An osteoma of the external meatus the size of a hazelnut was found in a 30-year-old man, arising from the bony edge of the external meatus near the tympanomastoid fissure. Histology showed epithelial cysts, trabeculae, blood-forming areas, fat cells, connective tissue and blood vessels. The site of origin and histological findings seem to indicate true hamartoma.
在一名30岁男性中发现外耳道有一个榛子大小的骨瘤,起源于外耳道靠近鼓乳裂的骨边缘。组织学检查显示有上皮囊肿、小梁、造血区域、脂肪细胞、结缔组织和血管。起源部位和组织学检查结果似乎表明这是一个真正的错构瘤。
