Abstract:
Sarcoid is cutaneous tumour in horses, mules and donkeys and histologically similar to fibrosarcoma with limited malignancy. Commonly seen around nostrils, lips, neck, shoulder, lower part of legs, back, prepuce and face region. The present case reported a nodular ulcerating growth in the dewlap (brisket) region of the mule aged 6 years. This tumour was exposed to trauma and ulceration with supervening infection. Grossly, the growth appeared to be mixed form of sarcoid. The histopathological findings revealed irregular hyperplasia of the epidermis as characterized by deep rete ridges along with highly cellular mass arranged in interlacing network with small to moderate sizes of bundles of pleomorphic spindle cells of fibroblast origin suggesting nodular-fibroblastic sarcoid. An area of ulcerations with secondary bacterial infections was also noted. The case did not respond to standard Anthiomaline treatment hence the growth was surgically excised. Regular antibiotics along with localized antiseptic dressing resulted in complete recovery of animal.
