Myofibroma of the external auditory canal: report of an adult case.
Myofibroma is a benign fibrous proliferative disease generally reported to occur in neonates and children. Similar lesions have been reported in adults, but solitary tumours affecting the external auditory canal are extremely rare. Only one such case has been reported in the literature.
The case of solitary myofibroma occurring in the external auditory canal of a 42-year-old woman is presented. The diagnosis of myofibromatosis was made on the basis of its histological appearance and corroborated by immunohistochemical staining.
Clinicians and pathologists must be aware that myofibromatosis may occur in adults at extremely rare locations. Myofibroma should be included in the differential diagnosis of fibrous lesions in the external auditory canal.
外耳道肌纤维瘤：1例成人病例报告
肌纤维瘤是一种良性纤维增生性疾病，通常报道发生于新生儿和儿童。成人中也有类似病变的报道，但累及外耳道的孤立性肿瘤极为罕见。文献中仅报道过1例此类病例。
本文介绍了1例发生于42岁女性外耳道的孤立性肌纤维瘤病例。根据组织学表现做出肌纤维瘤病的诊断，并通过免疫组化染色得到证实。
临床医生和病理学家必须认识到肌纤维瘤病可能在成人的极罕见部位发生。肌纤维瘤应纳入外耳道纤维性病变的鉴别诊断中。
