Middle ear tumors are diverse, but relatively uncommon. The most frequent tumor in the middle ear is glomus tumor, followed by others such as schwannoma and cholesteatoma. We experienced a case of Mucosa-associated lymphoid tissue hyperplasia as a middle ear tumor. The mass behind tympanic membrane appeared a hypervascular tumor, mimicking a glomus tumor, but the form of multiple separate masses in middle ear and mastoid cavity was the distinguishing feature that set it apart from a glomus tumor. Additionally, another characteristic was its tendency to easily shrink under pressure. This characteristic should be considered when encounter a hypervascular looking middle ear mass.

中耳肿瘤种类多样，但相对少见。中耳最常见的肿瘤是颈静脉球体瘤，其次是其他肿瘤，如神经鞘瘤和胆脂瘤。我们遇到一例黏膜相关淋巴组织增生作为中耳肿瘤的病例。鼓膜后的肿物表现为血管丰富的肿瘤，类似颈静脉球体瘤，但中耳和乳突腔内多个分离肿物的形态是其与颈静脉球体瘤的区别特征。此外，另一个特点是其在压力下容易缩小。遇到血管丰富的中耳肿物时应考虑这一特征。《喉镜》，134:1894 - 1896，2024年。
