogenic frozen bone graft can be used instead. Between June 1990 and June 1995 twenty cranioplasties with allogenic frozen bone grafts were performed. Age of patients ranged between 23 and 63 years(More)
Rat dorsal root regeneration was studied after 6th and 7th cervical root surgical removal and replacement with an autologous graft of peripheral nerve harvested from the surval nerve from dorsal root ganglion to dorsal horn. Histological studies showed axonal regeneration within the grafts. When the distal end of the graft was placed inside the posterior(More)
BACKGROUND Melanoma escape mechanisms include immunosuppressive and angiogenic cytokine production. OBJECTIVE We sought to determine vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) expression by immunohistochemistry, and soluble circulating plasma levels of VEGF, bFGF, IL-10, and transforming growth factor-beta2 in(More)
An increased number of mast cells (MCs) is found in renal specimens of patients with diseases associated with persistent chronic inflammation. MCs proliferation is partly dependent on the presence of T lymphocytes. Both chronic inflammation and T-lymphocytes are essential in the development of chronic rejection (CR), and probably for the infiltration of(More)
