Because symptoms and radiological examinations of this disease are generally nonspecific, the diagnosis is often difficult. Diagnosis can be confirmed by the immunohistochemical profile of staining with HMB-45 and S-100. This study deals with two cases of nonspecific clinical features. The factors of misdiagnosis were discussed and the lesson was summarized.展开更多
