Abstract |
The aim of this study was to identify patterns of epidermal and hair
follicular tumours in dogs and cats. A total of 50 samples were
collected from skin lesions. Hair follicular tumours were examined with
routine histological method but the malignant epidermal tumours were
examined with immunohistochemical technique. Grading for all of the
mentioned markers was as follows: not stained (-), stained less than 10%
(1+), stained 10-50% (2+), and stained more than 50% (3+). According to
the immunohistochemical staining results, regardless of the type of
animal, P53 expression levels in samples of basal cell carcinoma were
(1+) in one sample and (2+) in three, while all cutaneous lymphosarcoma
samples were (2+). In addition, CK8 expression levels in samples of
basal cell carcinoma were (1+) in three samples and (3+) in one sample.
Ki67 expression levels in the cutaneous lymphosarcoma samples were (1+)
in two samples and (2+) in one sample. Finally, CD99 expression levels
in all cutaneous lymphosarcoma samples were (2+). Combined diagnostic
panels such as CK8/P53 markers for basal cell carcinoma and
P53/Ki67/CD99 markers for cutaneous lymphosarcoma diagnosis are useful
diagnostic methods in dogs and cats.
