Apocrine cystomatosis is a rare condition characterized by clusters of cystically dilated sweat glands or other specialized apocrine glands. Cystic dilation of cutaneous sweat glands has been described in humans, dogs, and cats, but not in pigs, to our knowledge. We describe herein linear, brown, colloid-filled cavities < 1 cm diameter within the subcutaneous fat of the entire dorsal region of carcasses of three 6-mo-old pigs. These incidental findings were detected during meat inspection in 3 different slaughterhouses in Catalonia, Spain. Histopathology revealed multiple cystic cavities lined by flattened glandular epithelium, filled with proteinaceous material, and corresponding to cystic hyperplasia of sweat glands.

三头屠宰猪的皮肤顶泌性膀胱肉瘤病。

顶泌性膀胱瘤病是一种罕见的疾病，其特征是成簇的囊性扩张性汗腺或其他特异的顶泌腺。据我们所知，人类，狗和猫中都描述了皮肤汗腺的囊性扩张，但猪中没有。我们在此描述了三只6个月大的猪的car体整个背部区域的皮下脂肪内直径小于1厘米的线性，棕色胶体填充空腔。这些偶然发现是在西班牙加泰罗尼亚的3个不同的屠宰场进行肉类检查时发现的。组织病理学显示多个囊性腔被扁平的腺上皮衬里，内充满蛋白质物质，与汗腺的囊性增生相对应。
