Management of proliferative thrombovascular necrosis of pinna in a Chippiparai dog

Abstract

A three-year-old male, Chippiparai dog was presented to the Dermatology unit of Madras Veterinary College Hospital with the complaint of bleeding from right ear tip. History revealed normal appetite, regular deworming and vaccination schedule (recent Anti rabies vaccination). The general clinical examination revealed parameters within the normal range except for the presence of a wedge-shaped ulcerated lesion at the ear tip. Haemogram and serum biochemistry revealed parameters within the normal range. Based on the history of recent vaccination and clinical presentation, the case was diagnosed as proliferative thrombovascular necrosis of the pinna. Treatment was initiated with oral pentoxifylline, doxycycline, niacinamide, vitamin E supplementation and topical tacrolimus application. Uneventful recovery was noticed after one month of treatment.
