The ancient schwannoma is a rare variant of a neurilemoma with a course typical of a slow-growing benign neoplasm. Histologically, it can be confused with a malignant mesenchymal tumor because of increased cellularity, nuclear pleomorphism, and hyperchromatism. Despite the degree of nuclear atypia, mitotic figures are absent. We describe the clinical and histopathologic features of an ancient s...

PATIENT A case of Turner's syndrome developing a leiomyosarcoma of the oropharynx and metachronous neurogenic tumors (mediastinal 'ganglioneuroblastoma intermixed', subcutaneous neurilemoma) is described. DISCUSSION To our knowledge, this case is the second reported leiomyosarcoma in a patient with Turner's syndrome. Also the site of involvement (palate and oropharynx) is particularly unusual...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

O Neurilemoma ou Schwannoma é uma neoplasia benigna de proveniência neural originado na célula Schwann, que pode ser considerado relativamente incomum, e atinge tecidos moles da região cabeça pescoço, sendo notados nessas regiões em 25 % a 48% dos casos. diagnóstico realizado pelo exame histopatológico, o tratamento mais indicado excisão cirúrgica conservadora, com prognóstico favorável, não de...

Schwannoma, (also called neurilemoma, neurinoma) is a benign tumor originating from nerve sheath of the Schwann cells. They rarely occur in gastrointestinal tract. We report a rare case of colonic schwannoma in a 38-year-old woman presenting with worsening right-sided pelvic pain, discovered after laparoscopic right-colon resection performed after the detection of a atypical polypoid mass in th...
