原发性中耳类癌(Primary carcinoid of the middleear)是极为少见的肿瘤。自从1980年6月,Murphy等首次描述以来,国外文献陆续有零星的报道,经检索文献到1999年底国外文献有约30余例报道,而国内文献尚未见报道。由于该肿瘤有其独特的临床特点及预后,对这种肿瘤的临床及病理特点的正确认识就非常必要。 Primary carcinoid of the middle ear is a very rare tumor. Since the first description by Murphy et al. In June 1980, foreign literature has been reported sporadically. By the end of 1999, some 30 literatures have been reported on foreign literature, but no domestic literatures have been reported yet. As the tumor has its own unique clinical features and prognosis, a correct understanding of the clinical and pathological features of this tumor is necessary.
