At least three normal-appearing and mature hair follicles containing hairs were found to be growing in a coiled manner within the intrinsic musculature of the anterior two thirds of a dog's tongue. An extensive review of the literature has shown that hair follicles are, indeed, found in some unusual places, but previous finding of their presence in the tongue has not been reported. Microscopic examination of serial sections failed to produce any evidence that these follicles were the result of some form of foreign body accident or teratomatous process. They appeared histologically normal in all respects and are assumed to be endogenous to the tongue. The embryologic development of these follicles is briefly commented upon.
在一只狗舌头前三分之二的固有肌层内，发现至少有三个外观正常且成熟的含有毛发的毛囊呈盘绕状生长。广泛的文献综述表明，毛囊确实存在于一些不寻常的部位，但此前尚未有在舌头中发现毛囊的报道。对连续切片的显微镜检查未能提供任何证据表明这些毛囊是某种形式的异物意外或畸胎瘤过程的结果。它们在组织学上各方面均表现正常，被认为是舌头内生的。对这些毛囊的胚胎发育进行了简要评论。
