Abstract
Asian and African elephants are frequently afflicted by foot disorders that can be very
challenging to manage even with aggressive therapy. Such conditions may have indirect
life-threatening effects. Mohs’ paste (zinc chloride based escharotic agent) was used to
treat a female Indian elephant (Elephas maximus indicus) aged 39 years
with foot disorder at Kanazawa Zoological Gardens. Degenerated hyperplastic tissue was
observed inside the hoofs of digits 2 and 5. Mohs’ paste was applied on the lesions, which
coagulated the hyperplastic tissue and restrained its proliferation. Subsequently, the
hyperplastic tissue could be trimmed with little pain, and the disorder became manageable.
Mohs’ paste treatment was effective and is expected to be an alternative treatment for
hoof disorder.

Abstract
In veterinary medicine, the management of malignant skin wounds is highly challenging. We conducted a study on seven case animals (four dogs and three cats) which presented with malignant skin wounds. All seven animals had signs and symptoms which were controlled following treatment with a modified Mohs paste. Upon obtaining informed consent from their owners, the animals requiring management of malignant wounds were enrolled in this study. The modified Mohs paste was prepared by mixing zinc chloride, zinc oxide starch powder, glycerin, and distilled water. The modified Mohs paste was topically applied to and left to remain on the malignant wounds for one hour, under controlled conditions. Once the paste was removed, the wounds were irrigated with a solution of sterile saline. At the first examination, the wounds of each animal were observed for signs of exudate, malodor, and bleeding. In every case, visible improvement was observed immediately after the modified Mohs paste treatment. Specifically, the size of the malignant wounds, and the number of times the dressing gauze required changing, significantly decreased (p < 0.05 and p < 0.01, respectively). The open malignant skin wounds caused by mammary gland tumors disappeared in two cases. The Mohs paste has been shown to be a viable option for the palliative treatment in canine and feline malignant skin wound management.
