title: Histological investigations on the skin of the mammary gland of mares.
abstract: The purpose of the study was to give a histological picture of the different skin regions of the mammary gland in mares. Special emphasis on the dark coating in the sulcus intermammarius was given. As a result, the dark pigmented udder skin can be subdivided into the skin of the Corpus mammae, the sulcus intermammarius and the teat skin. In the sulcus intermammarius the whole epidermis was considerably thicker than usual, especially the stratum corneum (up to 70 layers of cornified layers) and the stratum spinosum. In general, the squamous keratinocytes were unusually large. The histological preparations of the coating revealed a stratum corneum instead of a supposed secretion of the sebaceous glands. The dermal papillae ended immediately below the stratum corneum.
