Cystomatosis of the apocrine gland is a rare condition reported in dogs and cats. It is a non-neoplastic condition, characterized by several groups of dilated cystic sweat glands. Rarely a more widespread distribution can be observed. A captive female about 16 year-old melanic jaguar (Panthera onca) presented increased abdominal volume. Physical examination showed multiple floating nodular masses ranging from to 2 to 15cm in diameter located in the ventral abdomen. Other masses of smaller diameter (0.5-1.0cm) were present in the cervical region and in the back of the jaguar. These masses were surgically removed. Within this cyst had a odorless translucent content. Microscopically, between the mid and deep dermis there existed multiple cysts of different sizes, coated with a single layer of cuboidal cells. In some foci, there were rare papilliform projections of glandular epithelium. The cytoplasm was slightly eosinophilic with rare images of decapitation of the apex. The diagnostic of apocrine cystomatosis was performed through macroscopic and microscopic findings. |
