Clinical experiences with cytology in the dog

In a retrospective study (1995) cytological diagnoses of 3987 specimen of d ifferent origin in the dog were evaluated. Biopsies were performed at the D epartment of Clinical Sciences of Companion animals at the University of Ut recht or sent in by external practitioners. Biopsies were obtained from dif ferent regions including skin/subcutis, mammary gland, lymph node, external ear canal, kidney urinary bladder, urethra, prostatic gland, testes, bone, bone marrow, synovia, nose, oral cavity, cerebrospinal fluid bronchial lav age, lung, spleen, liver, conjunctiva, and retrobulbar region. The majority of biopsies were obtained from skin/subcutis (n=1815), lymph node (n=706), and mammary gland (n=415). A high percentage of no-diagnostic biopsies wer e observed with biopsies of lung, mammary gland, cerebrospinal fluid, exter nal ear canal, and oral cavity. The frequencies of diagnoses in the differe nt areas will be presented and the diagnostic indications of cytology are d iscussed.
