Four cases of rhabdomyoma of the ear pinna in white eared adult cats are reported. The lesions were raised, non-ulcerated, red-purple, discoid nodules on the convex surface of the pinna. Histologically, the nodules consisted of interlacing bundles of spindle-shaped cells that occasionally had cross striations. Lesions have not recurred 2-3 years following surgical excision. Although a specific cause for tumour development was not found, the similarity among these cases suggests that common factors played a role in the development of the lesions.
本文报道了4例白耳成年猫耳廓横纹肌瘤病例。病变表现为耳廓凸面上隆起的、无溃疡的、红紫色盘状结节。组织学上，结节由交织的梭形细胞束组成，这些细胞偶尔有横纹。手术切除后2 - 3年病变未复发。虽然未发现肿瘤发生的具体原因，但这些病例之间的相似性表明，共同因素在病变的发生中起了作用。
