A 17-month-old intact male Djungarian hamster (Phodopus sungorus) was presented with an axillary mass. Fine needle aspiration cytology of the mass showed a malignant epithelial cell tumor. Histopathological examination of the surgically removed mass confirmed a complex apocrine gland adenocarcinoma. Twenty days postoperatively, the mass recurred in the same area, and the patient died while waiting for the second surgical removal. This is the first report of the cytology, histopathology, and postoperative recurrence of apocrine gland adenocarcinoma in a Djungarian hamster.
