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 schwannoma of the orbit.
古老型神经鞘瘤是神经鞘瘤的一种罕见变体，具有典型的缓慢生长良性肿瘤病程。在组织学上，由于细胞增多、核多形性和核深染，它可能会与恶性间叶性肿瘤混淆。尽管有核异型性程度，但无有丝分裂象。我们描述了一例眼眶古老型神经鞘瘤的临床和组织病理学特征。
