Primary uterine T-cell lymphoma with metastasis in an Atlantic spotted dolphin (Stenella frontalis), Canary Islands, Spain.

We describe gross, histopathologic, and immunonocytologic features of a primary uterine T-cell lymphoma with multiple metastases in an adult female Atlantic spotted dolphin (Stenella frontalis). Neoplastic T-cell lymphocytes (CD3+) partially effaced the uterus, ovaries, mesosalpinx, and urinary bladder and variably infiltrated abdominal and thoracic organs. Herpesvirus and morbillivirus PCR were negative.
