Localization of malignant schwannoma in the head and neck region is rare. Malignant schwannoma is a highly aggressive, slowly growing, encapsulated tumor of nerve sheath origin. The most common presentation of this tumor is a subcutaneous progressively enlarging mass with or without neurologic symptoms. These tumors arise from neurofibromas with or without von Recklinghausen disease, and most of the remains develop from peripheral nerve trunks. We report a case with recurrent malignant schwannoma of the scalp that is an uncommon presentation and discuss the clinicopathologic properties of this tumor.
头颈部恶性神经鞘瘤的定位很少见。恶性神经鞘瘤是一种高度侵袭性、生长缓慢、有包膜的神经鞘源性肿瘤。该肿瘤最常见的表现是皮下逐渐增大的肿块，伴有或不伴有神经症状。这些肿瘤起源于有或无冯雷克林霍增氏病的神经纤维瘤，大多数肿瘤由周围神经干发展而来。我们报告一例头皮复发性恶性神经鞘瘤，这是一种不常见的表现，并讨论该肿瘤的临床病理特征。
