Squamous cell carcinoma of ventral abdominal region in a heifer developing since last more than one month and its surgical management is reported and placed on record.
Squamous cell carcinoma is a very common malignant neoplasm of squamous epithelium of all domestic animals especially the aged one, but there is no known breed or sex predilection in cattle. The tumor has been found in all areas of skin, eyes and horns of domestic animals, but the mucocutaneous junctions are commonly involved in horses and cattle and it has tendency to develop in areas of unpigmented skin (Nair and Sastry, 1954; Sastry, 1979). This report communicates squamous cell carcinoma of ventral abdominal region in a heifer and its surgical management.
History and Observations
A 3-year-old heifer was referred for treatment with the history of hard swelling (9´6cm) on the ventral abdominal region. The growth started developing since last more than one month.The growth was very small which increased in size gradually and was therefore brought to the clinics for treatment. The growth on clinical examination looked hard and ulcerative in nature. It was therefore, decided to excise the growth. After 24 hours of fasting the animal was controlled in a right lateral recumbency and premeditated with Diazepam@0.5mg/Kg Intravenously. Local anesthesia was achieved by infiltration of 2%lignocaine hydrochloride around the growth in a ring fashion. A six-inch long elliptical incision around the base of the swelling was made. The bleeding vessels were legated and the growth was excised and curetted out completely. Before closure of the wound, it was cauterized by strong solution of Potassium Per magnate. The wound was closed with braided silk thread #2 in a routine manner. Post-operatively injection Wolicycline DS (Wockhardt Ltd, Pune) 5ml was given intramuscularly for 5 days. Injection Proxyvet DS (Wockhardt Ltd, Pune) 5ml was given intramuscularly for 3 days. The wound was dressed with antiseptic cream. Skin sutures were removed on 10th post-operative day.
Results and discussion
The excised growth weighed about 400gm. It was preserved in 10%formalin and sent for histopathological examination.The histopathological examination revealed sqamous cell carcinoma. The growth was of bigger size at the base than it looked before cutaneous incision. Sqamous cell carcinoma is commonly seen in the areas of eyes and horn in the domestic animals. Carcinoma cause destruction of tissues and invade the surrounded tissues (Frank, 1981). In the present case the carcinoma developed at the ventral abdominal region and with its gradual increase in the size the animal looked like a bull as the growth resembled the prepuce. The growth was excised and the area was cauterized to prevent reoccurrence. Skin was sutured and wound healed uneventfully. After about one year the animal was re-examined. No recurrence was observed. The animal was quite healthy.
