In this case study, sweat gland carcinoma associated with plasmacytoma was described in a 5.5-year-old male mongrel dog suffering from a swelling in the pectoral region. Macroscopically, the biopsy material taken from the pectoral region was 3x5x3 cm in size, 12 g in weight, covered with skin and of elastic consistency, and presented with an ulcerous area nearly 2 cm in diameter on the upper surface. The cross-section had a multilobular appearance and contained cystic structures, which partly contained a serous fluid. Following routine tissue processing, the biopsy material was stained with haematoxylin-eosin (HE). Histologically, glandular structures composed of anaplastic sweat gland epithelial cells, which varied from round to oval in shape and contained hyperchromatic nuclei with evident nucleoli, were observed. In-between these glandular structures many anaplastic plasma cells existed.
