Multimammate rat, Mastomys natalensis, 16-month-old, female |
A 16 month old female multimammate rat, Mastomys natalensis, that was part of a breeding pair, was initially noted to have a small subcutaneous lesion in the right axillary region that slowly progressed to a 2.5 centimeter in diameter firm, multilobular mass. Due to the rat??s recent poor reproductive performance, surgical intervention was not considered. The rat was euthanized and submitted for pathological examination. |
