A 10-month-old male Campbell's Russian hamster (Phodopus campbelli) presented with a mass on the left forelimb. The mass was surgically excised, and the results of histopathology yielded a diagnosis of cutaneous botryomycosis, with corresponding clusters of large colonies of Gram-positive cocci. The results of the bacteriologic examination revealed Staphylococcus epidermidis. There was no evidence of patient immunosuppression based on diagnostic test results (e.g., hematology, plasma biochemistry panel, and serum electrophoresis). The mass recurred 5 months after resection. Surgical treatment was declined by the owner and an attempt to treat with antimicrobial medication was met with limited success. The animal was euthanized 7 months following the initial presentation. On histopathologic examination, a recurrent cutaneous botryomycosis was identified, associated with hepatic and splenic extramedullary granulopoiesis and hepatic pyogranulomas without granules and identifiable bacteria.
