The morphogenesis of mammalian cutaneous glands is considered based on the analysis of the literature and our own original data with the focus on the issues of gland polymorphism and specific features in postnatal development (from the case study of circumanal hepatoid glands of newborn domestic dogs), including the features reflecting the evolutionary relationships of various types of cutaneous glands. The hepatoid glands are a component of the glandular complex ofthe hair follicle, which also includes sebaceous and sweat glands; have a specific structure; and produce protein secretion by a merocrine pathway. Characteristic of these glands are wide polymorphism, sex- and age-related differences in the degree of development, occurrence in only a few phylogenetically related mammalian taxa (even-toed ungulates and carnivores); and a signaling type of their secretion. The data support the "generative concept," relying on the idea of a separate and independent origination of diverse derivatives of the external integuments.
基于文献分析和我们自己的原始数据，对哺乳动物皮肤腺的形态发生进行了研究，重点关注腺体多态性问题以及出生后发育的特定特征（以新生家犬肛周肝样腺的案例研究为例），包括反映各种类型皮肤腺进化关系的特征。肝样腺是毛囊腺复合体的一个组成部分，该复合体还包括皮脂腺和汗腺；具有特定结构；并通过局部分泌途径产生蛋白质分泌物。这些腺体的特征是多态性广泛、发育程度存在性别和年龄差异、仅在少数系统发育相关的哺乳动物类群（偶蹄目和食肉目）中出现；以及其分泌物的信号传导类型。这些数据支持“生成概念”，该概念基于外部被膜不同衍生物单独且独立起源的观点。
